Undertow
Undertow 2.4.0 clears three CVEs and finally lands long-open HTTP/2 and timeout requests
A side-by-side editorial comparison of Liquidsoap and Meilisearch — release velocity, themes, recent moves, and the top alternatives to consider.
Liquidsoap spent the whole 2.4 line paying down the cost of its own rewrite
Liquidsoap is a scripting language and runtime for building audio and video streams. The 2.4 series has been almost entirely stabilization: five patch releases since November 2025, two of them shipped within days of each other because the preceding one broke source cleanup, and 2.4.4 arriving with an explicit recommendation to skip 2.4.3. The recurring subject matter is clocks, source lifecycle and resource leaks — sub-clock leaks, crossfade crashes when skip is called off-thread, encoder sharing, Strings.Mutable leaks.
Meilisearch shipped 1.52, then spent the same day reverting most of it.
Four releases landed on a single day. Both of 1.52.0's headline items — experimental SSE routes for tasks and batches, and an O(1) rewrite of document formatting — were reverted within a week, in 1.52.2 and 1.52.3. Meanwhile 1.53.0 went out the same day with sharding for foreign filters and new index size statistics. The additions that have actually held are in query capability: dynamic search rules gained filter-based activation conditions in 1.51.0.

The project said outright at 2.4.1 that the internal rewrite and feature work were done and that effort would shift to stability, and the release record since then matches that claim. What new surface has appeared is diagnostic or defensive rather than expansive: clock and source graph pretty-printing, telnet commands for queue and output control, and raw string literals that stop interpolation from executing untrusted input. Performance work has targeted the same subsystem as the bugs, with clock sync-source propagation moving from a full scan to push-based updates.
The 2.4.3 notes state that 2.4.x was meant to end there and that 2.5.x work has begun, yet two more patches have shipped since — so the branch is likely to keep absorbing clock and source fixes until 2.5 lands. The notes give no date for it.

Engine work is pushing along two axes — distributed operation, where foreign filters can now resolve documents across the network and the retrieval limit rose from 100 to 1000, and search-time programmability, where rules can activate on facet filters and pin results. The revert pattern is the other signal: push-based task streaming and the formatting optimization both went out before they were solid, which suggests the release train is running ahead of validation.
The reverted SSE streaming routes and the formatting optimization are the obvious candidates to return in a later release once their underlying issues are resolved — neither was withdrawn for lack of intent.
