[winswitch] [ANNOUNCE] xpra-html5 v5.4

[Antoine Martin]

Hi,

This new release from the old v5.x branch of the html5 client is only 
meant to be used with servers stuck on the old 3.1.x LTS branch.
Just like the v10 release that precedes it, it fixes some potential 
vulnerabilities by updating the jquery and jquery-ui libraries.

For more details, please see:

Cheers,
Antoine
