From tomorrow, the release repository will now track the 0.22-fixes branch.

If you do not want to upgrade to 0.21 ; make sure you lock MythTV 0.21.

Make sure you read this entry before upgrading.

As well as the 0.22 transition guide:

The 0.22 packages available here will contain two extra backports.

http://svn.mythtv.org/trac/ticket/7307

Those are available in trunk already, but weren’t ready on time for 0.22. they will be in 0.23

Make sure you visit the Setup->General->Audio configuration page and make some adjustments to suit your set up. In particular, people with a digital surround system would need to change from Stereo to 5.1
