[winswitch] [ANNOUNCE] Xpra 6.4.4

[Antoine Martin]

Hi,

This release is huge and contains just under 100 fixes!
The original plan was to release 6.5 sooner, but since this has not 
happened yet, it makes sense to have one last release from the v6.4.x 
branch to tidy up all the loose ends.
There are no scary issues, and there is no urgency to update if you are 
not affected - that said, with close to 100 bugs, chances are that at 
least one bug does affect most users.

For more details, please see:

The MacOS builds are once again causing new issues, and may appear at a 
later date - or only with the 6.5 release.

Cheers,
Antoine
