[winswitch] [ANNOUNCE] Xpra LTS 5.1.5

[Antoine Martin]

Hi,

This is another massive release, from the LTS branch this time.
This catches up with all the bug fixes that were already included in the 
stable branch.
There is nothing scary about these issues, and so there is no urgency to 
update if you were not affected.
That said, updating is always recommended and the MS Windows builds do 
include many updates to the underlying libraries, including some 
vulnerabilities, see the SBOM for details.

For more details, please see:

Cheers,
Antoine
