# GStreamer 1.20 Release Notes
GStreamer 1.20 has not been released yet. It is scheduled for release in early February 2022.
1.19.x is the unstable development version that is being developed in the git main branch and which will eventually result in 1.20, and 1.19.90 is the first release candidate in that series (1.20rc1).
1.20 will be backwards-compatible to the stable 1.18, 1.16, 1.14, 1.12, 1.10, 1.8, 1.6, 1.4, 1.2 and 1.0 release series.
GStreamer 1.20.0 was released on 3 February 2022.

### Windows
- On Windows the high-resolution clock is enabled now in the `gst-launch-1.0` and `gst-play-1.0` command line tools, which provides better clock and timer performance on Windows, at the cost of higher power consumption. By default, without the high-resolution clock enabled, the timer precision on Windows is system-dependent and may be as bad as 15ms which is not good enough for many multimedia applications. Developers may want to do the same in their Windows applications if they think it's a good idea for their application use case, and depending on the Windows version they target. This is not done automatically by GStreamer because on older Windows versions (pre-Windows 10) this [affects a global Windows setting]( and also there's a power consumption vs. performance trade-off that may differ from application to application.

After the 1.20.0 release there will be several 1.20.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 1.20.x bug-fix releases will be made from the git 1.20 branch,
