- Add minimal checks
- Add patches:
* 0001-Disambiguate-UNKNOWN-EXCEPTION.patch
* 0002-Catch-std-exception-by-const-reference.patch
* 0003-Try-to-get-some-more-information-when-catching.patch
-------------------------------------------------------------------
Thu Nov 9 09:14:34 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 2.7.6:
* Change the library and solver configuration path of builtin
version of Chuffed to prevent file conflicts
* Use the verbose compilation flag to control the verbosity of
the MIP domains stage
* Introduces the ``arg_val`` and ``arg_val_weak`` globals that
return the index of the first occurrence of a value in a given
array.
* Introduces the ``var_perm_sym`` and ``var_sqr_sym`` symmetry
breaking globals.
* Enable parallel search for the built-in Gecode presolver.
* Use native Qt dark mode on Windows where supported.
* Improve behaviour of the custom solver parameter dialog.
* ``ASTString`` constructor that uses ``std::string`` is now
explicit to avoid unexpected or unnecessary GC allocation.
* Circular definitions through the use of annotations will now
be reported as type errors, rather incurring infinite recursion
* Optimize the compilation of identical calls in different
contexts by recursively changing the contexts of the (uncompiled)
dependent calls, instead of flattening multiple times.
* Change domains of set variables when encountering (par)
equalities, or negated ``in`` constraints at the root level.
* Calls to ``min`` and ``max`` with ``par set of int`` type
argument will now be undefined (becoming ``false`` in the
closest Boolean context). This makes them consistent with
the calls with an argument of type ``var set of int``.
* Note that previous behaviour would have returned ``infinity``
or ``-infinity`` respectively (:bugref:`661`).
* Only show MOOC error code when response is actually an error
* Add documentation for ``--input-is-flatzinc`` flag
* Add ``ceil``, ``floor`` and ``round`` functions for ``var
float``, and corresponding FlatZinc builtins ``float_ceil``,
``float_floor`` and ``float_round`` that can be overridden
by solvers in the new ``redefinitions-2.7.1.mzn`` library file
* Fix highlighting of multiline comments starting with ``/*/``
* Fix bundling of incompatible OpenSSL version in linux
packages.
* Support for tuple and record types as well as type-inst
synonyms has been added.
* Extended enumerated types can now be constructed from non-
contiguous sets.
* WebAssembly is now fully supported as a target platform.
* MiniZinc now includes a solver interface for the `HiGHS
linear optimisation suite. HiGHS is included by default in
the MiniZincIDE package, and available using ``--solver highs``.
* The SCIP interface has been updated and is now compatible
with version 7 and 8 only.
* A solver's globals library specified in a configuration file
will now always be passed to the compiler using the ``-G``
flag. This allows users to easily override this library from
command line when required.
* Automatically detect Gurobi 10.0 and potential future
versions.
* Avoid loading all solver plugin DLLs on startup, instead
loading when required.
* The non-FlatZinc interfaces now also accept the ``--free-
search`` flag in addition to the ``-f`` flag.
* Ensure user config directory is created when modifying
solver search paths (:idebugref:`167`).
* Add tooltips to the CP-Profiler status bar legend.
* Add support for mooc submissions which include file editing
history.
* bugfixes
