Hi,

There's a large number of bug fixes in this release, and quite a few of
these bugs are critical. In particular:
* the HTML5 XSS is trivial to exploit
* the focus issues can be a real nuisance (mostly affects GTK3)
* then there are bugs that could cause the server to crash - never a
good thing, or render it unbearably slow
* the MS Windows GTK3 client could get thoroughly confused by some
window constraints (ie: Firefox maximized)

Then there's the usual set of keyboard, clipboard, system tray, NVENC,
platform and application quirks, etc

Also noteworthy is the update to the application hints list:
http://xpra.org/trac/changeset/25902/xpra
If your preferred applications are not in that list, it is a good idea
to submit them: this helps the xpra server make the correct decisions.

Updating is strongly recommended.
