And now comes MythTV 0.27.3.
This is a minor update adding improvements in IPv6 supports, better PiP support for some hardware accelerated decoders and various corrections.
81 changes were made since 0.27.1.
We had a release-fart 0.27.2 that introduced some regressions with 3rd party clients (such as XBMC), due to the popularity of this client and despite the issue being theirs, it was decided to remove all fixes preventing their client to connect
