Jenkins 2.572, tagged jenkins-2.572, was published on July 7, 2026, with the most relevant platform change in its deserialization defaults. For data teams that run ETL jobs, crawlers, CMS publishing steps, or batch orchestration through Jenkins controllers, this release is mainly about narrowing what persisted configuration and plugin state can load by default.

Jenkins 2.571 was published on July 1, 2026, as a regular weekly release, not a prerelease. For data platform operators, the central change is the bundled script-security update to 1402.1405, because controller side script policy sits near pipeline job logic, shared libraries, and administrative Groovy.

Jenkins 2.570 was published on June 23, 2026, with a compact set of fixes for operators who use Jenkins around data platform builds, batch jobs, and deployment pipelines. The most useful change is SSH key discovery: Jenkins now searches the default ECDSA and Ed25519 key locations, which reduces one common source of brittle agent or remote access setup.
