Changelog does not contain unreleased changes from appdirs that were made before forking

[Jackenmen]

In particular changelog does not contain breaking changes that were made in appdirs's master branch before forking, for example the change to user_config_dir and site_config_dir:
ActiveState/appdirs#63

There might be more but this is the one change that I know of that can definitely be breaking for existing applications.

Update: it appears that appdirs 1.4.4 changelog contains it but version 1.4.4 did not make that change which you can see here:
https://github.com/ActiveState/appdirs/blob/1.4.4/appdirs.py#L195

A PR would be very welcome if you can for this.

Other (IMO) noteworthy changes that I've found while looking through commit log:

• added support for Python 3.8 and 3.9 (changelog only mentions 3.7)
• dropped pywin32 dependency
• added os.environ fallback for jython (not entirely sure whether appdirs 1.4.4 was affected as the logic for getting appdata seems to have changed since 1.4.4 as well and it might just be a bug that was only ever in master)

A PR would be very welcome if you can for this.

Well, I guess that now that I finished writing other stuff that could be added, I might as well PR, will do so in a moment 😄

Also since I'm already commenting...
CC: @gaborbernat as I know you released a new virtualenv version and I'm not entirely sure whether you were aware of the breaking change I mentioned in the issue description.
