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 Mapnik?

Mapnik is turning a local-file map renderer into a client of remote tile archives

Mapnik ships small, frequent point releases driven largely by one maintainer, with occasional outside contributions for build and platform fixes. The through-line since 4.1.0 is tiles.input: what started as vector-tile and PMTiles/MBTiles reading has grown network access over HTTPS, async metadata fetches, threading controls and direct z/x/y URL support. The 4.3.0 release turns attention back to the rendering core, fixing PostGIS connection-pool churn and multi-font Unicode text runs.

Liquidsoap vs Mapnik: editorial side-by-side

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.

Mapnik is turning a local-file map renderer into a client of remote tile archives

◆ Current state

Mapnik ships small, frequent point releases driven largely by one maintainer, with occasional outside contributions for build and platform fixes. The through-line since 4.1.0 is tiles.input: what started as vector-tile and PMTiles/MBTiles reading has grown network access over HTTPS, async metadata fetches, threading controls and direct z/x/y URL support. The 4.3.0 release turns attention back to the rendering core, fixing PostGIS connection-pool churn and multi-font Unicode text runs.

◆ Where it's heading

Two threads run in parallel. The datasource layer is being generalized — combined input plugins in 4.2.0, a more flexible plugin infrastructure in 4.2.1 — so that tile sources sit alongside PostGIS and GDAL as first-class inputs rather than bolt-ons. Meanwhile the C++ substrate is being modernized in place: boost::optional replaced by std::optional, sqlite I/O moved to unique_ptr, polylabel swapped for an in-house C++ port, and vector-tile compression started. The library is positioning to render directly from hosted tile archives instead of assuming everything is on local disk.

◆ Prediction

Vector-tile compression is explicitly marked work-in-progress, so expect 4.4.0 to finish it and to promote the experimental direct tile-URL support out of experimental status. The steady removal of Boost dependencies suggests further std:: replacements will keep arriving as incidental line items rather than as a headline migration.
