Druid 38 drops Java 17, recommends Java 25 and took longer to arrive than its predecessors
A side-by-side editorial comparison of runc and Tekton Pipelines — release velocity, themes, recent moves, and the top alternatives to consider.
runc 1.6.0-rc.1 lifts the 1024-CPU limit and refuses settings it used to quietly ignore
The 1.6.0 cycle opened on October 6 with a first release candidate that is mostly cleanup: deprecated libcontainer APIs removed, Go 1.26 now required, urfave/cli moved from v1 to v3, and the binary about 15% smaller on amd64. The changes with operational weight are that cpuAffinity and NUMA memoryPolicy no longer stop at 1024 CPUs or nodes, and that a container asking for a read-only rootfs without its own mount namespace is now refused. Eleven days earlier 1.5.2 worked around a kernel bug, present since v6.17, that corrupted memory inside runc and caused random crashes on cgroup v2. It also stopped runc exec --cgroup from escaping into a sibling cgroup.
Tekton 1.18 LTS lets a Task finish its steps and still fail.
v1.18.0, an LTS release, adds continueAndFail for step.onError: remaining steps run, then the TaskRun fails. Controller-managed labels become immutable through the webhook, and a truncation bug in large OCI-resolved bundles is fixed. On October 23 five maintained branches, from v1.6.x to v1.17.x, received the same Go 1.27.3 image bump, and v1.6, v1.9 and v1.12 also got a vendor tarball fix.

The project keeps converting silent behaviour into explicit behaviour. Read-only requests that were ignored now fail, a umask that was dropped is now honoured, and poststart hooks moved to conform to the runtime spec. The same maintainers are shrinking the surface underneath, dropping the deprecated API and the high-level cilium/ebpf path, which took roughly 7.5% off the 1.5.2 binary. Stricter behaviour plus a smaller dependency set is what a component under every container host would be expected to do between majors.
1.5.0's notes pointed to a 1.6.0 in late October 2026, and the feed so far shows only rc.1, so further release candidates or the final are the next entries to expect. The refused read-only configurations are the change most likely to surface as user reports during testing.
v1.18.0, an LTS release, adds continueAndFail for step.onError: remaining steps run, then the TaskRun fails. Controller-managed labels become immutable through the webhook, and a truncation bug in large OCI-resolved bundles is fixed. On October 23 five maintained branches, from v1.6.x to v1.17.x, received the same Go 1.27.3 image bump, and v1.6, v1.9 and v1.12 also got a vendor tarball fix.
This cycle is quieter than the security-context change in v1.16. New capability is small and aimed at real pipeline behavior, such as collecting all test results before failing, while most of the release effort goes to keeping many branches current. Making labels immutable fits the same theme as v1.16: tightening what users can change on objects the controller owns.
Expect more same-day patch sets across the LTS branches, since that pattern now repeats. No further end-of-life move appears in these entries, so timing for retiring older branches is unclear.
