- Add pytest8.patch to fix the tests with the new pytest

Wed Dec 27 09:35:46 UTC 2023 - Dirk Müller <>

- update to 1.13.1:
  * Fixed :class:`.Rewriter` so that more than two instances
    could be chained together correctly, also allowing multiple
    ``process_revision_directives`` callables to be chained.
  * Fixed issue where the method
    :meth:`.EnvironmentContext.get_x_argument` using the
    parameter would fail if an argument key were passed on the
    command line as a name alone, that is, without an equal sign
    ``=`` or a value. Behavior is repaired where this condition is
    detected and will return a blank string for the given key,
    consistent with the behavior where the ``=`` sign is
    present and no value.
  * Fixed issue where the "unique" flag of an ``Index`` would not
    be maintained when generating downgrade migrations.
  * Fixed bug in versioning model where a downgrade across a
    revision with two down revisions with one down revision
    depending on the other, would produce an erroneous state in
    the alembic_version table, making upgrades impossible
    without manually repairing the table.
  * Updated pep-484 typing to pass mypy "strict" mode, however
    including per-module qualifications for specific typing
    elements not yet complete.
  * This allows us to catch specific typing issues that have been
    ongoing such as import symbols not properly exported.

Thu Dec 14 09:13:53 UTC 2023 - Petr Gajdos <>

- update to 1.13.0:
  * Fixed issue where the ``alembic check`` command did not
    function correctly with upgrade structures that have multiple,
    top-level elements, as are generated from the "multi-env"
    environment template.
  * Updated logic introduced in :ticket:`151` to allow
    ``if_exists`` and ``if_not_exists`` on index operations also
    on SQLAlchemy  1.4 series. Previously this feature was
    mistakenly requiring the 2.0 series.
  * Replaced ``python-dateutil`` with the standard library module
  * Alembic 1.13 now supports Python 3.8 and above.
  * Fixed autogenerate issue where ``create_table_comment()`` and
    ``drop_table_comment()`` rendering in a batch table modify
    would include the "table" and "schema" arguments, which are
    not accepted in batch as these are already part of the top
    level block.
  * Additional fixes to PostgreSQL expression index compare
    feature. The compare now correctly accommodates casts and
    differences in spacing.
  * Added detection logic for operation clauses inside the
    expression, skipping the compare of these expressions.
  * To accommodate these changes the logic for the comparison of
    the indexes and unique constraints was moved to the dialect
    implementation, allowing greater flexibility.

Tue Nov 14 12:40:19 UTC 2023 - Dirk Müller <>

- update to 1.12.1:
  * Fixed regression caused by :ticket:`879` released in 1.7.0
    where the ".info" dictionary of ``Table`` would not render in
    autogenerate create table statements.
    This can be useful for custom create table DDL rendering
    schemes so it is restored.
  * Improved typing in the
    ectives` callable to better indicate that the passed-in type is
    :class:`.MigrationScript`, not the :class:`.MigrationOperation`
    base class, and added typing to the example at
    :ref:`cookbook_no_empty_migrations` to illustrate.
  * Repaired :class:`.ExecuteSQLOp` so that it can participate in
    "diff" operations; while this object is typically not present
    in a reflected operation stream, custom hooks may be adding
    this construct where it needs to have the correct
    ``to_diff_tuple()`` method.
  * Improved the ``op.execute()`` method to correctly accept the
  * ``Executable`` type that is the same which is used in
    SQLAlchemy ``Connection.execute()``.
  * Improve typing of the revision parameter in various command
  * Fixed autogen render issue where expressions inside of
    indexes for PG need to be double-parenthesized, meaning a
    single parens must be present within the generated ``text()``
  * Alembic now accommodates for Sequence and Identity that
    support dialect kwargs.
    This is a change that will be added to SQLAlchemy v2.1.

Mon Sep 25 22:38:26 UTC 2023 - Matej Cepl <>

- Clean up the SPEC file

Mon Sep 25 14:53:14 UTC 2023 - Ondřej Súkup <>

- update to 1.12.0
 * Added new feature to the "code formatter" function which allows standalone
   executable tools to be run against code, without going through the Python
   interpreter.  Known as the `exec` runner, it complements the existing
   `console_scripts` runner by allowing non-Python tools such as `ruff` to
   be used.
 * Change the default value of `.EnvironmentContext.configure.compare_type` to `True`.
   As Alembic's autogenerate for types was dramatically improved in
   version 1.4 released in 2020, the type comparison feature is now much
   more reliable so is now enabled by default.
 * Fixed issue where the `ForeignKeyConstraint.match` parameter would not be
   rendered in autogenerated migrations.
 * Fixed issue where the `revision_environment` directive in `alembic.ini`
   was ignored by the `alembic merge` command, leading to issues when other
   configurational elements depend upon `` being invoked within the
 * Added support for `op.drop_constraint()` to support PostgreSQL
   `ExcludeConstraint` objects, as well as other constraint-like objects
   that may be present in third party dialects, by resolving the `type_`
   parameter to be `None` for this case.   Autogenerate has also been
   enhanced to exclude the `type_` parameter from rendering within this
   command when  `type_` is `None`.

Sun Aug 13 19:32:21 UTC 2023 - Dirk Müller <>

- update to 1.11.2:
  * Added typing to the default script mako templates.
  * Added support in autogenerate for NULLS NOT DISTINCT in
  * the PostgreSQL dialect.
  * Fixed format string logged when running a post write hook
  * Added parameters if_exists and if_not_exists for index

Sat Jul 29 21:17:43 UTC 2023 - Dirk Müller <>

- update to 1.11.1:
  * As Alembic 1.11.0 is considered a major release (Alembic does
    not use semver, nor does its parent project SQLAlchemy;
    this has been `clarified <versioning_scheme>` in the documentation),
  * :ticket:`1130` modified calling signatures for most
    operations to consider all optional keyword parameters to
    be keyword-only arguments, to match what was always documented
    and generated by autogenerate. However, two of these
    changes were identified as possibly problematic without a
    more formal deprecation warning being emitted which were the
    ``table_name`` parameter to :meth:`.Operations.drop_index`,
    which was generated positionally by autogenerate prior to
    version 0.6.3 released in 2014, and
    ``type_`` in :meth:`.Operations.drop_constraint` and
    :meth:`.BatchOperations.drop_constraint`, which was
    documented positionally in one example in the batch documentation.
  * Fixed typing use of :class:`~sqlalchemy.schema.Column` and
    other generic SQLAlchemy classes.
  * Restored the output type of :meth:`.Config.get_section` to
    include ``Dict[str, str]`` as a potential return type, which
    had been changed to immutable ``Mapping[str, str]``.
    When a section is returned and the default is not used,
    a mutable dictionary is returned.
  * Added placeholder classes for :class:`~.sqla.Computed` and
  * :class:`~.sqla.Identity` when older 1.x SQLAlchemy versions
    are in use, namely prior to SQLAlchemy 1.3.11 when the
    :class:`~.sqla.Computed` construct was introduced.
    Previously these were set to None, however this
    could cause issues with certain codepaths that were using
    ``isinstance()`` such as one within "batch mode".
  * Correctly pass previously ignored arguments ``insert_before``
    and ``insert_after`` in ``batch_alter_column``
  * Argument signatures of Alembic operations now enforce
    keyword-only arguments as passed as keyword and not
    positionally, such as Operations.create_table.schema
    .Operations.add_column.type_, etc.
  * Fix autogenerate issue with PostgreSQL
    :class:`.ExcludeConstraint` that included sqlalchemy
    functions. The function text was previously rendered
    as a plain string without surrounding with ``text()``.
  * Fixed regression caused by :ticket:`1166` released in version
    1.10.0 which caused MySQL unique constraints with multiple
    columns to not compare correctly within autogenerate,
    due to different sorting rules on unique constraints vs.
    indexes, which in MySQL are shared constructs.
  * Repaired the return signatures for :class:`.Operations` that
    mostly return ``None``, and were erroneously referring to
    ``Optional[Table]`` in many cases.
  * Modified the autogenerate implementation for comparing
    "server default" values from user-defined metadata to not
    apply any quoting to the value before comparing it to the
    server-reported default, except for within dialect-specific
    routines as needed. This change will affect the format of
    the server default as passed to the
    lt` hook, as well as for third party dialects that implement
    a custom ``compare_server_default`` hook in their alembic
    impl, to be passed "as is" and not including additional
    quoting.   Custom implementations which rely on this quoting
    should adjust their approach based on observed formatting.
  * allow running async functions in the ``upgrade`` or
    ``downgrade`` migration function when running alembic using
    an async dialect. This function will receive as first argument
    an :class:`~sqlalchemy.ext.asyncio.AsyncConnection` sharing the
    transaction used in the migration context.

- tag sle15 build for new python

Fri May  5 22:12:29 UTC 2023 - Dirk Müller <>

- update to 1.10.4:
  * Added support for autogenerate comparison of indexes on
    PostgreSQL which include SQL sort option, such as
    ``ASC`` or ``NULLS FIRST``.
  * Fixed various typing issues observed with pyright, including
    issues involving the combination of :class:`.Function` and
  * Fixed error raised by alembic when running autogenerate after
    removing a function based index.
  * Fixed regression where Alembic would not run with older
    SQLAlchemy 1.3 versions prior to 1.3.24 due to a
    missing symbol. Workarounds have been applied for older
    1.3 versions.
  * Fixed issue regarding PostgreSQL :class:`.ExcludeConstraint`,
    where constraint elements which made use of :func:`.literal_column`
    could not be rendered for autogenerate. Additionally, using SQLAlchemy
    2.0.5 or greater, :func:`.text()` constructs are also supported within
    PostgreSQL :class:`.ExcludeConstraint` objects for autogenerate render.
  * Fixed issue in index detection where autogenerate change
    detection would consider indexes with the same columns but with
    different order as equal, while in general they are not equivalent
    in how a database will use them.
  * Recursive traversal of revision files in a particular
    revision directory is now supported, by indicating
    ``recursive_version_locations = true`` in alembic.ini.
  * Fixed issue where indexes on SQLite which include SQL
    expressions would not compare correctly, generating false
    positives under autogenerate. These indexes are now skipped,
    generating a warning, in the same way that
    expression-based indexes on PostgreSQL are skipped and
    generate warnings when SQLAlchemy 1.x installations are
    in use. Note that reflection of
    SQLite expression-based indexes continues to not yet be
    supported under SQLAlchemy 2.0, even though PostgreSQL
    expression-based indexes have now been implemented.
  * Properly escape constraint name on SQL Server when dropping
    a column while specifying ``mssql_drop_default=True`` or
    ``mssql_drop_check=True`` or ``mssql_drop_foreign_key=True``.

