k0s vs werf: at a glance
What is k0s?
k0s ships another four-branch patch round, with an IPv6 service CIDR fix on 1.37 and 1.36.
On November 3 k0s released v1.37.2, 1.36.6, 1.35.10 and 1.34.13 within minutes of each other. The 1.37 and 1.36 releases remove a size limit on IPv6 service CIDRs and update containerd to 2.3.6; 1.37.2 also bumps kine, ORAS and troubleshoot. The 1.35 and 1.34 branches take only Kubernetes patch updates.
What is werf?
werf v3.12.2 lets --values and --set override secret values and fixes RUN mount rebuilds.
werf's v3.12.2, on alpha and beta, is a fix release: --values and --set can now override secret values, Dockerfile builds rebuild when a RUN bind-mount source changes, and a lock timeout deadlock is gone. v2.84.1 on alpha backports the Docker Hub login and saved-plan fixes and stops uninstall hangs. v3.12.1 remains the first v3 release in the feed on the stable and rock-solid channels.

k0s
5.0INFRA · APIS
k0s ships another four-branch patch round, with an IPv6 service CIDR fix on 1.37 and 1.36.
◆ Current state
On November 3 k0s released v1.37.2, 1.36.6, 1.35.10 and 1.34.13 within minutes of each other. The 1.37 and 1.36 releases remove a size limit on IPv6 service CIDRs and update containerd to 2.3.6; 1.37.2 also bumps kine, ORAS and troubleshoot. The 1.35 and 1.34 branches take only Kubernetes patch updates.
◆ Where it's heading
k0s now maintains four branches on a shared patch cadence, roughly one coordinated round a week after the 1.37 line opened on October 27. Fixes and dependency updates land on the newest two branches, while older ones receive only Kubernetes patches, which indicates where active support is concentrated.
◆ Prediction
Expect the next coordinated round to follow upstream Kubernetes patch releases, with 1.34 likely to stop receiving updates as 1.37 matures.
werf
5.0INFRA · APIS
werf v3.12.2 lets --values and --set override secret values and fixes RUN mount rebuilds.
◆ Current state
werf's v3.12.2, on alpha and beta, is a fix release: --values and --set can now override secret values, Dockerfile builds rebuild when a RUN bind-mount source changes, and a lock timeout deadlock is gone. v2.84.1 on alpha backports the Docker Hub login and saved-plan fixes and stops uninstall hangs. v3.12.1 remains the first v3 release in the feed on the stable and rock-solid channels.
◆ Where it's heading
After v3 first reached every channel, the two lines keep moving in step, with shared fixes landing the same day. v3 is getting more of the deploy and Dockerfile behavior changes while v2 receives fix-only patches, which fits v3 becoming the main line, though the entries don't say so.
◆ Prediction
Expect v3.12.2 to move up to stable and rock-solid as v3.12.1 did. A migration note for v2 users would confirm the shift.
