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 werf?

Four channels, one fix stream — werf's releases are mostly concurrency repairs.

werf publishes the same work across alpha, beta, ea, and stable channels plus a 3.x dev line, so a single fix surfaces three or four times under different version numbers. The substance in this window is almost entirely build-engine concurrency: parallel recovery failures, races in Dockerfile builds, concurrent stderr access, serialized base image pulls, retries when a cached image id goes missing. New function is thin — a case-insensitive-condition-tracking feature gate, a build time summary in debug mode, and a registry-side cleanup report.

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.

Four channels, one fix stream — werf's releases are mostly concurrency repairs.

◆ Current state

werf publishes the same work across alpha, beta, ea, and stable channels plus a 3.x dev line, so a single fix surfaces three or four times under different version numbers. The substance in this window is almost entirely build-engine concurrency: parallel recovery failures, races in Dockerfile builds, concurrent stderr access, serialized base image pulls, retries when a cached image id goes missing. New function is thin — a case-insensitive-condition-tracking feature gate, a build time summary in debug mode, and a registry-side cleanup report.

◆ Where it's heading

The 3.x dev line is accumulating what 2.x is stabilizing, and the one genuinely new thing in it is a deno binary embedded into werf releases behind a build tag. That is the only entry pointing anywhere beyond maintenance, and it is gated, so its intent is not yet stated. Otherwise the pattern is a mature build tool hardening buildah paths under parallelism, which is where self-hosted CI hits it hardest.

◆ Prediction

The embedded deno work is the thread to watch — if it stays behind its build tag it is an experiment, and if 3.x ships it on by default it implies a scripting surface for deployment.
