What is Apache Kafka?

Kafka's release train pairs a feature-rich 4.3 with a steady run of critical bugfix point releases.

Apache Kafka is in active maintenance across multiple branches. The recent feed is dominated by bugfix point releases (4.3.1, 4.2.1, 4.1.2, 4.0.2, 3.9.2) bracketing the feature release 4.3.0, which landed 25 KIPs and over 600 commits. The project is shipping new capability on the minor line while back-porting critical fixes across supported versions.

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.

Apache Kafka vs RESTEasy: editorial side-by-side

Apache Kafka logo2.5

Kafka's release train pairs a feature-rich 4.3 with a steady run of critical bugfix point releases.

◆ Current state

Apache Kafka is in active maintenance across multiple branches. The recent feed is dominated by bugfix point releases (4.3.1, 4.2.1, 4.1.2, 4.0.2, 3.9.2) bracketing the feature release 4.3.0, which landed 25 KIPs and over 600 commits. The project is shipping new capability on the minor line while back-porting critical fixes across supported versions.

◆ Where it's heading

The cadence shows a maturing post-4.0 KRaft-era project: feature work concentrated in minor releases (4.2 made Share Groups production-ready, 4.3 builds further), with disciplined bugfix and security back-ports keeping older branches viable. Expect the queues and Share Groups line and KRaft consistency work to keep advancing.

◆ Prediction

Expect a 4.4 feature release continuing the Share Groups and KRaft trajectory, with bugfix point releases continuing across supported branches in between.

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.
