Description

Python 3.8 has recently hit End-Of-Life (EOL) October 7, 2024. While there's been no great need to break compatibility, upstream dependencies will dropping support and will be harder to keep in-line. By having to constrain our dependencies to versions which still support 3.8, we're making it difficult to install PSR in an environment alongside other packages when do not support 3.8 and have pinned to versions higher than we can accommodate, and this problem obviously only worsens with time.

As a result of this, the intention is to release a breaking change on July 7, 2025, after which new versions of Python Semantic Release will no longer support Python 3.8.

    I ran into this while working on #1151 -- if you have a tool that implements strict dependency checks (like uv), the dependencies fail to resolve because one the dependencies (sphinx_autobuild) requires Python>=3.9:

      × No solution found when resolving dependencies for split (python_full_version == '3.8.*'):
  ╰─▶ Because the requested Python version (>=3.8) does not satisfy Python>=3.9 and sphinx-autobuild==2024.2.4 depends on Python>=3.9, we can conclude that
      sphinx-autobuild==2024.2.4 cannot be used.
      And because python-semantic-release[docs] depends on sphinx-autobuild==2024.2.4 and your project requires python-semantic-release[docs], we can
      conclude that your project's requirements are unsatisfiable.

      hint: The `requires-python` value (>=3.8) includes Python versions that are not supported by your dependencies (e.g., sphinx-autobuild==2024.2.4 only
      supports >=3.9). Consider using a more restrictive `requires-python` value (like >=3.9).

    Thanks for the note. Its not worth fixing since docs are not part of the actual wheel install and we don't use uv for development installs