Fri Feb 10 12:36:15 UTC 2023 - Dirk Müller <>

- update to 1.9.3:
  * Fixed issue where rendering of user-defined types
    that then went onto use the .with_variant() method would
    fail to render, if using SQLAlchemy 2.0's version of variants.

Sat Jan 28 14:31:09 UTC 2023 - Dirk Müller <>

- update to 1.9.2:
  * Fixed typing definitions for :meth:`.EnvironmentContext.get_x_argument`.
    Typing stubs are now generated for overloaded proxied methods such as
  * Fixed regression caused by :ticket:`1145` where the string transformations
    applied to server defaults caused expressions such as ``(getdate())`` to no
    longer compare as equivalent on SQL Server, others.

Thu Jan  5 20:33:31 UTC 2023 - Dirk Müller <>

- update to 1.9.1:
    .. change::
        :tickets: 1145
        Fixed issue where server default compare would not work for string defaults
        that contained backslashes, due to mis-rendering of these values when
        comparing their contents.
    .. change::
        :tags: bug, oracle
        Implemented basic server default comparison for the Oracle backend;
        previously, Oracle's formatting of reflected defaults prevented any
        matches from occurring.
    .. change::
        :tags: bug, sqlite
        Adjusted SQLite's compare server default implementation to better handle
        defaults with or without parens around them, from both the reflected and
        the local metadata side.
    .. change::
        :tags: bug, mssql
        Adjusted SQL Server's compare server default implementation to better
        handle defaults with or without parens around them, from both the reflected
        and the local metadata side.

Thu Jan  5 19:06:37 UTC 2023 - Yogalakshmi Arunachalam <>

- Update to 1.9.0:
  * Added new Alembic command alembic check. This performs the widely requested feature of running an “autogenerate” comparison
    between the current database and the MetaData that’s currently set up for autogenerate, returning an error code if the two do not match,
    based on current autogenerate settings. Pull request courtesy Nathan Louie.
    See also Running Alembic Check to test for new upgrade operations
    References: #724
  * Fixed issue in tox.ini file where changes in the tox 4.0 series to the format of “passenv” caused tox to not function correctly,
    in particular raising an error as of tox 4.0.6.
  * Fixed typing issue where revision.process_revision_directives was not fully typed; additionally ensured all Callable and Dict arguments
    to EnvironmentContext.configure() include parameters in the typing declaration.
    Additionally updated the codebase for Mypy 0.990 compliance.
    References: #1110

Mon Aug  1 21:38:44 UTC 2022 - Dirk Müller <>

- update to 1.8.1:
  * Fixed bug where the SQLite implementation of
    :meth:`.Operations.rename_table` would render an explicit schema name for
    both the old and new table name, which while is the standard ALTER syntax,
     is not accepted by SQLite's syntax which doesn't support a rename across
    schemas. In particular, the syntax issue would prevent batch mode from
    working for SQLite databases that made use of attached databases (which are
    treated as "schemas" in SQLAlchemy).
  * Added an error raise for the condition where
    :meth:`.Operations.batch_alter_table` is used in ``--sql`` mode, where the
    operation requires table reflection, as is the case when running against
    SQLite without giving it a fixed ``Table`` object. Previously the operation
    would fail with an internal error.   To get a "move and copy" batch
    operation as a SQL script without connecting to a database,
    a ``Table`` object should be passed to the
    :paramref:`.Operations.batch_alter_table.copy_from` parameter so that
    reflection may be skipped.

Sat Jun  4 20:32:32 UTC 2022 - Arun Persaud <>

- update to version 1.8.0:
  * changed
    + [changed] [installation] Alembic 1.8 now supports Python 3.7 and
      above.  References: #1025
    + [changed] [environment] The “Pylons” environment template has
      been removed as of Alembic 1.8. This template was based on the
      very old pre-Pyramid Pylons web framework which has been long
      superseded by Pyramid.  References: #987
  * feature
    + [feature] [typing] PEP 484 typing annotations have been added to
      the and revision template files within migration
      templates. Pull request by Nikita Sobolev.  References: #764
  * usecase
    + [usecase] [operations] The op.drop_table() operation directive
      will now trigger the before_drop() and after_drop() DDL event
      hooks at the table level, which is similar to how the
      before_create() and after_create() hooks are triggered by the
      op.create_table() directive. Note that as op.drop_table()
      accepts only a table name and optional schema name, the Table
      object received by the event will not have any information
      within it other than the table name and schema name.
      References: #1037
    + [usecase] [commands] Added new token epoch to the file_template
      option, which will populate the integer epoch as determined by
      int(create_date.timestamp()). Pull request courtesy Caio
      Carvalho.  References: #1027
  * bug
    + [bug] [revisioning] Fixed issue where a downgrade using a
      relative revision would fail in case of multiple branches with a
      single effectively head due to interdependencies between
      revisions.  References: #1026
    + [bug] [batch] Fixed issue in batch mode where CREATE INDEX would
      not use a new column name in the case of a column rename.
      References: #1034

Sat Mar 26 20:27:41 UTC 2022 - Dirk Müller <>

- update to 1.7.7:
  * Fixed issue where using :meth:`.Operations.create_table` in conjunction
    with a :class:`.CheckConstraint` that referred to table-bound
    :class:`.Column` objects rather than string expressions would be added to
    the parent table potentially multiple times, resulting in an incorrect DDL
    sequence. Pull request courtesy Nicolas CANIART.
  * The ``logging.fileConfig()`` line in ```` templates, which is used
    to setup Python logging for the migration run, is now conditional on
    :attr:`.Config.config_file_name` not being ``None``.  Otherwise, the line
    is skipped as there is no default logging configuration present.
  * Fixed bug where an :meth:`.Operations.alter_column` operation would change
    a "NOT NULL" column to "NULL" by emitting an ALTER COLUMN statement that
    did not specify "NOT NULL". (In the absence of "NOT NULL" T-SQL was
    implicitly assuming "NULL"). An :meth:`.Operations.alter_column` operation
    that specifies :paramref:`.Operations.alter_column.type` should also
    specify include either :paramref:`.Operations.alter_column.nullable` or
    :paramref:`.Operations.alter_column.existing_nullable` to inform Alembic as
    to whether the emitted DDL should include "NULL" or "NOT NULL"; a warning
    is now emitted if this is missing under this scenario.

Mon Feb 14 21:37:49 UTC 2022 - Dirk Müller <>

- update to 1.7.6:
  * Add a new command alembic ensure_version, which will ensure that the Alembic
    version table is present in the target database, but does not alter its
  * Fixed regression where usage of a with_variant() datatype in conjunction with
    the existing_type option of op.alter_column() under batch mode would lead to an
    internal exception.
  * Implemented support for recognizing and rendering SQLAlchemy “variant” types
    going forward into SQLAlchemy 2.0, where the architecture of “variant”
    datatypes will be changing.
  * Added a rule to the MySQL impl so that the translation between JSON / LONGTEXT
    is accommodated by autogenerate, treating LONGTEXT from the server as
    equivalent to an existing JSON in the model.
  * Removed a warning raised by SQLAlchemy when dropping constraints on MSSQL
    regarding statement caching.

- update to 1.7.4:
  * Fixed a regression that prevented the use of post write hooks on python
    version lower than 3.9
  * Added missing attributes from context stubs.
  * Fixed issue where registration of custom ops was prone to failure due to
    the registration process running exec() on generated code that as of the
    1.7 series includes pep-484 annotations, which in the case of end user code
    would result in name resolution errors when the exec occurs

- specfile:
  * skip python 2 builds
  * require importlib-resources

- update to version 1.7.1:
  * Corrected "universal wheel" directive in setup.cfg so that
    building a wheel does not target Python 2. The PyPi files index
    for 1.7.0 was corrected manually. Pull request courtesy layday.
  * Fixed issue in generated .pyi files where default values for
    "Optional" arguments were missing, thereby causing mypy to
    consider them as required.
  * Fixed regression in batch mode due to :ticket:`883` where the
    "auto" mode of batch would fail to accommodate any additional
    migration directives beyond encountering an "add_column()"
    directive, due to a mis-application of the conditional logic that
    was added as part of this change, leading to "recreate" mode not
    being used in cases where it is required for SQLite such as for
    unique constraints.

