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 PyTables?

PyTables opened a path around HDF5's filter pipeline, then chased Python's runtime.

PyTables is at 3.11.1, a one-line blosc2 loading fix. The structural change in the window is 3.10.0's direct chunking API, which lets callers read and write raw chunk data without going through the HDF5 filter pipeline, funded by a NumFOCUS grant. Since then the work has been runtime currency: NumPy 2, Python 3.13 and 3.14, free-threading compatibility and abi3 wheels.

Liquidsoap vs PyTables: 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.

0.0

PyTables opened a path around HDF5's filter pipeline, then chased Python's runtime.

◆ Current state

PyTables is at 3.11.1, a one-line blosc2 loading fix. The structural change in the window is 3.10.0's direct chunking API, which lets callers read and write raw chunk data without going through the HDF5 filter pipeline, funded by a NumFOCUS grant. Since then the work has been runtime currency: NumPy 2, Python 3.13 and 3.14, free-threading compatibility and abi3 wheels.

◆ Where it's heading

Two threads, both about overhead. The direct chunking API removes the filter pipeline from the hot path for callers who already know their compression; free-threading compatibility and threadsafe HDF5 wheels remove locking from concurrent reads. PyTables is positioning as the low-overhead route to HDF5 rather than competing on features with the format itself.

◆ Prediction

With the free-threading directive set and abi3 wheels shipping, the next release most likely consolidates that threading story — the notes already point readers to a separate threading cookbook — rather than extending the chunking API.
