What is Liquidsoap?

Liquidsoap 2.5.0 reaches its first release candidate while 2.4 keeps getting patches.

Liquidsoap's 2.5.0 work, accumulated in a rolling release since August, reached a first release candidate on October 9, declared feature-complete and meant for staging rather than production. It brings subtitles as a content type, an Icecast-compatible server and a rewritten source composition model where switching fades by default. The 2.4 line continues in parallel: 2.4.6 on October 18 fixed fades, Icecast reconnection with chunked output and crossfade metadata.

What is Sonic?

Sonic yanks two releases in a day, then ships faster ingest and new count commands.

Sonic is a lightweight Rust search index that gained BM25 ranking in 1.8. On September 21 it released 1.9.0 with large PUSH performance gains and 1.9.1, then yanked both over two serious bugs and shipped 1.10.0 the same day with new COUNTC, COUNTB and COUNTO commands replacing COUNT. 1.10.1 fixed a CJK tokenizer panic on Chinese text and object counting, and 1.10.2 repaired backups.

Liquidsoap vs Sonic: editorial side-by-side

L5.0

Liquidsoap 2.5.0 reaches its first release candidate while 2.4 keeps getting patches.

◆ Current state

Liquidsoap's 2.5.0 work, accumulated in a rolling release since August, reached a first release candidate on October 9, declared feature-complete and meant for staging rather than production. It brings subtitles as a content type, an Icecast-compatible server and a rewritten source composition model where switching fades by default. The 2.4 line continues in parallel: 2.4.6 on October 18 fixed fades, Icecast reconnection with chunked output and crossfade metadata.

◆ Where it's heading

The project is in the run-up to a breaking release: 2.5 changes how switch, fallback, rotate and random take their arguments, so scripts will need edits. Keeping 2.4 patched in parallel gives users time to test before moving.

◆ Prediction

Further 2.5.0 release candidates and then a 2.5.0 final are the next likely entries, with another 2.4.x patch possible alongside.

DEVOPS
2.5

Sonic yanks two releases in a day, then ships faster ingest and new count commands.

◆ Current state

Sonic is a lightweight Rust search index that gained BM25 ranking in 1.8. On September 21 it released 1.9.0 with large PUSH performance gains and 1.9.1, then yanked both over two serious bugs and shipped 1.10.0 the same day with new COUNTC, COUNTB and COUNTO commands replacing COUNT. 1.10.1 fixed a CJK tokenizer panic on Chinese text and object counting, and 1.10.2 repaired backups.

◆ Where it's heading

The 1.x line is moving fast on ingest performance and correctness for high-scale and non-English users, at the cost of some unstable releases. Experimental APIs are being tested in production before they reach official builds.

◆ Prediction

Expect the experimental high-scale PUSH features to graduate out of the feature flag in a later 1.x; when is unclear.
