differing only by inst returning structured types.
+ Fix incorrect type checking of polymorphic functions with
type-inst IDs inside structured types.
+ Fix evaluation error when boolean variables are fixed during
flattening.

.ozn files.
+ Fix definition of array_intersect so that it can be used in
non-positive contexts.
+ Fix standards definitions of increasing variants to correct
be ignored when the argument array is empty.
+ Fix a problem where exceptions thrown for undefined
expressions were not caught during the aggregation of linear
expressions, breaking relational semantics.

array_intersect.

FlatZinc for consistency.

+ Fix incorrect message for par array out of bounds indicating
that array is empty
+ Fix incorrect propagation of Boolean variables potentially
causing output not accepted by Gecode and Chuffed.
+ Fix a problem where the usage of lb on a Boolean expression
would return -infinity..
+ Fix omission of error location when there is no stack trace
available.
+ Fix type specialisation to always make par versions of
functions available for output.
+ Fix internal error when checking return value of functions
involving arrays of optional values.
+ Fix incorrect false values for has_output_item when running

+ Add ability to set the ports used for the visualisation
server.
+ Add option for printing the visualisation server URL for
debugging purposes.

- update to 2.8.0:
* Changes in interfaces to solvers:
+ OR-Tools is now bundled with the MiniZinc IDE on all
platforms.

linked, and now supports outputting intermediate solutions
for optimisation problems.
+ Add support for producing a JSON-based version of FlatZinc as
the output format of the MiniZinc compiler.
+ Replace supportsMzn, supportsFzn and supportsNL solver
configuration flags with new option inputType. The old flags

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
