+"pythoncomplete.vim - Omni Completion for python
+" Maintainer: <vacancy>
+" Previous Maintainer: Aaron Griffin <aaronmgriffin@gmail.com>
+" Version: 0.9
+" Last Updated: 2020 Oct 9
+"
+" Changes
+" TODO:
+" 'info' item output can use some formatting work
+" Add an "unsafe eval" mode, to allow for return type evaluation
+" Complete basic syntax along with import statements
+"   i.e. "import url<c-x,c-o>"
+" Continue parsing on invalid line??
+"
+" v 0.9
+"   * Fixed docstring parsing for classes and functions
+"   * Fixed parsing of *args and **kwargs type arguments
+"   * Better function param parsing to handle things like tuples and
+"     lambda defaults args
+"
+" v 0.8
+"   * Fixed an issue where the FIRST assignment was always used instead of
+"   using a subsequent assignment for a variable
+"   * Fixed a scoping issue when working inside a parameterless function
+"
+"
+" v 0.7
+"   * Fixed function list sorting (_ and __ at the bottom)
+"   * Removed newline removal from docs.  It appears vim handles these better in
+"   recent patches
+"
+" v 0.6:
+"   * Fixed argument completion
+"   * Removed the 'kind' completions, as they are better indicated
+"   with real syntax
+"   * Added tuple assignment parsing (whoops, that was forgotten)
+"   * Fixed import handling when flattening scope
+"
+" v 0.5:
+" Yeah, I skipped a version number - 0.4 was never public.
+"  It was a bugfix version on top of 0.3.  This is a complete
+"  rewrite.
