MiniZinc Python 0.3.1

Changed

• Store path of loaded solver configuration paths so that no configuration file
  has to be generated if no changes are made to the solver.

Fixed

• Ensure generated solver configurations exists during the full existence of
  the created asynchronous process.

MiniZinc Python 0.3.0

Added

• Add support for different MiniZinc compiler optimisation levels. All methods that
  compile an instance now have an additional optimisation_level argument.

Changed

• The DZN parser functionality has been moved into the dzn extra. If your
  application requires parsed dzn information, then you have to ensure your
  MiniZinc Python is installed with this extra enabled:
  pip install minizinc[dzn].
• Solver has been turned into a dataclass and has been updated with all
  attributes used in the compiler.

Fixed

• Resolve relative paths when directly loading a solver configuration. This
  ensures that when a temporary solver configuration is created, the paths are
  correct.

MiniZinc Python 0.2.3

Changed

• Add text to the empty MiniZincError that occurs when MiniZinc exits with a non-zero
  exit status

Fixed

• Close generated solver configuration before handing it to MiniZinc. This fixes the
  usage of generated solver configurations on Windows.
• The DZN parser now constructs correct range objects. The parser was off by one due to
  the exclusive upper bound in Python range objects.
• Rewrite MiniZinc fields that are keywords in Python. These names cannot be used
  directly as members of a dataclass. Python keywords used in MiniZinc are rewritten to
  "mzn_" + {keyword} and a warning is thrown.

MiniZinc Python 0.2.2

Added

• Add output property to CLIInstance to expose the output interface given by
  MiniZinc.

Changed

• Improved interaction with solution checker models. Solution checkers can
  now be added to an ```Instance/Model`` and an ``check`` method will be
  added to the generated solution objects.
• Change the Python packaging system back to setuptools due to the excessive
  required dependencies of Poetry.

Fixed

• Fix the MiniZinc output parsing of sets of an enumerated type.
• Fix the TypeError that occurred when a hard timeout occurred.
• Allow trailing commas for sets and arrays in DZN files.

MiniZinc Python 0.2.1

Added

• Add support for other command line flags for CLIInstance.flatten()
  through the use of **kwargs.
• Add initial Checker class to allow the usage of MiniZinc solution
  checkers.

Changed

• The string method for Result will now refer to the string method of its
  Solution attribute.

Fixed

• Ensure the event loop selection on Windows to always selects
  ProactorEventLoop. This ensures the usage on Windows when the python
  version <= 3.8.0.

MiniZinc Python 0.2.0

Added

• Support and testing for Python 3.8
• Logging of started processes and attributes of generated output items
• Export Pygments Lexer for MiniZinc

Changed

• Driver.check_version now raises an ConfigurationError exception
  when an incompatible function is detected; otherwise, the method not return a
  value.
• Output classes generated by CLIIinstance.analyse() no longer contain
  the _output_item str attribute when MiniZinc does not find a output item.
  (New in MiniZinc 2.3.3)
• Improved parsing of non-standard (numerical) statistical information
  provided by the solver.

Fixed

• CLIInstance.solutions(): The separator detection is now OS independent.
  The separator previously included a \n literal instead of \r\n on
  Windows.
• Solve an issue in CLIInstance.solution() where a solution with a size
  bigger than the buffer size would result in a LimitOverrunError exception.
• Correctly catch the asyncio.TimeoutError and kill the process when
  reaching a hard timeout. (i.e., the solver and minizinc do not stop in
  time)
• Check if file exists before opening file when an error occurs. (File might
  have been part of a compiled solver)
• Ensure the objective attribute is only added to the generated solution
  type once
• Remove '\r' characters from input when parsing statistics (Windows Specific).

MiniZinc Python 0.1.0

Initial release of MiniZinc Python. This release contains an initial functionality to use MiniZinc directly from Python using an interface to the minizinc command line application. The exact functionality available in this release is best described in the documentation.
