MythTV 0.21 Released

kormoc writes "The new release has lots of new stuff, notably: autodiscovery (less manual configuration of new front-ends), storage groups (no need for LVM/etc), support for multiple recordings on one DVB/ATSC multiplex, a couple of new plugins, some new deinterlacing / video display options, and many, many other things. The release notes page in the wiki has the list of what's changed, but it's currently a couple thousand checkins out of date. Grab the release from the download section and please at least try to read the docs before asking questions. The binary packages should hopefully be updated to 0.21 soon."

My experience with the transition was that it was pretty much seamless.
