Release notes for GStreamer 0.9.7 "My Dog Has No Nose"

The GStreamer team is petrified to announce a new release in the 0.9.x development series of the core of the GStreamer streaming media framework.

The 0.9.x series is a development series and not recommended for 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.

This release is a pre-release for the new 0.10 stable series. The major/minor has been bumped to 0.10 - update your pkg-config magic if you're developing applications..

The main focus of the 0.9 series is to make GStreamer threadsafe.

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
