  * Bug fixes:
    + Fix incorrect FlatZinc definition in the gecode_presolver
      solver library.
    + Fix type specialisation for function with an polymorphic
      array argument and a non-array return type with the same
      type-inst identifier.
    + Fix crash during typechecking of overloaded functions
      differing only by inst returning structured types.
    + Fix incorrect type checking of polymorphic functions with
      type-inst IDs inside structured types.

      flattening.
    + Fix incorrect call names output when generating .ozn files.
    + Fix incorrect output of record access as tuple access in
      .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.
    + Fix crash when calculating computed domain of a declaration.
    + Fix x-y line/scatter visualisations.
  * Changes:
    + Support var set``s of enums for ``array_union and
      array_intersect.
    + Support var enums for the .. range operator.
    + Always perform substitution of fixed values before outputting
      FlatZinc for consistency.
  * Changes in the IDE:
    + Make process handling more robust to failures.
- update to 2.8.1:
  * Bug fixes:
    + 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
      with --model-interface-only
    + Fix translation of search annotations with multi-dimensional
      arrays as arguments.
    + Fix bug in output generation for some visualisation functions.
    + Fix problem where tuple or record assignments would sometimes
      trigger segmentation faults.
    + Fix context when binding the result of flattening a
      concatenation operation, resolving a possible segmentation
      fault.
    + Fix incorrect possible evaluation error for in operator
      involving an array RHS.
  * Changes:
    + Add --solution-checker option to allow specifying the
      solution checker (allowing use from a parameter configuration
      .mpc file).
    + Produce tighter bounds in compute_mod_bounds for the
      mod operator.
  * Changes in the IDE:
    + Fix command used to run findMUS and Globalizer.
    + Add ability to set the ports used for the visualisation
      server.
    + Add option for printing the visualisation server URL for
      debugging purposes.
    + Add more information to subprocess error messages.
- update to 2.8.0:
  * Changes in interfaces to solvers:
    + OR-Tools is now bundled with the MiniZinc IDE on all
      platforms.
    + HiGHS is now loaded as a dynamic plugin instead of statically
      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
      are still supported for backwards compatibility.
    + Add experimental support for restart based meta-search
      specification for the Gecode and Chuffed solvers, as first
      explored in Solver-Independent Large Neighbourhood Search and
      A Modern Architecture for Constraint Modelling Languages.
    + Automatically detect current versions of CPLEX.
  * Changes in the MiniZinc Library:

      add enumerated type typesafety between the values of the
      decision variables and the cover parameters.
    + Add optional versions of count_* global constraints.
    + (strictly_)decreasing will now always be rewritten into
      (strictly_)increasing and has support for option types.
    + Allow libraries to define how to iterate over var set of int
      using the function set2iter, useful for different set
      representations.
    + Stabilise the IDE visualisation library, allowing all
      visualisation functions to be used from output statements,
      and removing the need for manual calls to showJSON in custom
      visualisations. This is a breaking change for users of the
      previous experimental API.
    + Add mzn_half_reify_clause compiler option to allow solvers to
      disable the half reification of bool_clause constraints.
    + Update the reflection functions ub, lb, and dom to return
      enum values.
    + Use tuples to implement the decomposition of optional
      variables, avoiding possible CSE aliasing problems.
  * Changes in the compiler:
    + CSE has been adjusted to handle commutative functions when
      annotated using the promise_commutative annotation.
    + mzn_reverse_map_var is now only called on output variables
      that do not yet have reverse mappers after initial
      flattening, but are required by the output model.
    + Improve error messaging for invalid parameter configuration
      (.mpc) files.
    + Add a list of messages generated by solution checkers to the
      checker message when using --json-stream.
    + Support output of command line argument parsing errors in
      --json-stream mode.

      versions of functions involving tuples/records.
    + Ensure that when --solver is used, the given solver
      configuration file is always selected even when it collides
      with a solver in the search paths.
    + Fix error when running satisfaction problems using the Gecode
      presolver where an output variable is also an
      introduced variable.
    + Resolve a problem where unification in the optimization phase
      might remove variables part of the output.
    + Fix possible crash when printing the final solution using the
      built-in Chuffed interface.
    + Don’t print the final status line from solution checkers.
    + Fix typechecking of par type-inst identifiers when
      instantiated using structured types involving var types.
    + Implement fix and is_fixed for strucutred types.
    + Ensure reverse mappers are created when flattening
      tuple/record literals. This resolves certain errors during
      output processing in models using these types.
    + Fix problem where certain strings in exceptions might be
      garbage collected before they are output.
    + Fix problem where argument names of generated functions could
      conflict with model declared names.
    + Fix problem where the common type of complex records or
      tuples was not correctly determined in the array literals.
    + Fix a problem in the parser where a nullptr would be used
      before a syntax error was thrown.
    + Fix error management when reading preference files.
    + Fix segmentation fault caused by the creation of invalid
      domain constraints generated for functions with arrays of
      tuples or records parameters.
    + Fix crash when instantiating a type-inst identifier using
      only <>.
    + Fix evaluation of comprehensions containing opt string.
    + Fix crash when instantiating polymorphic functions using
      tuples/records with many var or opt fields.
    + Do not generate default DZN output when there are only
      sectioned output items present.
    + Fix the edge indexing of the edges for the final node in the
      neural_net global constraint.
    + Add better error messaging when an index set mismatch is
      encountered in the standard library.
    + Fix evaluation error when indexing into an array using <>.
    + Fix incorrect unsatisfiability when equating optional
      variables with non-intersecting domains.
    + Fix array access using optional indices for multidimensional
      arrays.
    + Fix output of zero length arrays of optional variables.
    + Fix output processing performance degradation when printing
      arrays in DZN output mode.
    + Fix card function on set of floats and bools.
    + Make set literals containing strings or annotations a
      type error.
  * Changes in the IDE:
    + Fix unreadable cheat sheet font colour in dark mode.
    + Add option to output objective value and enable by default.
    + Show manually input parameters in output window.
    + Fix missing checker messages.

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
