Two branches running in parallel: 3.13 LTS on security patches, 3.14 promoting experiments to stable.
A side-by-side editorial comparison of Istio and Jenkins — release velocity, themes, recent moves, and the top alternatives to consider.
Istio's Ambient mesh hits multi-network beta and the project is unwinding from Google-hosted artifacts.
Recent activity is split across three threads: technical posts (wildcard egress design, namespace multi-tenancy security guidance, and ambient multi-network multicluster reaching beta), governance work (2026 Steering Committee election results, KubeCon EU planning), and infrastructure (announcement that Istio images will leave gcr.io/istio-release by January 2027 due to changes in funding). Release-cadence-wise, the substantive product release in this slate is ambient multi-network multicluster moving to beta in 1.29.
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.

Istio is methodically maturing the Ambient data plane, with multi-network multicluster — historically an Istio strength on the sidecar side — now reaching beta on Ambient with telemetry gaps closed. In parallel, the project is consolidating its operational footprint: container registries and Helm charts are migrating off Google Cloud, suggesting a more independent project posture under the CNCF. Security work is steady (the multi-tenancy MITM advisory).
Expect Ambient multi-network multicluster to reach GA within two minor releases as adoption feedback closes the remaining gaps. The container registry move will spark a stretch of customer-facing docs and migration tooling through 2026 — and likely a similar move for Helm charts and other artifacts within a quarter. Steering committee composition shift toward Solo.io and other major contributors signals continued vendor influence on roadmap priorities.

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.
