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 stbl?

stbl keeps tightening its own defaults, accepting breakage now to avoid silent wrongness later.

A small R utility for stabilising function arguments — coercing, validating and erroring predictably on user input. Four releases across roughly two years, with the pace picking up in 2026. Every substantive release so far has led with a Breaking changes section, and the changes share a direction: behaviour that used to pass silently now errors, and permissive defaults become strict.

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.

2.5

stbl keeps tightening its own defaults, accepting breakage now to avoid silent wrongness later.

◆ Current state

A small R utility for stabilising function arguments — coercing, validating and erroring predictably on user input. Four releases across roughly two years, with the pace picking up in 2026. Every substantive release so far has led with a Breaking changes section, and the changes share a direction: behaviour that used to pass silently now errors, and permissive defaults become strict.

◆ Where it's heading

The package is converging on a single principle — an argument checker that quietly accepts bad input is worse than none. 0.3.0 flipped the scalar functions to reject NULL and zero-length input by default; 0.4.0 made to_df() and to_lst() error on extra arguments in dots that were previously discarded. Alongside the tightening, the surface is expanding beyond coercion into condition signalling: pkg_abort() has been joined by pkg_inform() and pkg_warn() with a matching class hierarchy, plus testthat helpers that assert on those classes and snapshot the output. That positions stbl less as a coercion helper and more as the argument-and-condition layer for a package author's whole public API.

◆ Prediction

Expect the condition-signalling side to keep growing toward parity with the coercion side, and further default-tightening releases each fronted by a breaking-changes list.
