## GStreamer Python Bindings

gst-python is an extension of the regular GStreamer Python bindings based on gobject-introspection information and PyGObject,
and provides “syntactic sugar” in form of overrides for various GStreamer APIs that makes them easier to use in Python and more
pythonic; as well as support for APIs that aren’t available through the regular gobject-introspection based bindings, such as
e.g. GStreamer’s fundamental GLib types such as Gst.Fraction, Gst.IntRange etc.

## GStreamer C# Bindings

-   to be filled in

-   GStreamer API added in recent GStreamer releases is now available

## GStreamer Rust Bindings and Rust Plugins

The GStreamer Rust bindings and plugins are released separately with a different release cadence that’s tied to the twice-a-year
GNOME release cycle.

The latest release of the bindings (0.23) has already been updated for the new GStreamer 1.26 APIs, and works with any GStreamer
version starting at 1.14.

gst-plugins-rs, the module containing GStreamer plugins written in Rust, has also seen lots of activity with many new elements
and plugins. The GStreamer 1.26 binaries track the 0.13 release series of gst-plugins-rs, and fixes from newer versions will be
backported as needed to the 0.13 brach for future 1.26.x bugfix releases.

Rust plugins can be used from any programming language. To applications they look just like a plugin written in C or C++.

### WebRTC

-   to be filled in

### Other new Rust elements

### Other improvements

For a full list of changes in the Rust plugins see the gst-plugins-rs ChangeLog between versions 0.12 (shipped with GStreamer
1.24) and 0.13 (shipped with GStreamer 1.26).

## Build and Dependencies

-   The GLib requirement has been bumped to >= 2.64

-   liborc >= 0.4.40 is strongly recommended

Stable 1.26 branch

After the 1.26.0 release there will be several 1.26.x bug-fix releases which will contain bug fixes which have been deemed
suitable for a stable branch, but no new features or intrusive changes will be added to a bug-fix release usually. The 1.26.x
bug-fix releases will be made from the git 1.26 branch, which will be a stable branch.

Schedule for 1.28

Our next major feature release will be 1.28, and 1.27 will be the unstable development version leading up to the stable 1.28
release. The development of 1.27/1.28 will happen in the git main branch of the GStreamer mono repository.

The schedule for 1.28 is yet to be decided.

1.28 will be backwards-compatible to the stable 1.26, 1.24, 1.22, 1.20, 1.18, 1.16, 1.14, 1.12, 1.10, 1.8, 1.6, 1.4, 1.2 and 1.0
release series.
