[winswitch] [ANNOUNCE] Xpra 2.3.3 : many fixes, none critical

[Antoine Martin]

Hi,

This release was delayed repeatedly and so the number of fixes is rather
large.
This delay was first caused by some hardware failures, then by the
switch to Python 3.7 for the MS Windows and MacOS Python 3 builds, which
required quite a few tweaks and fixes - many of which were in other
upstream projects.

Apart from those build-system related issues, the most important fixes
are in the HTML5 client's key handling, Python3 compatibility fixes, the
network layer (bandwidth-limit, congestion detection, etc) and SSL /
proxy server issues.

There is no urgency to update, but because of the large number of fixes,
updating sooner rather than later is recommended.
