Although we may not be known for using a witty naming scheme, and the version number only increments itself by a single "hundredth" every major release, we're extremely proud to announce the immediate release of what we loving refer to as - "0.25"! It's been 516 days (that's 1 year, 4 months, 30 days) since our last major release, so it goes without saying that a significant amount of work has made its way in to this current release with over 5200 commits making up 0.25.
MythTV version 0.25 includes several significant new features. A few key items to point out - new video acceleration capabilities such as VAAPI and DirectX Video Acceleration 2; expanded and improved audio capabilities including E-AC3, TrueHD, and DTS-HD support; Control your TV and other AV components via CEC (Consumer Electronics Control); enhanced and integrated metadata management capabilities for recordings and videos, and a fully functional API for third-party apps to build upon that can interact with both the frontend and backend - including a HTTP Live Streaming capabilities for delivering video content, in real-time, via the API.
Also noteworthy - MythMusic has been completely re-written and MythVideo is now directly integrated rather than being distributed as a separate plugin. Additionally, MythThemes is no longer maintained as a separate repository - all themes, including third party themes, can now be downloaded directly from the frontend theme chooser.
