Liquidsoap vs Vitest: at a glance
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 Vitest?
Vitest 5 is in bug-fix mode: the second RC is almost entirely hardening
rc.2 carries one feature — a custom title for the GitHub Actions summary — and otherwise fixes the failure modes the RC period surfaced. The browser mode gets most of it: failing instead of hanging when the browser stops responding, exiting cleanly on disconnect during cancellation, and triggering Chromium GC when disk runs low. Snapshot evaluation moved server-side to work under a no-unsafe-eval CSP, and the UI now requires auth for coverage reports and every subtree request.

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.
Vitest
5.0DEVOPS
Vitest 5 is in bug-fix mode: the second RC is almost entirely hardening
◆ Current state
rc.2 carries one feature — a custom title for the GitHub Actions summary — and otherwise fixes the failure modes the RC period surfaced. The browser mode gets most of it: failing instead of hanging when the browser stops responding, exiting cleanly on disconnect during cancellation, and triggering Chromium GC when disk runs low. Snapshot evaluation moved server-side to work under a no-unsafe-eval CSP, and the UI now requires auth for coverage reports and every subtree request.
◆ Where it's heading
The v5 line has spent four betas and two candidates reshaping config resolution, projects, mocking defaults, and the benchmark API; this candidate adds nothing to that surface and only stabilizes it. The concentration of browser-mode and pool fixes says that is where the remaining risk sits, and where real-world RC adoption is finding edges.
◆ Prediction
On this trajectory the next tag is either a final 5.0.0 or one more candidate, with browser mode the deciding factor rather than any remaining API work.
