GravityKit
GravityKit ships weekly across a whole plugin suite, with an MCP server now part of the lineup.
A side-by-side editorial comparison of runc and GoCD — release velocity, themes, recent moves, and the top alternatives to consider.
runc now publishes an end-of-life calendar, and three branches shipped the same CVE fix in two days.
1.5.0 in June was the first stable release of the 1.5.z series and the third under runc's formal release and support policy: 1.2.z and earlier are unsupported, 1.3.z receives only high-severity CVE fixes until the end of October 2026, and 1.4.z is limited to security and significant bugfixes. A month later 1.5.1 fixed a real-world regression — the maskPaths optimisation from 1.5.0-rc.3 broke tmpfs mounts with nr_inodes=1 on Ubuntu 20.04 kernels. In mid-June, CVE-2026-41579 was fixed simultaneously across 1.3.6, 1.4.3 and 1.5.0-rc.3 and released with no embargo.
GoCD's changelog is one maintainer keeping a 2010s CI server running on current runtimes.
The visible work is almost entirely platform upkeep, and nearly all of it is authored by a single contributor. The baseline has been walked forward repeatedly — Java 17 minimum, then building and packaging on Java 21, then Java 21 as the hard minimum with macOS x64 support dropped — while container images moved from Alpine and CentOS Stream to Wolfi and Chainguard, Rails went from 6.1 through 7.1, and Hamcrest was replaced by AssertJ across the test suite. 26.1.0 is the exception in substance: it carries security fixes described as affecting all prior GoCD versions, with an explicit recommendation to upgrade as soon as possible.

The project is behaving like infrastructure with a contract. Publishing dated support windows and shipping a coordinated fix across every live branch on the same day is the operating posture of a component that sits under every container on a host, where operators need to know what they are still entitled to. The CVE itself is instructive: a /dev symlink escape in the same family as three earlier CVEs, found by re-auditing the rootfs preparation code that had been hardened before.
1.5.0's notes state that a 1.6.0 is expected in late October 2026, which is also when 1.3.z support ends — so the next milestone is that pairing. Expect 1.5.z patches until then.

This is a mature product in custodial maintenance rather than development. The pattern across releases is dependency deduplication, dead code removal, deprecation cleanup and base image swaps — the work that keeps a large Rails and Java codebase installable and patchable on current operating systems. Feature entries are rare enough that their absence, rather than any particular change, is the signal.
Given the security advisory in 26.1.0 covers all earlier versions and the release notes point offsite for detail, the practical next step for operators is that upgrade. The entries show no queued feature work to project from.