- changes from version 1.7.0:
  * Fixed regression due to :ticket:`803` where the ".info" and
    ".comment" attributes of "Table" would be lost inside of the
    :class:`.DropTableOp` class, which when "reversed" into a
    :class:`.CreateTableOp` would then have lost these elements. Pull
    request courtesy Nicolas CANIART.
  * Enhance "version_locations" parsing to handle paths containing
    spaces.  The new configuration option "version_path_separator"
    specifies the character to use when splitting the
    "version_locations" string. The default for new configurations is
    "version_path_separator = os", which will use "os.pathsep" (e.g.,
    ";" on Windows).
  * Alembic 1.7 now supports Python 3.6 and above; support for prior
    versions including Python 2.7 has been dropped.
  * Batch "auto" mode will now select for "recreate" if the
    "add_column()" operation is used on SQLite, and the column itself
    meets the criteria for SQLite where ADD COLUMN is not allowed, in
    this case a functional or parenthesized SQL expression or a
    "Computed" (i.e. generated) column.
  * Make the "python-dateutil" library an optional dependency.  This
    library is only required if the "timezone" option is used in the
    Alembic configuration.  An extra require named "tz" is available
    with "pip install alembic[tz]" to install it.
  * Re-implemented the "python-editor" dependency as a small internal
    function to avoid the need for external dependencies.
  * Named CHECK constraints are now supported by batch mode, and will
    automatically be part of the recreated table assuming they are
    named. They also can be explicitly dropped using
    "op.drop_constraint()". For "unnamed" CHECK constraints, these are
    still skipped as they cannot be distinguished from the CHECK
    constraints that are generated by the "Boolean" and "Enum"
    datatypes.  Note that this change may require adjustments to
    migrations that drop or rename columns which feature an associated
    named check constraint, such that an additional
    "op.drop_constraint()" directive should be added for that named
    constraint as there will no longer be an associated column for it;
    for the "Boolean" and "Enum" datatypes, an "existing_type" keyword
    may be passed to "BatchOperations.drop_constraint" as well.
  * The dependency on "pkg_resources" which is part of "setuptools"
    has been removed, so there is no longer any runtime dependency on
    "setuptools". The functionality has been replaced with
    "importlib.metadata" and "importlib.resources" which are both part
    of Python std.lib, or via pypy dependency "importlib-metadata" for
    Python version < 3.8 and "importlib-resources" for Python version
    < 3.9 (while importlib.resources was added to Python in 3.7, it
    did not include the "files" API until 3.9).
  * Created a "test suite" similar to the one for SQLAlchemy, allowing
    developers of third-party dialects to test their code against a
    set of Alembic tests that have been specially selected to exercise
    back-end database operations. At the time of release, third-party
    dialects that have adopted the Alembic test suite to verify
    compatibility include `CockroachDB
    <>`_ and `SAP ASE
    (Sybase) <>`_.
  * Fixed issue where usage of the PostgreSQL "postgresql_include"
    option within a :meth:`.Operations.create_index` would raise a
    KeyError, as the additional column(s) need to be added to the
    table object used by the construct internally. The issue is
    equivalent to the SQL Server issue fixed in :ticket:`513`. Pull
    request courtesy Steven Bronson.
  * pep-484 type annotations have been added throughout the library.
    Additionally, stub .pyi files have been added for the
    "dynamically" generated Alembic modules "alembic.op" and
    "alembic.config", which include complete function signatures and
    docstrings, so that the functions in these namespaces will have
    both IDE support (vscode, pycharm, etc) as well as support for
    typing tools like Mypy. The files themselves are statically
    generated from their source functions within the source tree.

- update to 1.6.5:
  * feature
    + [feature] [autogenerate] Fix the documentation regarding the
      default command-line argument position of the revision script
      filename within the post-write hook arguments. Implement a
      REVISION_SCRIPT_FILENAME token, enabling the position to be
      changed. Switch from str.split() to shlex.split() for more
      robust command-line argument parsing.
    + [feature] Implement a .cwd (current working directory) suboption
      for post-write hooks (of type console_scripts). This is useful
      for tools like pre-commit, which rely on the working directory
      to locate the necessary config files. Add pre-commit as an
      example to the documentation. Minor change: rename some
      variables from ticket #819 to improve readability.

      CreateTableOp, etc. so that they no longer rely upon maintaining
      a persistent version of each schema object internally; instead,
      the state variables of each operation object will be used to
      produce the corresponding construct when the operation is

    + [bug] [regression] [versioning] Fixed additional regression
      nearly the same as that of #838 just released in 1.6.1 but
      within a slightly different codepath, where “alembic downgrade
      head” (or equivalent) would fail instead of iterating no

- changes from version 1.6.1:
  * bug
    + [bug] [regression] [versioning] Fixed regression in new
      revisioning traversal where “alembic downgrade base” would fail
      if the database itself were clean and unversioned; additionally
      repairs the case where downgrade would fail if attempting to
      downgrade to the current head that is already present.

- changes from version 1.6.0:
  * feature
    + [feature] [autogenerate] Fix the documentation regarding the
      default command-line argument position of the revision script
      filename within the post-write hook arguments. Implement a
      REVISION_SCRIPT_FILENAME token, enabling the position to be
      changed. Switch from str.split() to shlex.split() for more
      robust command-line argument parsing.
    + [feature] Implement a .cwd (current working directory) suboption
      for post-write hooks (of type console_scripts). This is useful
      for tools like pre-commit, which rely on the working directory
      to locate the necessary config files. Add pre-commit as an
      example to the documentation. Minor change: rename some
      variables from ticket #819 to improve readability.
  * bug
    + [bug] [autogenerate] Refactored the implementation of
      MigrateOperation constructs such as CreateIndexOp,
      CreateTableOp, etc. so that they no longer rely upon maintaining
      a persistent version of each schema object internally; instead,
      the state variables of each operation object will be used to
      produce the corresponding construct when the operation is
      invoked. The rationale is so that environments which make use of
      operation-manipulation schemes such as those those discussed in
      Fine-Grained Autogenerate Generation with Rewriters are better
      supported, allowing end-user code to manipulate the public
      attributes of these objects which will then be expressed in the
      final output, an example is["postgresql_concurrently"] = True.

      Previously, these objects when generated from autogenerate would
      typically hold onto the original, reflected element internally
      without honoring the other state variables of each construct,
      preventing the public API from working.
    + [bug] [environment] Fixed regression caused by the SQLAlchemy
      1.4/2.0 compatibility switch where calling .rollback() or
      .commit() explicitly within the context.begin_transaction()
      context manager would cause it to fail when the block ended, as
      it did not expect that the transaction was manually closed.
    + [bug] [autogenerate] Improved the rendering of op.add_column()
      operations when adding multiple columns to an existing table, so
      that the order of these statements matches the order in which
      the columns were declared in the application’s table
      metadata. Previously the added columns were being sorted
    + [bug] [versioning] The algorithm used for calculating
      downgrades/upgrades/iterating revisions has been rewritten, to
      resolve ongoing issues of branches not being handled
      consistently particularly within downgrade operations, as well
      as for overall clarity and maintainability. This change includes
      that a deprecation warning is emitted if an ambiguous command
      such as “downgrade -1” when multiple heads are present is given.

      In particular, the change implements a long-requested use case
      of allowing downgrades of a single branch to a branchpoint.

      Huge thanks to Simon Bowly for their impressive efforts in
      successfully tackling this very difficult problem.
    + [bug] [batch] Added missing batch_op.create_table_comment(),
      batch_op.drop_table_comment() directives to batch ops.

- Update to 1.5.8:
  * Fixed regression caused by SQLAlchemy 1.4 where the "alembic current"
    command would fail due to changes in the ``URL`` object.
  * Add async template to Alembic to bootstrap environments that use
    async DBAPI. Updated the cookbook to include a migration guide
    on how to adapt an existing enviroment for use with DBAPI drivers.
  * Fixed bug in versioning model where a downgrade across a revision with a
    dependency on another branch, yet an ancestor is also dependent on that
    branch, would produce an erroneous state in the alembic_version table,
    making upgrades impossible without manually repairing the table.
  * Changed the default ordering of "CREATE" and "DROP" statements indexes and
    unique constraints within the autogenerate process, so that for example in
    an upgrade() operation, a particular index or constraint that is to be
    replaced such as for a casing convention change will not produce any naming
  * Fixed issue where autogenerate rendering of ``op.alter_column()`` would
    fail to include MySQL ``existing_nullable=False`` if the column were part
    of a primary key constraint within the table metadata.
  * Added support for rendering of "identity" elements on
    :class:`.Column` objects, supported in SQLAlchemy via
    the :class:`.Identity` element introduced in version 1.4.
  * Adding columns with identity is supported on PostgreSQL,
    MSSQL and Oracle. Changing the identity options or removing
    it is supported only on PostgreSQL and Oracle.
  * To accommodate SQLAlchemy 1.4 and 2.0, the migration model now no longer
    assumes that the SQLAlchemy Connection will autocommit an individual
  * Modified the ``add_column()`` operation such that the ``Column`` object in
    use is shallow copied to a new instance if that ``Column`` is already
    attached to a ``table()`` or ``Table``.
  * Added rendering for the ``Table.prefixes`` element to autogenerate so that
    the rendered Python code includes these directives.
  * Alembic 1.5.0 now supports **Python 2.7 and Python 3.6 and above**, as well
    as **SQLAlchemy 1.3.0 and above**.
  * Add ```` file to alembic package to support invocation
    with ``python -m alembic``.
  * Removed deprecated ``--head_only`` option to the ``alembic current``

- update to version 1.4.3:
  * bug
    + Added support to drop named CHECK constraints that are specified
      as part of a column, rather than table wide. Previously, only
      constraints associated with the table were considered.
      References: #711
    + Fixed issue where the MySQL dialect would not correctly render
      the server default of a column in an alter operation, if the
      operation were programmatically generated from an autogenerate
      pass as it would not accommodate for the full structure of the
      DefaultClause construct.  References: #736
    + Fixed issue where the CAST applied to a JSON column when copying
      a SQLite table during batch mode would cause the data to be
      lost, as SQLite’s CAST with JSON appears to convert the data to
      the value “0”. The CAST is now skipped in a dialect-specific
      manner, including for JSON columns on SQLite. Pull request
      courtesy Sebastián Ramírez.  References: #697
    + The alembic current command no longer creates an alembic_version
      table in the database if one does not exist already, returning
      no version as the current version. This allows checking for
      migrations in parallel without introducing race conditions. Pull
      request courtesy Nikolay Edigaryev.  References: #694
    + Fixed issue where columns in a foreign-key referenced table
      would be replaced with null-type columns during a batch
      operation; while this did not generally have any side effects,
      it could theoretically impact a batch operation that also
      targets that table directly and also would interfere with future
      changes to the .append_column() method to disallow implicit
      replacement of columns.
    + Fixed issue where the mssql_drop_foreign_key=True flag on
      op.drop_column would lead to incorrect syntax error due to a
      typo in the SQL emitted, same typo was present in the test as
      well so it was not detected. Pull request courtesy Oleg
      Shigorin.  References: #716

