[winswitch] [ANNOUNCE] Xpra 2.5.3: many fixes, none critical

[Antoine Martin]

Hi,

Just like the previous update, this is a collection of fixes that had
accumulated, updating is recommended but none of the bugs are critical.

The main areas with fixes this time around are: HTML5 client, socket
layer (ssl, websockets, delays, mdns, warnings, etc), clipboard, shadow
servers, python3 compatibility fixes, a smattering of X11 issues, and
some more cosmetic or packaging issues.

The "ping latency" bug could explain some of the latency spiraling out
of control that had been reported in the past, but the 2.5.x already
included enough counter measures to mitigate the symptoms.

Hopefully, this should be the last release from the 2.5.x branch before
the 3.0 LTS release.
