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 WildFly — 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.
WildFly's quarterly train is really a stability ladder, and OIDC keeps climbing it
WildFly is four majors into a metronomic release train — 38 through 41 in about eight months — where each cycle pairs a Beta with a Final roughly two weeks later that restates the same feature list. The substantive work splits cleanly in two: Jakarta EE 11 and MicroProfile spec implementations that land first in WildFly Preview, and an explicit stability ladder (preview to community to default) that individual features climb one release at a time. OIDC is the feature getting the most of that attention, with scope attributes, request/request_uri parameters, and logout each promoted across the last three cycles.

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.

OIDC is the feature getting the most of that attention, with scope attributes, request/request_uri parameters, and logout each promoted across the last three cycles.
The direction is consolidation rather than expansion: features already written are being graduated to supported status instead of new subsystems appearing. In parallel the runtime baseline is moving underneath users — 40.0.1 shipped container images for JDK 25 on UBI 10 and flagged it as the last release carrying JDK 17 images. Expect the EE 11 work now sitting in Preview to graduate into standard WildFly on the same ladder OIDC has been walking.
WildFly 42 should ship container images on JDK 21 and JDK 25 only, with the remaining Preview-stability EE 11 integrations promoted toward default.
