[winswitch] [ANNOUNCE] Xpra 4.4.6: a few minor client-side issues

[Antoine Martin]

Hi,

This update to the v4.x branch fixes a few issues.
These are mostly platform specific and client side, in particular:
* an OpenGL sanity check regression introduced in 4.4.5, which caused 
the clients to run without OpenGL acceleration
* an annoying client-side focus issue has finally been solved
* missing system tray on Linux and Wayland
Everything else is all fairly minor, there is no urgency to update if 
you were not affected.

The detailed release notes can be found here:
