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 MapServer?

Five of MapServer's last six releases exist to fix security advisories.

Since 8.6.0 shipped in December 2025, every release on this feed has been a security release. 8.6.1 through 8.6.4 each carried one or two advisories, covering the SLD parser, the OpenLayers WMS template and PostGIS support. 8.6.5 carried six at once, spanning OGC API Features, WCS, the OpenLayers viewer, WMS GetLegendGraphic, and both MySQL and PostgreSQL JOIN handling. Every note repeats that 7.6 security support has ended and 8.4, 8.2 and 8.0 are unsupported.

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.

2.5

Five of MapServer's last six releases exist to fix security advisories.

◆ Current state

Since 8.6.0 shipped in December 2025, every release on this feed has been a security release. 8.6.1 through 8.6.4 each carried one or two advisories, covering the SLD parser, the OpenLayers WMS template and PostGIS support. 8.6.5 carried six at once, spanning OGC API Features, WCS, the OpenLayers viewer, WMS GetLegendGraphic, and both MySQL and PostgreSQL JOIN handling. Every note repeats that 7.6 security support has ended and 8.4, 8.2 and 8.0 are unsupported.

◆ Where it's heading

The advisory pattern is the story: the vulnerabilities cluster in the request-parsing and templating paths that turn user input into output, which is the oldest and most exposed part of a CGI-era mapping server. Concentrating all support on the 8.6 branch and repeatedly saying so is the project's way of forcing an upgrade it cannot otherwise compel. Feature content is not visible in this feed at all.

◆ Prediction

The cadence suggests further 8.6.x security releases at roughly monthly intervals rather than a feature release in the near term.
