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 SimpleSAMLphp and WildFly — release velocity, themes, recent moves, and the top alternatives to consider.
Two maintenance branches, patched in lockstep, with release notes that say nothing but a checksum.
SimpleSAMLphp is running parallel 2.4 and 2.5 maintenance branches and patching both on the same day whenever a fix lands. The August releases are a coordinated security drop across the 2.5 line plus a 2.4 bugfix a day earlier. Release bodies carry no changelog text at all — just a download link, upgrade-notes pointer, and SHA256 checksums, so the feed tells operators when to patch but never what changed.
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.

This is pure maintenance cadence, not product development. The pattern across the last ten releases is consistent: security issues get simultaneous twin tags on both supported branches, everything else lands as branch-local bugfix points. The only release in the window that documented its own content was v2.4.6/v2.5.1 in May, which listed three GHSA advisories.
Expect the next tags to continue the twin-branch pattern — a paired 2.4.x and 2.5.x whenever an advisory lands, with content again deferred to the external changelog.

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.