- update to version 1.4.2:
  * bug
    + Fixed an issue that prevented the test suite from running with
      the recently released py.test 5.4.0.  References: #668
    + Fixed more false-positive failures produced by the new “compare
      type” logic first added in #605, particularly impacting MySQL
      string types regarding flags such as “charset” and “collation”.
      References: #671
    + Fixed issue in Oracle backend where a table RENAME with a
      schema-qualified name would include the schema in the “to”
      portion, which is rejected by Oracle.  References: #670
  * usecase
    + Adjusted autogen comparison to accommodate for backends that
      support computed column reflection, dependent on SQLAlchemy
      version 1.3.16 or higher. This emits a warning if the SQL
      expression inside of a Computed value changes between the
      metadata and the database, as these expressions can’t be changed
      without dropping and recreating the column. References: #669

Fri Mar  6 21:49:43 UTC 2020 - Arun Persaud <>

- update to version 1.4.1:
  * Fixed regression caused by the new “type comparison” logic
    introduced in 1.4 as part of #605 where comparisons of MySQL
    “unsigned integer” datatypes would produce false positives, as the
    regular expression logic was not correctly parsing the “unsigned”
    token when MySQL’s default display width would be returned by the
    database. Pull request courtesy Paul Becotte. References: #661
  * Error message for “path doesn’t exist” when loading up script
    environment now displays the absolute path. Pull request courtesy
    Rowan Hart. References: #663
  * Fixed regression in 1.4.0 due to #647 where unique constraint
    comparison with mixed case constraint names while not using a
    naming convention would produce false positives during
    autogenerate.References: #654
  * The check for matched rowcount when the alembic_version table is
    updated or deleted from is now conditional based on whether or not
    the dialect supports the concept of “rowcount” for UPDATE or
    DELETE rows matched. Some third party dialects do not support this
    concept. Pull request courtesy Ke Zhu.
  * Fixed long-standing bug where an inline column CHECK constraint
    would not be rendered within an “ADD COLUMN” operation. The DDL
    compiler is now consulted for inline constraints within the
    Operations.add_column() method as is done for regular CREATE TABLE
    operations. References: #655

Sat Feb  8 20:39:12 UTC 2020 - Arun Persaud <>

- update to version 1.4.0:
  * feature
    + Added new parameters BatchOperations.add_column.insert_before,
      BatchOperations.add_column.insert_after which provide for
      establishing the specific position in which a new column should
      be placed. Also added
      Operations.batch_alter_table.partial_reordering which allows the
      complete set of columns to be reordered when the new table is
      created. Both operations apply only to when batch mode is
      recreating the whole table using recreate="always". Thanks to
      Marcin Szymanski for assistance with the implementation.
      References: #640
  * bug
    + Adjusted the unique constraint comparison logic in a similar
      manner as that of #421 did for indexes in order to take into
      account SQLAlchemy’s own truncation of long constraint names
      when a naming convention is in use. Without this step, a name
      that is truncated by SQLAlchemy based on a unique constraint
      naming convention or hardcoded name will not compare properly.
      References: #647
    + A major rework of the “type comparison” logic is in place which
      changes the entire approach by which column datatypes are
      compared. Types are now compared based on the DDL string
      generated by the metadata type vs. the datatype reflected from
      the database. This means we compare types based on what would
      actually render and additionally if elements of the types change
      like string length, those changes are detected as well. False
      positives like those generated between SQLAlchemy Boolean and
      MySQL TINYINT should also be resolved. Thanks very much to Paul
      Becotte for lots of hard work and patience on this one.  See
      also: What does Autogenerate Detect (and what does it not
      detect?) - updated comments on type comparison References: #605
  * usecase
    + Moved the use of the __file__ attribute at the base of the
      Alembic package into the one place that it is specifically
      needed, which is when the config attempts to locate the template
      directory. This helps to allow Alembic to be fully importable in
      environments that are using Python memory-only import
      schemes. Pull request courtesy layday.  References: #648
  * misc
    + The internal inspection routines no longer use SQLAlchemy’s
      Inspector.from_engine() method, which is expected to be
      deprecated in 1.4. The inspect() function is now used.

- update to version 1.3.3:
  * bug
    + Fixed issue where COMMENT directives for PostgreSQL failed to
      correctly include an explicit schema name, as well as correct
      quoting rules for schema, table, and column names. Pull request
      courtesy Matthew Sills.  References: #637
  * usecase
    + Added support for rendering of “computed” elements on Column
      objects, supported in SQLAlchemy via the new Computed element
      introduced in version 1.3.11. Pull request courtesy Federico
      Note that there is currently no support for ALTER COLUMN to add,
      remove, or modify the “GENERATED ALWAYS AS” element from a
      column; at least for PostgreSQL, it does not seem to be
      supported by the database. Additionally, SQLAlchemy does not
      currently reliably reflect the “GENERATED ALWAYS AS” phrase from
      an existing column, so there is also no autogenerate support for
      addition or removal of the Computed element to or from an
      existing column, there is only support for adding new columns
      that include the Computed element. In the case that the Computed
      element is removed from the Column object in the table metadata,
      PostgreSQL and Oracle currently reflect the “GENERATED ALWAYS
      AS” expression as the “server default” which will produce an op
      that tries to drop the element as a default. References: #624

Sun Dec 29 21:12:46 UTC 2019 - Arun Persaud <>

- update to version 1.3.2:
  * bug
    + [bug] [api] [autogenerate]Fixed regression introduced by #579
      where server default rendering functions began to require a
      dialect implementation, however the render_python_code()
      convenience function did not include one, thus causing the
      function to fail when used in a server default context. The
      function now accepts a migration context argument and also
      creates one against the default dialect if one is not
      provided.References: #635

      the location of the alembic configuration script in lieu of
      using the -c command line option.  References: #608
  * bug
    + Fixed bug in new Variant autogenerate where the order of the
      arguments to Variant were mistakenly reversed.  References: #131
  * misc
    + Some internal modifications have been made to how the names of
      indexes and unique constraints work to make use of new functions
      added in SQLAlchemy 1.4, so that SQLAlchemy has more flexibility
      over how naming conventions may be applied to these objects.

Wed Sep 25 03:19:44 UTC 2019 - Thomas Bechtold <>

- update to 1.2.1:
  * bugs
    + Reverted the name change of the “revisions” argument to
      command.stamp() to “revision” as apparently applications are
      calling upon this argument as a keyword name. Pull request
      courtesy Thomas Bechtold. Special translations are also added
      to the command line interface so that it is still known
      as “revisions” in the CLI.
      References: #601
    + Removed the “test requirements” from “ test”, as
      this command now only emits a removal error in any case
      and these requirements are unused.

Sat Sep 21 19:10:16 UTC 2019 - Arun Persaud <>

- update to version 1.2.0:
  * feature
    + Added new --purge flag to the alembic stamp command, which will
      unconditionally erase the version table before stamping
      anything. This is useful for development where non-existent
      version identifiers might be left within the table. Additionally,
      alembic.stamp now supports a list of revision identifiers, which
      are intended to allow setting up muliple heads at once. Overall
      handling of version identifiers within the alembic.stamp command
      has been improved with many new tests and use cases added.
      References: #473
    + Added new feature MigrationContext.autocommit_block(), a special
      directive which will provide for a non-transactional block inside
      of a migration script. The feature requres that: the database
      driver (e.g. DBAPI) supports the AUTOCOMMIT isolation mode. The
      directive also necessarily needs to COMMIT the existing
      transaction in progress in order to enter autocommit mode.  See
      also MigrationContext.autocommit_block() References: #123
      + Added “post write hooks” to revision generation. These allow
      custom logic to run after a revision Python script is generated,
      typically for the purpose of running code formatters such as
      “Black” or “autopep8”, but may be used for any arbitrary
      post-render hook as well, including custom Python functions or
      scripts. The hooks are enabled by providing a [post_write_hooks]
      section in the alembic.ini file. A single hook is provided which
      runs an arbitrary Python executable on the newly generated
      revision script, which can be configured to run code formatters
      such as Black; full examples are included in the documentation.
      See also Applying Post Processing and Python Code Formatters to
      Generated Revisions References: #307
    + Added new flag --package to alembic init. For environments where
      the Alembic migration files and such are within the package tree
      and importable as modules, this flag can be specified which will
      add the additional files in the version location and
      the environment location.  References: #463
  * bug
    + Improved the Python rendering of a series of migration
      operations such that a single “pass” is rendered for a
      UpgradeOps or DowngradeOps based on if no lines of Python code
      actually rendered under the operation, rather than whether or
      not sub-directives exist. Removed extra “pass” lines that would
      generate from the ModifyTableOps directive so that these aren’t
      duplicated under operation rewriting scenarios.  References:
    + Fixed bug where rendering of comment text for table-level
      comments within Operations.create_table_comment() and
      Operations.drop_table_comment() was not properly quote-escaped
      within rendered Python code for autogenerate.  References: #549
    + Modified the logic of the Rewriter object such that it keeps a
      memoization of which directives it has processed, so that it can
      ensure it processes a particular directive only once, and
      additionally fixed Rewriter so that it functions correctly for
      multiple-pass autogenerate schemes, such as the one illustrated
      in the “multidb” template. By tracking which directives have
      been processed, a multiple-pass scheme which calls upon the
      Rewriter multiple times for the same structure as elements are
      added can work without running duplicate operations on the same
      elements more than once.  References: #505
  * usecase
    + Added autogenerate support for Column objects that have
      dialect-specific **kwargs, support first added in SQLAlchemy
      1.3. This includes SQLite “on conflict” as well as options used
      by some third party dialects.  References: #518
    + Added rendering for SQLAlchemy Variant datatypes, which render
      as the base type plus one or more .with_variant() method calls.
      References: #131
    + Made the command interface revision lookup behavior more strict
      in that an Alembic revision number is only resolved based on a
      partial match rules if it has at least four characters, to
      prevent simple typographical issues from inadvertently running
      migrations.  References: #534
  * misc
    + Python 3.4 support is dropped, as the upstream tooling (pip,
      mysqlclient) etc are already dropping support for Python 3.4,
      which itself is no longer maintained.

