GStreamer 1.27.1 unstable development snapshot release

[Tim-Philipp Müller]

The GStreamer team is pleased to announce the first 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.
