cpp11 vs Liquidsoap: at a glance
What is cpp11?
cpp11 has spent two years rebuilding itself on R's supported API surface
cpp11 is the header-only C++ interface for R packages, and nearly every release in this window is governed by one force: R core's tightening of what counts as non-API. 0.5.0 removed the growable-vector internals that made push_back() cheap, 0.5.3 and 0.5.4 removed further non-API usage, and the small releases in between are crash and compiler-warning fixes.
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.

cpp11 has spent two years rebuilding itself on R's supported API surface
◆ Current state
cpp11 is the header-only C++ interface for R packages, and nearly every release in this window is governed by one force: R core's tightening of what counts as non-API. 0.5.0 removed the growable-vector internals that made push_back() cheap, 0.5.3 and 0.5.4 removed further non-API usage, and the small releases in between are crash and compiler-warning fixes.
◆ Where it's heading
The package is trading a little performance for the right to keep passing CRAN checks indefinitely, and saying so plainly in the release notes. With R >= 4.0 now required, whole compatibility branches have been deleted rather than maintained. The remaining work is narrow: finish the non-API migration, then get back to interface features like cpp_source() handling multiple files.
◆ Prediction
Expect the last non-API dependencies to be cleared and the deprecated compatibility defines to be removed outright; the entries suggest maintenance discipline rather than new C++ surface.

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.
