If you want to install\n``propcache`` on another operating system where wheels are not provided,\nthe the tarball will be used to compile the library from\nthe source code. It requires a C compiler and and Python headers installed.\n\nTo skip the compilation you must explicitly opt-in by using a PEP 517\nconfiguration setting ``pure-python``, or setting the ``PROPCACHE_NO_EXTENSIONS``\nenvironment variable to a non-empty value, e.g.:\n\n.. code-block:: console\n\n $ pip install propcache --config-settings=pure-python=false\n\nPlease note that the pure-Python (uncompiled) version is much slower. However,\nPyPy always uses a pure-Python implementation, and, as such, it is unaffected\nby this variable.\n\n\nAPI documentation\n------------------\n\nThe documentation is located at https://propcache.readthedocs.io.\n\nSource code\n-----------\n\nThe project is hosted on GitHub_\n\nPlease file an issue on the `bug tracker\n`_ if you have found a bug\nor have some suggestion in order to improve the library.\n\nDiscussion list\n---------------\n\n*aio-libs* google group: https://groups.google.com/forum/#!forum/aio-libs\n\nFeel free to post your questions and ideas here.\n\n\nAuthors and License\n-------------------\n\nThe ``propcache`` package is derived from ``yarl`` which is written by Andrew Svetlov.\n\nIt's *Apache 2* licensed and freely available.\n\n\n.. _GitHub: https://github.com/aio-libs/propcache\n\n=========\nChangelog\n=========\n\n..\n You should *NOT* be adding new change log entries to this file, this\n file is managed by towncrier.

annotations, fixing some type errors under correct usage\n and improving typing robustness generally -- by `@Dreamsorcerer `__.\n\n *Related issues and pull requests on GitHub:*\n `#103 `__.\n\n\n----\n\n\n0.3.0\n=====\n\n*(2025-02-20)*\n\n\nFeatures\n--------\n\n- Implemented support for the free-threaded build of CPython 3.13 -- by `@lysnikolaou `__.\n\n *Related issues and pull

-- by `@lysnikolaou `__.\n\n *Related issues and pull requests on GitHub:*\n `#84 `__.\n\n\nContributor-facing changes\n--------------------------\n\n- GitHub Actions CI/CD is now configured to manage caching pip-ecosystem\n dependencies using `re-actors/cache-python-deps`_ -- an action by\n `@webknjaz `__ that takes into account ABI stability and the exact\n version of Python runtime.\n\n .. _`re-actors/cache-python-deps`:\n https://github.com/marketplace/actions/cache-python-deps\n\n *Related issues and pull requests on GitHub:*\n `#93