  * increased min version of SQLAlechmy

- update to version 1.1.0:
  * bug
    + Fixed bug where the double-percent logic applied to some
      dialects such as psycopg2 would be rendered in --sql mode, by
      allowing dialect options to be passed through to the dialect
      used to generate SQL and then providing paramstyle="named" so
      that percent signs need not be doubled. For users having this
      issue, existing scripts need to add
      dialect_opts={"paramstyle": "named"} to their offline
      context.configure(). See the alembic/templates/generic/
      template for an example.  References: #562
    + Fixed use of the deprecated “imp” module, which is used to
      detect pep3147 availability as well as to locate .pyc files,
      which started emitting deprecation warnings during the test
      suite. The warnings were not being emitted earlier during the
      test suite, the change is possibly due to changes in py.test
      itself but this is not clear. The check for pep3147 is set to
      True for any Python version 3.5 or greater now and importlib is
      used when available. Note that some dependencies such as
      distutils may still be emitting this warning. Tests are adjusted
      to accommodate for dependencies that emit the warning as well.
    + Fixed issue where emitting a change of column name for MySQL did
      not preserve the column comment, even if it were specified as
      existing_comment.  References: #594
    + Removed the “python test” feature in favor of a
      straight run of “tox”. Per Pypa / pytest developers, “”
      commands are in general headed towards deprecation in favor of
      tox. The tox.ini script has been updated such that running “tox”
      with no arguments will perform a single run of the test suite
      against the default installed Python interpreter.  See also
      References: #592
  * usecase
    + The “alembic init” command will now proceed if the target
      directory exists as long as it’s still empty. Previously, it
      would not proceed if the directory existed. The new behavior is
      modeled from what git does, to accommodate for container or
      other deployments where an Alembic target directory may need to
      be already mounted instead of being created with alembic
      init. Pull request courtesy Aviskar KC.  References: #571
  * misc
    + Alembic 1.1 bumps the minimum version of SQLAlchemy to 1.1. As
      was the case before, Python requirements remain at Python 2.7,
      or in the 3.x series Python 3.4.
    + The test suite for Alembic now makes use of SQLAlchemy’s testing
      framework directly. Previously, Alembic had its own version of
      this framework that was mostly copied from that of SQLAlchemy to
      enable testing with older SQLAlchemy versions. The majority of
      this code is now removed so that both projects can leverage
      improvements from a common testing framework.

Sat Jul  6 21:27:43 UTC 2019 - Arun Persaud <>

- update to version 1.0.11:
  * bug
    + SQLite server default reflection will ensure parenthesis are
      surrounding a column default expression that is detected as
      being a non-constant expression, such as a datetime() default,
      to accommodate for the requirement that SQL expressions have to
      be parenthesized when being sent as DDL. Parenthesis are not
      added to constant expressions to allow for maximum
      cross-compatibility with other dialects and existing test suites
      (such as Alembic’s), which necessarily entails scanning the
      expression to eliminate for constant numeric and string
      values. The logic is added to the two “reflection->DDL round
      trip” paths which are currently autogenerate and batch
      migration. Within autogenerate, the logic is on the rendering
      side, whereas in batch the logic is installed as a column
      reflection hook.  References: #579
    + Improved SQLite server default comparison to accommodate for a
      text() construct that added parenthesis directly vs. a construct
      that relied upon the SQLAlchemy SQLite dialect to render the
      parenthesis, as well as improved support for various forms of
      constant expressions such as values that are quoted
      vs. non-quoted.  References: #579
    + Fixed bug where the “literal_binds” flag was not being set when
      autogenerate would create a server default value, meaning server
      default comparisons would fail for functions that contained
      literal values.
    + Added support for MySQL “DROP CHECK”, which is added as of MySQL
      8.0.16, separate from MariaDB’s “DROP CONSTRAINT” for CHECK
      constraints. The MySQL Alembic implementation now checks for
      “MariaDB” in server_version_info to decide which one to use.
      References: #554
    + Fixed issue where MySQL databases need to use CHANGE COLUMN when
      altering a server default of CURRENT_TIMESTAMP, NOW() and
      probably other functions that are only usable with
      DATETIME/TIMESTAMP columns. While MariaDB supports both CHANGE
      and ALTER COLUMN in this case, MySQL databases only support
      CHANGE. So the new logic is that if the server default change is
      against a DateTime-oriented column, the CHANGE format is used
      unconditionally, as in the vast majority of cases the server
      default is to be CURRENT_TIMESTAMP which may also be potentially
      bundled with an “ON UPDATE CURRENT_TIMESTAMP” directive, which
      SQLAlchemy does not currently support as a distinct field. The
      fix addiionally improves the server default comparison logic
      when the “ON UPDATE” clause is present and there are parenthesis
      to be adjusted for as is the case on some MariaDB versions.

    + Warnings emitted by Alembic now include a default stack level of

    + Replaced the Python compatbility routines for getargspec() with
      a fully vendored version based on getfullargspec() from Python
      3.3. Originally, Python was emitting deprecation warnings for
      this function in Python 3.8 alphas. While this change was
      reverted, it was observed that Python 3 implementations for
      getfullargspec() are an order of magnitude slower as of the 3.4
      series where it was rewritten against Signature. While Python
      plans to improve upon this situation, SQLAlchemy projects for
      now are using a simple replacement to avoid any future issues.

- update to version 0.9.8:
  * [bug] [runtime] Fixed bug where the Script.as_revision_number()
    method did not accommodate for the ‘heads’ identifier, which in
    turn caused the EnvironmentContext.get_head_revisions() and
    EnvironmentContext.get_revision_argument() methods to be not
    usable when multiple heads were present. The
    :meth:.`EnvironmentContext.get_head_revisions` method returns a
    tuple in all cases as documented. References: #482
  * [bug] [autogenerate] [postgresql] Fixed bug where autogenerate of
    ExcludeConstraint would render a raw quoted name for a Column that
    has case-sensitive characters, which when invoked as an inline
    member of the Table would produce a stack trace that the quoted
    name is not found. An incoming Column object is now rendered as
    sa.column('name'). References: #478
  * [bug] [autogenerate] Fixed bug where the indexes would not be
    included in a migration that was dropping the owning table. The
    fix now will also emit DROP INDEX for the indexes ahead of time,
    but more importantly will include CREATE INDEX in the downgrade
    migration. References: #468
  * [bug] [postgresql] Fixed the autogenerate of the module prefix
    when rendering the text_type parameter of postgresql.HSTORE, in
    much the same way that we do for ARRAY’s type and JSON’s
    text_type. References: #480
  * [bug] [mysql] Added support for DROP CONSTRAINT to the MySQL
    Alembic dialect to support MariaDB 10.2 which now has real CHECK
    constraints. Note this change does not add autogenerate support,
    only support for op.drop_constraint() to work. References: #479

- update to version 0.9.7:
  * [bug] [autogenerate] Fixed regression caused by #421 which would
    cause case-sensitive quoting rules to interfere with the
    comparison logic for index names, thus causing indexes to show as
    added for indexes that have case-sensitive names. Works with
    SQLAlchemy 0.9 and later series.
  * [bug] [autogenerate] [postgresql] Fixed bug where autogenerate
    would produce a DROP statement for the index implicitly created by
    a Postgresql EXCLUDE constraint, rather than skipping it as is the
    case for indexes implicitly generated by unique constraints. Makes
    use of SQLAlchemy 1.0.x’s improved “duplicates index” metadata and
    requires at least SQLAlchemy version 1.0.x to function correctly.

    which adds the correct module import to the “inner” type for an
    ARRAY type, the fix now accommodates for the generic
    sqlalchemy.types.ARRAY type added in SQLAlchemy 1.1, rendering the
    inner type correctly regardless of whether or not the Postgresql
    dialect is present.  References: #442
  * [bug] [mysql] Fixed bug where server default comparison of
    CURRENT_TIMESTAMP would fail on MariaDB 10.2 due to a change in
    how the function is represented by the database during reflection.
    References: #455
  * [bug] [autogenerate] Fixed bug where comparison of Numeric types
    would produce a difference if the Python-side Numeric
    inadvertently specified a non-None “scale” with a “precision” of
    None, even though this Numeric type will pass over the “scale”
    argument when rendering. Pull request courtesy Ivan Mmelnychuk.
    References: pull request bitbucket:70
  * [bug] [batch] The name of the temporary table in batch mode is now
    generated off of the original table name itself, to avoid
    conflicts for the unusual case of multiple batch operations
    running against the same database schema at the same time.
    References: #457
  * [bug] [autogenerate] A ForeignKeyConstraint can now render
    correctly if the link_to_name flag is set, as it will not attempt
    to resolve the name from a “key” in this case. Additionally, the
    constraint will render as-is even if the remote column name isn’t
    present on the referenced remote table.  References: #456
  * [bug] [runtime] [py3k] Reworked “sourceless” system to be fully
    capable of handling any combination of: Python2/3x, pep3149 or
    not, PYTHONOPTIMIZE or not, for locating and loading both
    files as well as versioning files. This includes: locating files
    inside of __pycache__ as well as listing out version files that
    might be only in versions/__pycache__, deduplicating version files
    that may be in versions/__pycache__ and versions/ at the same
    time, correctly looking for .pyc or .pyo files based on if pep488
    is present or not. The latest Python3x deprecation warnings
    involving importlib are also corrected.

