   ### 54.0.0
   ```
   -------


Breaking Changes
^^^^^^^^^^^^^^^^
* 2582: Simplified build-from-source story by providing bootstrapping metadata in a separate egg-info directory. Build requirements no longer include setuptools itself. Sdist once again includes the pyproject.toml. Project can no longer be installed from source on pip 19.x, but install from source is still supported on pip &lt; 19 and pip &gt;= 20 and install from wheel is still supported with pip &gt;= 9.

Changes
^^^^^^^
* 1932: Handled :code:`AttributeError` by raising :code:`DistutilsSetupError` in :code:`dist.check_specifier()` when specifier is not a string -- by :user:`melissa-kun-li`
* 2570: Correctly parse cmdclass in setup.cfg.

Documentation changes
^^^^^^^^^^^^^^^^^^^^^
* 2553: Added userguide example for markers in extras_require -- by :user:`pwoolvett`
   ```
   
  
  
   ### 53.1.0
   ```
   -------


Changes
^^^^^^^
* 1937: Preserved case-sensitivity of keys in setup.cfg so that entry point names are case-sensitive. Changed sensitivity of configparser. NOTE: Any projects relying on case-insensitivity will need to adapt to accept the original case as published. -- by :user:`melissa-kun-li`
* 2573: Fixed error in uploading a Sphinx doc with the :code:`upload_docs` command. An html builder will be used.
  Note: :code:`upload_docs` is deprecated for PyPi, but is supported for other sites -- by :user:`melissa-kun-li`
