Release notes for GStreamer 1.4.0

The GStreamer team is pleased to announce the first release of the stable 1.4 release series. The 1.4 release series is adding new features on top of the 1.0 and 1.2 series and is part of the API and ABI-stable 1.x release series of the GStreamer multimedia framework.

Binaries for Android, iOS, Mac OS X and Windows are provided together with this release.

The stable 1.4 release series is API and ABI compatible with 1.0.x, 1.2.x and any other 1.x release series in the future. Compared to 1.2.x it contains some new features and more intrusive changes that were considered too risky as a bugfix.

The versioning scheme that is used in general is that 1.x.y is API and ABI backwards compatible with previous 1.x.y releases. If x is an even number it is a stable release series and all releases in this series will only contain important bugfixes, e.g. the 1.0 series with 1.0.7. If x is odd it is a development release series that will lead to the next stable release series 1.x+1 and contains new features and bigger changes. During the development release series, new API can still change.

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