  * various bugfixes

Mon Aug 15 10:24:57 UTC 2016 -

- update to 0.8.7:
  - Fixed bug where upgrading to the head of a branch which is already
    present would fail, only if that head were also the dependency
    of a different branch that is also upgraded, as the revision system
    would see this as trying to go in the wrong direction.   The check
    here has been refined to distinguish between same-branch revisions
    out of order vs. movement along sibling branches.
  - Adjusted the version traversal on downgrade
    such that we can downgrade to a version that is a dependency for
    a version in a different branch, *without* needing to remove that
    dependent version as well.  Previously, the target version would be
    seen as a "merge point" for it's normal up-revision as well as the
    dependency.  This integrates with the changes for :ticket:`377`
    and :ticket:`378` to improve treatment of branches with dependencies
  - Fixed bug where a downgrade to a version that is also a dependency
    to a different branch would fail, as the system attempted to treat
    this as an "unmerge" of a merge point, when in fact it doesn't have
    the other side of the merge point available for update.
  - Fixed bug where the "alembic current" command wouldn't show a revision
    as a current head if it were also a dependency of a version in a
    different branch that's also applied.   Extra logic is added to
    extract "implied" versions of different branches from the top-level
    versions listed in the alembic_version table.
  - Fixed bug where a repr() or str() of a Script object would fail
    if the script had multiple dependencies.
  - Fixed bug in autogen where if the DB connection sends the default
    schema as "None", this "None" would be removed from the list of
    schemas to check if include_schemas were set.  This could possibly
    impact using include_schemas with SQLite.
  - Small adjustment made to the batch handling for reflected CHECK
    constraints to accommodate for SQLAlchemy 1.1 now reflecting these.
    Batch mode still does not support CHECK constraints from the reflected
    table as these can't be easily differentiated from the ones created
    by types such as Boolean.

Mon Jun  6 12:56:49 UTC 2016 -

- fix source url

Fri Jun  3 16:37:33 UTC 2016 -

- update to 0.8.6:
  - Errors which occur within the Mako render step are now intercepted
    and raised as CommandErrors like other failure cases; the Mako
    exception itself is written using template-line formatting to
    a temporary file which is named in the exception message.
  - Added a fix to Postgresql server default comparison which first checks
    if the text of the default is identical to the original, before attempting
    to actually run the default.  This accomodates for default-generation
    functions that generate a new value each time such as a uuid function.
  - Fixed bug introduced by the fix for :ticket:`338` in version 0.8.4
    where a server default could no longer be dropped in batch mode.
    Pull request courtesy Martin Domke.
  - Fixed bug where SQL Server arguments for drop_column() would not
    be propagated when running under a batch block.  Pull request
    courtesy Michal Petrucha.

Thu Apr  7 06:24:53 UTC 2016 -

- update to 0.8.5:
  - Fixed bug where the columns rendered in a ``PrimaryKeyConstraint``
    in autogenerate would inappropriately render the "key" of the
    column, not the name.  Pull request courtesy Jesse Dhillon.
  - Repaired batch migration support for "schema" types which generate
    constraints, in particular the ``Boolean`` datatype which generates
    a CHECK constraint.  Previously, an alter column operation with this
    type would fail to correctly accommodate for the CHECK constraint
    on change both from and to this type.  In the former case the operation
    would fail entirely, in the latter, the CHECK constraint would
    not get generated.  Both of these issues are repaired.
  - Changing a schema type such as ``Boolean`` to a non-schema type would
    emit a drop constraint operation which emits ``NotImplementedError`` for
    the MySQL dialect.  This drop constraint operation is now skipped when
    the constraint originates from a schema type.
  - A major improvement to the hash id generation function, which for some
    reason used an awkward arithmetic formula against uuid4() that produced
    values that tended to start with the digits 1-4.  Replaced with a
    simple substring approach which provides an even distribution.  Pull
    request courtesy Antti Haapala.
  - Added an autogenerate renderer for the :class:`.ExecuteSQLOp` operation
    object; only renders if given a plain SQL string, otherwise raises
    NotImplementedError.  Can be of help with custom autogenerate
    sequences that includes straight SQL execution.  Pull request courtesy
    Jacob Magnusson.
  - Batch mode generates a FOREIGN KEY constraint that is self-referential
    using the ultimate table name, rather than ``_alembic_batch_temp``.
    When the table is renamed from ``_alembic_batch_temp`` back to the
    original name, the FK now points to the right name.  This
    will **not** work if referential integrity is being enforced (eg. SQLite
    "PRAGMA FOREIGN_KEYS=ON") since the original table is dropped and
    the new table then renamed to that name, however this is now consistent
    with how foreign key constraints on **other** tables already operate
    with batch mode; these don't support batch mode if referential integrity
    is enabled in any case.
  - Added a type-level comparator that distinguishes :class:`.Integer`,
    :class:`.BigInteger`, and :class:`.SmallInteger` types and
    dialect-specific types; these all have "Integer" affinity so previously
    all compared as the same.
  - Fixed bug where the ``server_default`` parameter of ``alter_column()``
    would not function correctly in batch mode.
  - Adjusted the rendering for index expressions such that a :class:`.Column`
    object present in the source :class:`.Index` will not be rendered
    as table-qualified; e.g. the column name will be rendered alone.
    Table-qualified names here were failing on systems such as Postgresql.
  - Fixed an 0.8 regression whereby the "imports" dictionary member of
    the autogen context was removed; this collection is documented in the
    "render custom type" documentation as a place to add new imports.
    The member is now known as
    :attr:`.AutogenContext.imports` and the documentation is repaired.
  - Fixed bug in batch mode where a table that had pre-existing indexes
    would create the same index on the new table with the same name,
    which on SQLite produces a naming conflict as index names are in a
    global namespace on that backend.   Batch mode now defers the production
    of both existing and new indexes until after the entire table transfer
    operation is complete, which also means those indexes no longer take
    effect during the INSERT from SELECT section as well; the indexes
    are applied in a single step afterwards.
  - Added "pytest-xdist" as a tox dependency, so that the -n flag
    in the test command works if this is not already installed.
    Pull request courtesy Julien Danjou.
  - Fixed issue in PG server default comparison where model-side defaults
    configured with Python unicode literals would leak the "u" character
    from a ``repr()`` into the SQL used for comparison, creating an invalid
    SQL expression, as the server-side comparison feature in PG currently
    repurposes the autogenerate Python rendering feature to get a quoted
    version of a plain string default.

Wed Aug 26 14:34:12 UTC 2015 -

- update to 0.8.2:
  - Added workaround in new foreign key option detection feature for MySQL’s
    consideration of the “RESTRICT” option being the default, for which no
    value is reported from the database; the MySQL impl now corrects for when
    the model reports RESTRICT but the database reports nothing. A similar
    rule is in the default FK comparison to accommodate for the default
    “NO ACTION” setting being present in the model but not necessarily
    reported by the database, or vice versa.
  - A custom EnvironmentContext.configure.process_revision_directives hook
    can now generate op directives within the UpgradeOps and DowngradeOps
    containers that will be generated as Python code even when the
    --autogenerate flag is False; provided that revision_environment=True,
    the full render operation will be run even in “offline” mode.
  - Implemented support for autogenerate detection of changes in the ondelete,
    onupdate, initially and deferrable attributes of ForeignKeyConstraint
    objects on SQLAlchemy backends that support these on reflection (as of
    SQLAlchemy 1.0.8 currently Postgresql for all four, MySQL for ondelete
    and onupdate only). A constraint object that modifies these values will
    be reported as a “diff” and come out as a drop/create of the constraint
    with the modified values. The fields are ignored for backends which
    don’t reflect these attributes (as of SQLA 1.0.8 this includes SQLite,
    Oracle, SQL Server, others).
  - Repaired the render operation for the ops.AlterColumnOp object to succeed
  when the “existing_type” field was not present.
  - Fixed a regression 0.8 whereby the “multidb” environment template failed
  to produce independent migration script segments for the output template.
  This was due to the reorganization of the script rendering system for 0.8.
  To accommodate this change, the MigrationScript structure will in the case
  of multiple calls to MigrationContext.run_migrations() produce lists for
  the MigrationScript.upgrade_ops and MigrationScript.downgrade_ops attributes;
  each UpgradeOps and DowngradeOps instance keeps track of its own upgrade_token
  and downgrade_token, and each are rendered individually.

