Deprecations:

Special Recognitions:
Potential Upgrade Incompatibility:
This update removes included contrib libraries that are dependencies for the cement command line tool to function (PyYAML, and Jinja2). The dependencies are now included via the cement[cli] extras package.
This is not an upgrade incompatibility in the core Cement code, and it would not affect any applications that are built on Cement. That said, it does have the potential to break any automation or other uses of the cement command line tool.

Deprecation:
Everything with deprecation notices in Cement < 3
Many thanks to for their contributions in modernizing the packaging system. Cement was started in 2009, and has some lingering technical debt that is now being addressed. Their contribution was a major help in moving off of setuptools and on to PDM and pyproject.toml, along with initial implementations of Ruff for a new generation of code compliance. I sincerely appreciate your help!
Many thanks to for their contributions toward adding type annotations in . This PR was too large to merge directly, but it is serving as a guide to finally begin work toward adding type annotations to Cement. This was a massive effort, and is very helpful to have this work available to guide the effort even if it will not be merged directly.
