What is Liquidsoap?

Liquidsoap opens its 2.5 line with subtitles as a first-class content type and a streaming server of its own

The 2.5.x rolling release carries the accumulated 2.5.0 changelog, and it is the largest body of work Liquidsoap has staged in over a year. Subtitles become a dedicated content type alongside audio and video, with native SRT decoding, FFmpeg subtitle encode and decode, bitmap passthrough, callbacks, transformations and dynamic insertion. An Icecast-compatible server ships as icecast.server, with source authentication, mount points, relay and per-listener encoding. Underneath, the source composition model was rewritten: switch, fallback, rotate and random drop their parallel list parameters for per-source methods, and switching now fades by default.

What is QGroundControl?

v5.1 is in release-candidate stage, with the HUD pitch direction corrected.

QGroundControl is the cross-platform ground control station for MAVLink vehicles, used with PX4 and ArduPilot. It is currently between stable releases: v5.0 shipped in July 2025 and ran to 5.0.8, and v5.1 has been in release candidates since late July 2026. The most visible v5.1 change flagged so far is a correction to the HUD pitch indicator, which now moves down when the nose pitches down.

Liquidsoap vs QGroundControl: editorial side-by-side

L6.3

Liquidsoap opens its 2.5 line with subtitles as a first-class content type and a streaming server of its own

◆ Current state

The 2.5.x rolling release carries the accumulated 2.5.0 changelog, and it is the largest body of work Liquidsoap has staged in over a year. Subtitles become a dedicated content type alongside audio and video, with native SRT decoding, FFmpeg subtitle encode and decode, bitmap passthrough, callbacks, transformations and dynamic insertion. An Icecast-compatible server ships as icecast.server, with source authentication, mount points, relay and per-listener encoding. Underneath, the source composition model was rewritten: switch, fallback, rotate and random drop their parallel list parameters for per-source methods, and switching now fades by default.

◆ Where it's heading

Liquidsoap is expanding on two axes at once. It is broadening what a stream can carry - subtitles are a third content modality in a system that has understood two - and it is moving up the stack from a source that feeds Icecast into something that can be the Icecast. The language work points the same way: a source(_) type for unknown content, callback release semantics, and effect-scoped clocks are the kind of changes made when scripts are getting large enough that lifetime and typing errors cost real production time.

◆ Prediction

The 2.5.0 final should follow the rolling branch within a release cycle, and the migration guide already shipped for the composition parameter changes suggests the breaking surface is considered settled. Watch whether subtitle support reaches the harbor and Icecast server paths, which the current notes do not say.

Q5.0

v5.1 is in release-candidate stage, with the HUD pitch direction corrected.

◆ Current state

QGroundControl is the cross-platform ground control station for MAVLink vehicles, used with PX4 and ArduPilot. It is currently between stable releases: v5.0 shipped in July 2025 and ran to 5.0.8, and v5.1 has been in release candidates since late July 2026. The most visible v5.1 change flagged so far is a correction to the HUD pitch indicator, which now moves down when the nose pitches down.

◆ Where it's heading

The project releases in long RC chains before each stable - v5.0 took at least five candidates - and the notes for each candidate list only what changed since the previous one. RC2's own delta is documentation and CI: download links, AppImage requirements on Ubuntu 24.04, macOS signed universal build instructions. The substantive v5.1 work is summarised on an external What's New page rather than in the feed, so the tags themselves understate the release.

◆ Prediction

Given the RC1-to-RC2 gap and the docs-only nature of this delta, a v5.1 stable is the likely next tag rather than a third candidate - though the v5.0 chain ran to five, so more candidates would not be out of pattern.