Fri Aug 21 12:05:28 UTC 2015 -

- update to 0.8.0:
  - Added new command alembic edit. This command takes the same arguments
    as alembic show, however runs the target script file within $EDITOR.
    Makes use of the python-editor library in order to facilitate the
    handling of $EDITOR with reasonable default behaviors across platforms.
    Pull request courtesy Michel Albert.
  - Added new multiple-capable argument --depends-on to the alembic revision
    command, allowing depends_on to be established at the command line level
    rather than having to edit the file after the fact. depends_on identifiers
    may also be specified as branch names at the command line or directly
    within the migration file. The values may be specified as partial
    revision numbers from the command line which will be resolved to full
    revision numbers in the output file.
  - The default test runner via “python test” is now py.test.

    extensible system of operation objects present in #302. As part of this

    of migration scripts to be written as well as operation objects that will
    render all the Python code within them; a new hook
    EnvironmentContext.configure.process_revision_directives allows end-user
    code to fully customize what autogenerate will do, including not just
    full manipulation of the Python steps to take but also what file or files
    will be written and where. Additionally, autogenerate is now extensible as
    far as database objects compared and rendered into scripts; any new
    operation directive can also be registered into a series of hooks that
    allow custom database/model comparison functions to run as well as to
    render new operation directives into autogenerate scripts.
  - Fixed bug in batch mode where the batch_op.create_foreign_key() directive
    would be incorrectly rendered with the source table and schema names in
    the argument list.
  - Fixed bug where in the erroneous case that alembic_version contains
    duplicate revisions, some commands would fail to process the version history
    correctly and end up with a KeyError. The fix allows the versioning logic
    to proceed, however a clear error is emitted later when attempting to
    update the alembic_version table.
  - Implemented support for BatchOperations.create_primary_key() and
    BatchOperations.create_check_constraint(). Additionally, table keyword
    arguments are copied from the original reflected table, such as the
    “mysql_engine” keyword argument.
  - Fixed critical issue where a complex series of branches/merges would
    bog down the iteration algorithm working over redundant nodes for millions
    of cycles. An internal adjustment has been made so that duplicate nodes are
    skipped within this iteration.
  - The MigrationContext.stamp() method, added as part of the versioning
    refactor in 0.7 as a more granular version of command.stamp(), now includes
    the “create the alembic_version table if not present” step in the same
    way as the command version, which was previously omitted.
  - Fixed bug where foreign key options including “onupdate”, “ondelete” would
    not render within the op.create_foreign_key() directive, even though they
    render within a full ForeignKeyConstraint directive.
  - Repaired warnings that occur when running unit tests against SQLAlchemy
    1.0.5 or greater involving the “legacy_schema_aliasing” flag.
- Add python-pytest-cov as BuildRequires
- Add python-python-editor as Requires and BuildRequires

  * Fixed bug where the case of multiple mergepoints that all
    have the identical set of ancestor revisions would fail to be
    upgradable, producing an assertion failure.
  * Added support for type comparison functions to be not just per
    environment, but also present on the custom types themselves, by
    supplying a method ``compare_against_backend``.
  * Fully implemented the :paramref:`~.Operations.batch_alter_table.copy_from`

    directive, which was mis-named internally such that the operation

Sat Apr 25 15:53:02 UTC 2015 -

- update to 0.7.5.post2:
  * Added a new feature Config.attributes, to help with the use
    case of sharing state such as engines and connections on the
    outside with a series of Alembic API calls; also added a new
    cookbook section to describe this simple but pretty important
    use case.
  * The format of the default script has been refined a bit;
    it now uses context managers not only for the scope of the
    transaction, but also for connectivity from the starting
    engine. The engine is also now called a “connectable” in
    support of the use case of an external connection being passed
  * Added support for “alembic stamp” to work when given “heads” as
    an argument, when multiple heads are present.
  * The --autogenerate option is not valid when used in conjunction
    with “offline” mode, e.g. --sql. This now raises a
    CommandError, rather than failing more deeply later on. Pull
    request courtesy Johannes Erdfelt.
  * Fixed bug where the mssql DROP COLUMN directive failed to
    include modifiers such as “schema” when emitting the DDL.
  * Postgresql “functional” indexes are necessarily skipped from
    the autogenerate process, as the SQLAlchemy backend currently
    does not support reflection of these structures. A warning is
    emitted both from the SQLAlchemy backend as well as from the
    Alembic backend for Postgresql when such an index is detected.
  * Fixed bug where MySQL backend would report dropped unique
    indexes and/or constraints as both at the same time. This is
    because MySQL doesn’t actually have a “unique constraint”
    construct that reports differently than a “unique index”, so it
    is present in both lists. The net effect though is that the
    MySQL backend will report a dropped unique index/constraint as
    an index in cases where the object was first created as a
    unique constraint, if no other information is available to make
    the decision. This differs from other backends like Postgresql
    which can report on unique constraints and unique indexes
  * Fixed bug where using a partial revision identifier as the
    “starting revision” in --sql mode in a downgrade operation
    would fail to resolve properly.
- set minimum version for SQLAlchemy to 0.7.6

Thu Feb  5 15:04:20 UTC 2015 -

- update to 0.7.4:
  * Repaired issue where a server default specified without text()
  that represented a numeric or floating point (e.g. with decimal
  places) value would fail in the Postgresql-specific check for
  “compare server default”; as PG accepts the value with quotes
  in the table specification, it’s still valid. Pull request
  courtesy Dimitris Theodorou.
  * The rendering of a ForeignKeyConstraint will now ensure that
  the names of the source and target columns are the database-side
  name of each column, and not the value of the .key attribute as
  may be set only on the Python side. This is because Alembic
  generates the DDL for constraints as standalone objects without
  the need to actually refer to an in-Python Table object, so
  there’s no step that would resolve these Python-only key names
  to database column names.
  * Fixed bug in foreign key autogenerate where if the in-Python
  table used custom column keys (e.g. using the key='foo' kwarg
  to Column), the comparison of existing foreign keys to those
  specified in the metadata would fail, as the reflected table
  would not have these keys available which to match up. Foreign
  key comparison for autogenerate now ensures it’s looking at
  the database-side names of the columns in all cases; this
  matches the same functionality within unique constraints and
  * Fixed issue in autogenerate type rendering where types that
  belong to modules that have the name “sqlalchemy” in them would
  be mistaken as being part of the sqlalchemy. namespace. Pull
  req courtesy Bartosz Burclaf.

Mon Jan  5 10:19:27 UTC 2015 -

- update to 0.7.3:
  * Fixed regression in new versioning system where upgrade / history
  operation would fail on AttributeError if no version files were
  present at all.
  * Adjusted the SQLite backend regarding autogen of unique constraints
  to work fully with the current SQLAlchemy 1.0, which now will report
  on UNIQUE constraints that have no name.
  * Fixed bug in batch where if the target table contained multiple
  foreign keys to the same target table, the batch mechanics would
  fail with a "table already exists" error.  Thanks for the help
  on this from Lucas Kahlert.
  * Fixed an issue where the MySQL routine to skip foreign-key-implicit
  indexes would also catch unnamed unique indexes, as they would be
  named after the column and look like the FK indexes.  Pull request
  courtesy Johannes Erdfelt.
  * Repaired a regression in both the MSSQL and Oracle dialects whereby
  the overridden ``_exec()`` method failed to return a value, as is
  needed now in the 0.7 series.
  * The ``render_as_batch`` flag was inadvertently hardcoded to ``True``,
  so all autogenerates were spitting out batch mode...this has been
  fixed so that batch mode again is only when selected in
  * Support for autogenerate of FOREIGN KEY constraints has been added.
  These are delivered within the autogenerate process in the same
  manner as UNIQUE constraints, including ``include_object`` support.
  Big thanks to Ann Kamyshnikova for doing the heavy lifting here.
  * Fixed bug where the "source_schema" argument was not correctly passed
  when calling :meth:`.BatchOperations.create_foreign_key`.  Pull
  request courtesy Malte Marquarding.
  * The "multiple heads / branches" feature has now landed.  This is
  by far the most significant change Alembic has seen since its inception;
  while the workflow of most commands hasn't changed, and the format
  of version files and the ``alembic_version`` table are unchanged as well,
  a new suite of features opens up in the case where multiple version
  files refer to the same parent, or to the "base".  Merging of
  branches, operating across distinct named heads, and multiple
  independent bases are now all supported.   The feature incurs radical
  changes to the internals of versioning and traversal, and should be
  treated as "beta mode" for the next several subsequent releases
  within 0.7.
  * Added "move and copy" workflow, where a table to be altered is copied to
  a new one with the new structure and the old one dropped, is now
  implemented for SQLite as well as all database backends in general
  using the new :meth:`.Operations.batch_alter_table` system.   This
  directive provides a table-specific operations context which gathers
  column- and constraint-level mutations specific to that table, and
  at the end of the context creates a new table combining the structure
  of the old one with the given changes, copies data from old table to new,
  and finally drops the old table,
  renaming the new one to the existing name.  This is required for
  fully featured SQLite migrations, as SQLite has very little support for the
  traditional ALTER directive.   The batch directive
  is intended to produce code that is still compatible with other databases,
  in that the "move and copy" process only occurs for SQLite by default,
  while still providing some level of sanity to SQLite's
  requirement by allowing multiple table mutation operations to
  proceed within one "move and copy" as well as providing explicit
  control over when this operation actually occurs.  The "move and copy"
  feature may be optionally applied to other backends as well, however
  dealing with referential integrity constraints from other tables must
  still be handled explicitly.
  * Relative revision identifiers as used with ``alembic upgrade``,
  ``alembic downgrade`` and ``alembic history`` can be combined with
  specific revisions as well, e.g. ``alembic upgrade ae10+3``, to produce
  a migration target relative to the given exact version.

