What is Open Babel?

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.

What is RESTEasy?

Jakarta REST implementation in pure maintenance across two parallel branches.

RESTEasy is the Jakarta RESTful Web Services implementation used by WildFly, and it ships every release twice — once on the 7.0.x line and once on 6.2.x, usually within an hour of each other. The overwhelming majority of each release note is Dependabot version bumps. Real fixes appear one or two per release and land on both branches: resource methods inherited from package-private classes not being registered, EJB interface methods not scanned for endpoint annotations, SSE response headers not committed when closing without sending.

Open Babel vs RESTEasy: editorial side-by-side

O0.0

Six years quiet, then a feature release and a fuzzing-driven security cleanup.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

Expect continued fuzz-driven parser fixes on the 3.2.x line, since the crash reports arrive from external infrastructure rather than a roadmap.

5.0

Jakarta REST implementation in pure maintenance across two parallel branches.

◆ Current state

RESTEasy is the Jakarta RESTful Web Services implementation used by WildFly, and it ships every release twice — once on the 7.0.x line and once on 6.2.x, usually within an hour of each other. The overwhelming majority of each release note is Dependabot version bumps. Real fixes appear one or two per release and land on both branches: resource methods inherited from package-private classes not being registered, EJB interface methods not scanned for endpoint annotations, SSE response headers not committed when closing without sending.

◆ Where it's heading

The project is tracking the Jakarta EE platform rather than pushing it — migrating to Jakarta Persistence 3.2, aligning @Inject handling with the CDI specification so resources no longer need a public no-arg constructor, and moving to JUnit 6 internally. There is no visible feature agenda beyond specification conformance and keeping the dependency tree current.

◆ Prediction

Expect the two-branch pattern to continue with the same fix backported to each; nothing in these entries indicates when 6.2.x support ends.
