Release notes for GStreamer 0.11.0 "It's a boy"

The GStreamer team is proud to announce the first release in the 0.11.x unstable series of the core of the GStreamer streaming media framework.

The 0.11.x series is an unstable series targeted at developers and will eventually lead up to the stable 1.0 series. It is not API or ABI compatible with the stable 0.10.x series. It is, however, parallel installable with the 0.10.x series.

The 0.11.x series has improved memory management and features various cleanups 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
