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 withr?

withr rebuilt defer() on base R's own on.exit(), and got much faster for it

withr provides the with_ and local_ functions that temporarily change global state and restore it on exit - the cleanup primitive under most of the tidyverse test suites. Version 3.0.0 reimplemented defer() as a thin wrapper over base::on.exit(), which the maintainers made possible by contributing the required arguments to R 3.5 itself. Everything since has been small correctness work.

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.

withr rebuilt defer() on base R's own on.exit(), and got much faster for it

◆ Current state

withr provides the with_ and local_ functions that temporarily change global state and restore it on exit - the cleanup primitive under most of the tidyverse test suites. Version 3.0.0 reimplemented defer() as a thin wrapper over base::on.exit(), which the maintainers made possible by contributing the required arguments to R 3.5 itself. Everything since has been small correctness work.

◆ Where it's heading

The arc here is a package pushing its own machinery down into base R and then living off the result. Once defer() became on.exit(), the remaining work is about where cleanup is allowed to happen - knitr documents, source() calls, the global environment, session end - and about restoring state correctly when an expression exits early. Releases are now infrequent and CRAN-driven.

◆ Prediction

Expect continued low-volume releases fixing edge cases in where deferred handlers run; with the core delegated to base R, there is little left that would prompt a larger change.