Mon Sep 15 05:25:46 UTC 2014 -

- update to version 0.6.7:
  * See
  * Fixed bug in MSSQL dialect where "rename table" wasn't using
    ``sp_rename()`` as is required on SQL Server.  Pull request courtesy
  * Added support for functional indexes when using the
    :meth:`.Operations.create_index` directive.   Within the list of columns,
    the SQLAlchemy ``text()`` construct can be sent, embedding a literal
    SQL expression; the :meth:`.Operations.create_index` will perform some
    hackery behind the scenes to get the :class:`.Index` construct to cooperate.
    This works around some current limitations in :class:`.Index`
    which should be resolved on the SQLAlchemy side at some point.
  * A file named ```` in the ``versions/`` directory is now
    ignored by Alembic when the collection of version files is retrieved.
    Pull request courtesy Michael Floering.
  * Fixed Py3K bug where an attempt would be made to sort None against
    string values when autogenerate would detect tables across multiple
    schemas, including the default schema.  Pull request courtesy
  * Autogenerate render will render the arguments within a Table construct
    using ``*[...]`` when the number of columns/elements is greater than
    255.  Pull request courtesy Ryan P. Kelly.
  * Fixed bug where foreign key constraints would fail to render in
    autogenerate when a schema name was present.  Pull request courtesy
    Andreas Zeidler.
  * Some deep-in-the-weeds fixes to try to get "server default" comparison
    working better across platforms and expressions, in particular on
    the Postgresql backend, mostly dealing with quoting/not quoting of various
    expressions at the appropriate time and on a per-backend basis.
    Repaired and tested support for such defaults as Postgresql interval
    and array defaults.
  * When a run of Alembic command line fails due to ``CommandError``,
    the output now prefixes the string with ``"FAILED:"``, and the error
    is also written to the log output using ``log.error()``.
  * Liberalized even more the check for MySQL indexes that shouldn't be
    counted in autogenerate as "drops"; this time it's been reported
    that an implicitly created index might be named the same as a composite
    foreign key constraint, and not the actual columns, so we now skip those
    when detected as well.
  * Added a new accessor :attr:`.MigrationContext.config`, when used
    in conjunction with a :class:`.EnvironmentContext` and
    :class:`.Config`, this config will be returned.  Patch
    courtesy Marc Abramowitz.

Thu Jul 24 11:33:27 UTC 2014 -

  * See
  * Added new argument EnvironmentContext.configure.user_module_prefix
  * The ScriptDirectory system that loads migration files from a
    versions/ directory
  * The command.revision() command now returns the Script object
    corresponding to the newly generated revision
  * Added new feature
    EnvironmentContext.configure.transaction_per_migration, which when True
    causes the BEGIN/COMMIT pair to incur for each migration individually

  * [feature] The output of the alembic history command is now expanded.
  * [feature] Added alembic.config.Config.cmd_opts attribute, allows access to the
  argparse options passed to the alembic runner.(link)
  * [feature] Added new command line argument -x, allows extra arguments to be
  appended to the command line which can be consumed within an script by
  looking at context.config.cmd_opts.x, or more simply a new method
  * [feature] Added -r argument to alembic history command, allows specification of [start]:[end] to view a slice of history.
  * [feature] Source base is now in-place for Python 2.6 through 3.3,
  without the need for 2to3.
  * [feature] Added new kw argument to EnvironmentContext.configure() include_object.

Sun Apr 14 15:53:22 UTC 2013 -

- Update to version 0.5.0
  + added version_table_schema argument to EnvironmentContext.configure(),
    complements the version_table argument to set an optional remote schema
    for the version table.
  + added output_encoding option to EnvironmentContext.configure(), used with --sql
    mode to apply an encoding to the output stream.
  + added Operations.create_primary_key() operation, will genenerate an
    ADD CONSTRAINT for a primary key.
  + upgrade and downgrade commands will list the first line of the docstring
    out next to the version number.
  + added –head-only option to “alembic current”, will print current version
    plus the symbol “(head)” if this version is the head or not.
  + the rendering of any construct during autogenerate can be customized, in particular
    to allow special rendering for user-defined column, constraint subclasses, using new render
   _item argument to EnvironmentContext.configure().
  + fix format of RENAME for table that includes schema with Postgresql; the
    schema name shouldn’t be in the “TO” field.
  + fix bug whereby double quoting would be applied to target column name during an sp_rename operation.
  + fix transactional_ddl flag for SQLite, MySQL dialects set to False. MySQL doesn’t support it,
    SQLite does but current pysqlite driver does not.
  + fix Autogenerate will render additional table keyword arguments like “mysql_engine” and
    others within op.create_table().
  + fix bug whereby create_index() would include in the constraint columns that are added
    to all Table objects using events, externally to the generation of the constraint.
    This is the same issue that was fixed for unique constraints in version 0.3.2.
  + fix worked around a backwards-incompatible regression in Python3.3 regarding argparse;
    running “alembic” with no arguments now yields an informative error in py3.3 as with
    all previous versions.
  + fix host of argument name changes within migration operations for consistency. Keyword
    arguments will continue to work on the old name for backwards compatibility, however required
    positional arguments will not:
    * Operations.alter_column() - name -> new_column_name - old name will work for backwards compatibility.
    * Operations.create_index() - tablename -> table_name - argument is positional.
    * Operations.drop_index() - tablename -> table_name - old name will work for backwards compatibility.
    * Operations.drop_constraint() - tablename -> table_name - argument is positional.
    * Operations.drop_constraint() - type -> type_ - old name will work for backwards compatibility
  + SQLAlchemy 0.6 is no longer supported by Alembic - minimum version is 0.7.3, full support is as of 0.7.9.

- Update to version 0.4.2:
  + Fixed bug where autogenerate would fail if a Column to be added to
    a table made use of the ".key" paramter.
  + Added a workaround to to prevent "NoneType" error from
    occuring when " test" is run.
  + Added a README.unittests with instructions for running the test
    suite fully.
- Changes from version 0.4.1:
  + Added support for autogenerate render of ForeignKeyConstraint
    options onupdate, ondelete, initially, and deferred.
  + Explicit error message describing the case when downgrade --sql
    is used without specifying specific start/end versions.
  + Fixed the minute component in file_template
    which returned the month part of the create date.

- Update to version 0.4.0:
  + [feature] Support for tables in alternate schemas
    has been added fully to all operations, as well as to
    the autogenerate feature.  When using autogenerate,
    specifying the flag include_schemas=True to
    Environment.configure() will also cause autogenerate
    to scan all schemas located by Inspector.get_schema_names(),
    which is supported by *some* (but not all)
    SQLAlchemy dialects including Postgresql.
    *Enormous* thanks to Bruno Binet for a huge effort
    in implementing as well as writing tests.  #33.
  + [feature] The command line runner has been organized
    into a reusable CommandLine object, so that other
    front-ends can re-use the argument parsing built
    in.  #70
  + [feature] Added "stdout" option to Config, provides
    control over where the "print" output of commands like
    "history", "init", "current" etc. are sent.  #43
  + [bug] Fixed the "multidb" template which was badly out
    of date.   It now generates revision files using
    the configuration to determine the different
    upgrade_<xyz>() methods needed as well, instead of
    needing to hardcode these.  Huge thanks to
    BryceLohr for doing the heavy lifting here.  #71
  + [bug] Fixed the regexp that was checking for .py files
    in the version directory to allow any .py file through.
    Previously it was doing some kind of defensive checking,
    probably from some early notions of how this directory
    works, that was prohibiting various filename patterns
    such as those which begin with numbers.  #72
  + [bug] Fixed MySQL rendering for server_default which
    didn't work if the server_default was a generated
    SQL expression.  Courtesy Moriyoshi Koizumi.
  + [feature] Added support for alteration of MySQL
    columns that have AUTO_INCREMENT, as well as enabling
    this flag.  Courtesy Moriyoshi Koizumi.

Wed Jun  6 12:13:48 UTC 2012 -

- Update to version 0.3.4:
  + [bug] Fixed command-line bug introduced by the
    "revision_environment" feature.
- Changes from version 0.3.3:
  + [feature] New config argument
    "revision_environment=true", causes to
    be run unconditionally when the "revision" command
    is run, to support templates with
    dependencies on custom "template_args".
  + [feature] Added "template_args" option to configure()
    so that an can add additional arguments
    to the template context when running the
    "revision" command.  This requires either --autogenerate
    or the configuration directive "revision_environment=true".
  + [bug] Added "type" argument to op.drop_constraint(),
    and implemented full constraint drop support for
    MySQL.  CHECK and undefined raise an error.
    MySQL needs the constraint type
    in order to emit a DROP CONSTRAINT. #44
  + [feature] Added version_table argument to
    EnvironmentContext.configure(), allowing for the
    configuration of the version table name. #34
  + [feature] Added support for "relative" migration
    identifiers, i.e. "alembic upgrade +2",
    "alembic downgrade -1".  Courtesy
    Atsushi Odagiri for this feature.
  + [bug] Fixed bug whereby directories inside of
    the template directories, such as __pycache__
    on Pypy, would mistakenly be interpreted as
    files which are part of the template. #49

Wed May 23 12:55:05 UTC 2012 -

- Update to version 0.3.2:
  + [feature] Basic support for Oracle added
  + [feature] Added support for UniqueConstraint in autogenerate
  + [bug] Fixed support of schema-qualified ForeignKey target in column alter operations,
  + [bug] Fixed bug whereby create_unique_constraint() would include in
    the constraint columns that are added to all Table objects using events,
    externally to the generation of the constraint.
- Changes from version 0.3.1:
  + [bug] bulk_insert() fixes:
    1. bulk_insert() operation was not working most likely since the 0.2 series
       when used with an engine
    2. Repaired bulk_insert() to complete when used against a lower-case-t
       table and executing with only one set of parameters, working
       around SQLAlchemy bug #2461 in this regard.
    3. bulk_insert() uses "inline=True" so that phrases like RETURNING and
       such don't get invoked for single-row bulk inserts.
    4. bulk_insert() will check that you're passing a list of dictionaries
       in, raises TypeError if not detected.
- Changes from version 0.3.0:
  + [general] The focus of 0.3 is to clean up and more fully document the
    public API of Alembic, including better accessors on the MigrationContext
    and ScriptDirectory objects.  Methods that are not considered to be
    public on these objects have been underscored, and methods which should
    be public have been cleaned up and documented, including:
  + [feature] Added a bit of autogenerate to the public API in the form of
    the function alembic.autogenerate.compare_metadata.
