[winswitch] [ANNOUNCE] Xpra 6.3.5

[Antoine Martin]

Hi,

This release includes a fix for a serious security issue for multi-user 
systems - which should get a CVE assigned eventually.
This is a regression from the 6.3.x series and older branches are not 
affected.

Everything else looks fairly normal.
The `move-resize` fix solves window positioning and resizing issues with 
some applications, notably electron applications like vscode.

For more details, please see:

Cheers,
Antoine
