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 Open Babel and WildFly — release velocity, themes, recent moves, and the top alternatives to consider.
Six years quiet, then a feature release and a fuzzing-driven security cleanup.
Open Babel is a chemical file format conversion and cheminformatics toolkit. After 3.1.0 in 2020 the project went effectively dormant, then returned in May 2026 with 3.2.0 — a release combining real 3D geometry work with the results of a sustained fuzzing campaign run through OSS-Fuzz, with reports from Cisco TALOS, Trail of Bits, and ADA Logics. The 3.2.1 follow-up continues that: a CVE in the MMD parser, sscanf validation across several formats, and a stack overflow in the Gaussian and cube readers.
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 has re-engaged around two things at once — improving initial 3D structure generation, and hardening the format parsers that make Open Babel useful in the first place. Because it reads dozens of chemical file formats, often from untrusted sources, the parser surface is the attack surface, and the release notes now devote as much space to crash fixes as to chemistry. The project says more bug-fix releases are expected through 2026.
Expect continued fuzz-driven parser fixes on the 3.2.x line, since the crash reports arrive from external infrastructure rather than a roadmap.

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.
