[winswitch] [ANNOUNCE] Xpra 4.0.2 and 3.0.10 LTS: some important fixes

[Antoine Martin]

Hi,

These updates to the LTS and stable branches contains some important
fixes, in particular:
* encryption option not honoured with websockets
* workaround for server startup failures
* packaging fixes and workarounds (ie: pyxdg bugs)
* HTML5 client fixes: almost half of the fixes are in the HTML5 client,
and those fixes are exactly the same for both branches, so they are
separated out below

Updating is recommended.

Cheers,
Antoine
