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.
SavvyCal keeps polishing scheduling ergonomics on a slow, steady cadence.
SavvyCal is a scheduling tool competing on booking-experience quality. Its changelog moves at a measured pace — roughly one release a month — and the recent run is a series of contained refinements: duplicating workflows, locking links against last-minute changes, per-event buffer control, multi-language booking pages, and improvements to booking on behalf of others.

Interleaved security releases ship with no detail beyond a one-line note.
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.
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.

The through-line is control and convenience for the host and for assistants who schedule for others: workflow reuse, guardrails on rescheduling, richer contact records, and localized booking pages. Nothing here shifts the product's category; it is deliberate incrementalism aimed at making the existing scheduling surface more flexible and reliable.
Expect more of the same — small, self-contained booking and workflow refinements on a monthly rhythm — absent any signal of a larger platform or AI move in these entries.
