pallets/markupsafe 3.0.0

on GitHub

This is the MarkupSafe 3.0.0 feature release. A feature release may include new features, remove previously deprecated code, add new deprecations, or introduce potentially breaking changes. The 3.0.x branch is now the supported fix branch, the 2.1.x branch will become a tag marking the end of support for that branch. We encourage everyone to upgrade, and to use a tool such as pip-tools to pin all dependencies and control upgrades. Test with warnings treated as errors to be able to adapt to deprecation warnings early.

Milestone: https://github.com/pallets/markupsafe/milestone/10?closed=1

• Support Python 3.13 and its experimental free-threaded build. #461
• Drop support for Python 3.7 and 3.8.
• Use modern packaging metadata with pyproject.toml instead of setup.cfg. #348
• Change distutils imports to setuptools. #399
• Use deferred evaluation of annotations. #400
• Update signatures for Markup methods to match str signatures. Use positional-only arguments. #400
• Some str methods on Markup no longer escape their argument: strip, lstrip, rstrip, removeprefix, removesuffix, partition, and rpartition; replace only escapes its new argument. These methods are conceptually linked to search methods such as in, find, and index, which already do not escape their argument. #401
• The __version__ attribute is deprecated. Use feature detection, or importlib.metadata.version("markupsafe"), instead. #402
• Speed up escaping plain strings by 40%. #434
• Simplify speedups implementation. #437
