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
