What is Gitness?

Harness Open Source last shipped in August 2025, on this feed at least

The feed holds two releases of Harness Open Source, tracked here as Gitness. v3.2.0 in May 2025 added Git LFS, default reviewers through branch rules and a Revert PR option; v3.3.0 that August added tag rules, a PR dashboard upgrade with favourite repositories, and a fix for a Git LFS upload path flaw. Nothing newer appears here.

What is runc?

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.

Harness Open Source last shipped in August 2025, on this feed at least

◆ Current state

The feed holds two releases of Harness Open Source, tracked here as Gitness. v3.2.0 in May 2025 added Git LFS, default reviewers through branch rules and a Revert PR option; v3.3.0 that August added tag rules, a PR dashboard upgrade with favourite repositories, and a fix for a Git LFS upload path flaw. Nothing newer appears here.

◆ Where it's heading

Both releases deepen code-hosting governance: branch rules, then tag rules, plus review routing through Code Owners. That is parity work against established Git hosts rather than a new direction. With entries more than a year old, the feed shows where the project was heading in 2025, not where it is now.

◆ Prediction

The entries do not support a confident call: there is no release in this feed after v3.3.0, so it is unclear whether the project slowed or the feed stopped tracking it.

runc 1.6.0-rc.1 lifts the 1024-CPU limit and refuses settings it used to quietly ignore

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
