2.0.0

• Supported Python versions:
  • Dropped support for old Python versions including 3.9 due to EOL of these versions.
  • Add support for Python 3.10 to 3.14.
• Quality:
  • Ensure with an automatic workflow that coverage is 97% or higher.
  • Enabled stricter mypy type checking (disallow_untyped_defs and disallow_incomplete_defs).
  • Converted all docstrings to Google format.
• Security:
  • Publish to PyPI with a Trusted Publisher / OIDC.
• New:
  • Use package-specific logger (logging.getLogger('compatibility')) instead of root logger. This allows users to selectively control compatibility's log verbosity independently from their application's logging.
  • Use custom exceptions (ParameterContradiction and BadDate).
  • Improved messages
  • Translations:
    • Translations now use the gettext standard module instead of a custom solution. That makes it easier to add new languages.
    • All messages are now available in English and German.
    • The language_messages parameter now works correctly - each Check instance uses the language specified in its parameter rather than the environment variable.
• Bugfixes:
  • Fixed inverted comparison logic in max_tested_version check. Previously warned when running an older Python version than tested; now correctly warns when running a newer version than tested.
  • Map Darwin to MacOS for proper macOS detection (platform.system() returns 'Darwin' on macOS).
  • Fixed version regex to properly capture release levels (alpha, beta, candidate, final). Changed from lazy ?? to greedy ? quantifier, which now correctly parses version strings like "3.10.alpha".
  • Replaced logger.exception() with logger.error() before raising intentional exceptions to avoid noisy duplicate tracebacks in logs.
