The GStreamer team is pleased to announce another development release in
the API/ABI-unstable 1.27 release series.
The API/ABI-unstable 1.27 release series is for testing and development purposes
in the lead-up to the stable 1.28 series which is scheduled for release in late
2025. Any newly-added API can still change until that point.
This development release is primarily for developers and early adopters, and
distros should probably not package it.
