What is Jenkins?

Jenkins is shrinking its own war file and rebuilding its UI, one weekly release at a time

The weekly train is dominated by two long efforts: an incremental redesign of the experimental Manage Jenkins UI, and a deliberate campaign to unbundle plugins from jenkins.war. 2.577 drops bouncycastle, the Command Agent Launcher, JAXB, the SSH server and more, following 2.574's removal of JUnit, Mailer and the matrix plugins. Interleaved security releases ship with no detail beyond a one-line note.

What is NATS?

NATS second release candidates add a config reload check and faster redelivery queues.

NATS keeps the 2.14 and 2.15 lines in step, and on November 6 both got a second release candidate. The RCs make filtered filestore scans skip non-matching messages, stop redelivery queues from copying whole backlogs on each dequeue, and fix AckAll and gateway interest bugs. 2.15.3-RC.2 also adds a -t --test_reload flag that tells operators whether a config change needs a restart.

Jenkins is shrinking its own war file and rebuilding its UI, one weekly release at a time

◆ Current state

The weekly train is dominated by two long efforts: an incremental redesign of the experimental Manage Jenkins UI, and a deliberate campaign to unbundle plugins from jenkins.war. 2.577 drops bouncycastle, the Command Agent Launcher, JAXB, the SSH server and more, following 2.574's removal of JUnit, Mailer and the matrix plugins. Interleaved security releases ship with no detail beyond a one-line note.

◆ Where it's heading

Two releases cutting 20 MB each signal that unbundling is sustained policy, not a one-off — the core is being reduced toward a minimal server with plugins as an explicit choice. The UI work is methodical and unglamorous: scrollable side panels, sticky build bars, standardised dialogs and command palettes. Neither effort is close to finished.

◆ Prediction

More bundled plugins will be pulled in coming releases, and the experimental Manage Jenkins UI should keep absorbing pages until it can drop the experimental label.

NATS second release candidates add a config reload check and faster redelivery queues.

◆ Current state

NATS keeps the 2.14 and 2.15 lines in step, and on November 6 both got a second release candidate. The RCs make filtered filestore scans skip non-matching messages, stop redelivery queues from copying whole backlogs on each dequeue, and fix AckAll and gateway interest bugs. 2.15.3-RC.2 also adds a -t --test_reload flag that tells operators whether a config change needs a restart.

◆ Where it's heading

The project is in a hardening stretch on both lines, with JetStream efficiency and correctness fixes landing alongside small operator tools. Account-hash subject mappings from RC1 remain the main new routing feature heading to release.

◆ Prediction

Expect 2.15.3 and 2.14.10 final releases shortly, carrying the RC2 fixes and the reload check.
