- New version 3.1.1
- Fixed a critical bug that caused an exception at import time.
The error was triggered when a bug in long-double detection is detected
in the HDF5 library (see :issue:`275`) and numpy_ does not expose
`float96` or `float128`. Closes :issue:`344`.
- The internal Blosc_ library has been updated to version 1.3.5.
This fixes a false buffer overrun condition that made c-blosc to fail,
even if the problem was not real.
- New version 3.1.0
- New features¶
- Now PyTables is able to save/restore the default value
of EnumAtom types.
- Implemented support for the H5FD_SPLIT driver.
- New quantization filter: the filter truncates floating point
data to a specified precision before writing to disk.
This can significantly improve the performance of compressors.
- Added new VLArray.get_row_size() method to VLArray for querying
the number of atoms of a VLArray row. Closes gh-24 and gh-315.
- The internal Blosc library has been updated to version 1.3.2.
All new features introduced in the Blosc 1.3.x series, and in
particular the ability to leverage different compressors within
Blosc (see the Blosc Release Notes), are now available in
PyTables via the blosc filter.
- Improvements¶
- The node caching mechanism has been completely redesigned to
be simpler and less dependent from specific behaviours of
the __del__ method. Now PyTables is compatible with the
forthcoming Python 3.4. Closes gh-306.
- PyTables no longer uses shared/cached file handlers.
This change somewhat improves support for concurrent reading
allowing the user to safely open the same file in different
threads for reading (requires HDF5 >= 1.8.7). More details
about this change can be found in the Backward incompatible
changes section. See also gh-130, gh-129 gh-292 and gh-216.
- PyTables is now able to detect and use external installations
of the Blosc library (closes gh-104). If Blosc is not found in
the system, and the user do not specify a custom installation
directory, then it is used an internal copy of the Blosc source
code.
- Automatically disable extended float support if a buggy version
of HDF5 is detected (see also Issues with H5T_NATIVE_LDOUBLE).
- Documented an unexpected behaviour with string literals in query
conditions on Python 3 (closes gh-265)
- The deprecated getopt module has been dropped in favour of
argparse in all command line utilities (close gh-251)
- Improved the installation section of the PyTables User’s Guide.
- instructions for installing PyTables via pip have been added.
- added a reference to the Anaconda, Canopy and Christoph
Gohlke suites (closes gh-291)
- Enabled Travis-CI builds for Python 3.3
- Tables.read_coordinates() now also works with boolean indices input.
- Improved compatibility with numpy >= 1.8 (see gh-259)
- The code of the benchmark programs (bench directory) has been updated.
- Fixed some warning related to non-unicode file names
(the Windows bytes API has been deprecated in Python 3.4)
- Bugs fixed¶
- Fixed detection of platforms supporting Blosc
- Fixed a crash that occurred when one attempts to write a numpy array
to an Atom (closes gh-209 and gh-296)
- Prevent creation of a table with no columns.
- Fixed a memory leak that occured when iterating over
CArray/EArray objects.
- Make NaN types sort to the end. Closes gh-282 and gh-313
- Fixed selection on float columns when NaNs are present.
- Fix computation of the buffer size for iterations on rows.
The buffers size was overestimated resulting in a MemoryError
in some cases. Closes gh-316. Thamks to bbudescu.
- Better check of file open mode. Closes gh-318.
- The Blosc filter now works correctly together with fletcher32. Closes gh-21.
- Close the file handle before trying to delete the corresponding file.
Fixes a test failure on Windows.
- Use integer division for computing indices (fixes some warning on Windows)
- Use external python3-blosc. The internal one builds a bad version
of zlib.

- initial python3 package based on 3.0.0
New features
------------
* Since this release PyTables provides full support to Python_ 3
(closes :issue`188`).
* The entire code base is now more compliant with coding style guidelines
describe in the PEP8_ (closes :issue:`103` and :issue:`224`).
See `API changes`_ for more details.
* Basic support for HDF5 drivers. Now it is possible to open/create an
HDF5 file using one of the SEC2, DIRECT, LOG, WINDOWS, STDIO or CORE
drivers. Users can also set the main driver parameters (closes
:issue:`166`).
Thanks to Michal Slonina.
* Basic support for in-memory image files. An HDF5 file can be set from or
copied into a memory buffer (thanks to Michal Slonina). This feature is
only available if PyTables is built against HDF5 1.8.9 or newer.
Closes :issue:`165` and :issue:`173`.
* New :meth:`File.get_filesize` method for retrieving the HDF5 file size.
* Implemented methods to get/set the user block size in a HDF5 file
(closes :issue:`123`)
* Improved support for PyInstaller_. Now it is easier to pack frozen
applications that use the PyTables package (closes: :issue:`177`).
Thanks to Stuart Mentzer and Christoph Gohlke.
* All read methods now have an optional *out* argument that allows to pass a
pre-allocated array to store data (closes :issue:`192`)
* Added support for the floating point data types with extended precision
(Float96, Float128, Complex192 and Complex256). This feature is only
available if numpy_ provides it as well.
Closes :issue:`51` and :issue:`214`. Many thanks to Andrea Bedini.
* New :program:`pt2to3` tool is provided to help users to port their
applications to the new API (see `API changes`_ section).
Improvements
------------
* Improved runtime checks on dynamic loading of libraries: meaningful error
messages are generated in case of failure.
Also, now PyTables no more alters the system PATH.
Closes :issue:`178` and :issue:`179` (thanks to Christoph Gohlke).
* Improved list of search paths for libraries as suggested by Nicholaus
Halecky (see :issue:`219`).
* Removed deprecated Cython_ include (.pxi) files. Contents of
:file:`convtypetables.pxi` have been moved in :file:`utilsextension.pyx`.
Closes :issue:`217`.
* The internal Blosc_ library has been upgraded to version 1.2.1.
* Pre-load the bzip2_ library on windows (closes :issue:`205`)
* The :meth:`File.get_node` method now accepts unicode paths
(closes :issue:`203`)
* Improved compatibility with Cython_ 0.19 (see :issue:`220` and
:issue:`221`)
* Improved compatibility with numexpr_ 2.1 (see also :issue:`199` and
:issue:`241`)
* Improved compatibility with development versions of numpy_
(see :issue:`193`)
* Packaging: since this release the standard tar-ball package no more includes
the PDF version of the "PyTables User Guide", so it is a little bit smaller
now. The complete and pre-build version of the documentation both in HTML
and PDF format is available on the file `download area`_ on SourceForge.net.
Closes: :issue:`172`.
* Now PyTables also uses `Travis-CI`_ as continuous integration service.
All branches and all pull requests are automatically tested with different
Python_ versions. Closes :issue:`212`.
Other changes
-------------
* PyTables now requires Python 2.6 or newer.
