Release notes for GStreamer 0.10.25 "Feel the burn"

The GStreamer team is proud to announce a new release in the 0.10.x stable series of the core of the GStreamer streaming media framework.

The 0.10.x series is a stable series targeted at end users. It is not API or ABI compatible with the stable 0.8.x series. It is, however, parallel installable with the 0.8.x series.

The 0.10.x series has been reworked for threadsafety. It also features various feature additions and enhancements.

This module, gstreamer, only contains core functionality. For actual media playback, you will need other modules.

contains a basic set of well-supported plug-ins
contains a set of well-supported plug-ins under our preferred license
contains a set of well-supported plug-ins, but might pose problems for distributors
contains a set of less supported plug-ins that haven't passed the rigorous quality testing we expect
