Windmill
Windmill is dismantling the paywall between itself and the data stack
A side-by-side editorial comparison of k0s and vdiffr — release velocity, themes, recent moves, and the top alternatives to consider.
k0s keeps four Kubernetes branches patched in lockstep, one backport at a time.
The release feed is four maintenance branches — 1.33 through 1.36 — moving in near-formation, plus a 1.37 alpha collecting the unbackported work. Almost every entry is a list of bot-authored bumps: Kubernetes patch versions, etcd, containerd, Calico, Traefik, CoreDNS, kube-router, Alpine and Go. The few human-authored items are small operational fixes, such as keeping the konnectivity server count above zero, distinguishing pending from performed restarts in Autopilot, and omitting an anonymous-auth default when the authentication config already sets it.
vdiffr finished its job in 2021 and has been tracking compilers ever since.
vdiffr generates deterministic SVG snapshots so plot changes show up as test failures. Its recent history is almost entirely toolchain: UCRT Windows compatibility twice, a revert to C++11 to work around a GCC issue, and renaming the internal SVG device so it stops colliding with svglite. The only functional additions in view are snapshot variants in 1.0.8 and a testthat fix so snapshots are no longer auto-deleted when a test errors or skips. The last release was October 2024.

This is a distribution whose product is currency and consistency: the same fix reaches every supported branch within days, and the component matrix stays close to upstream. Autopilot is the one area receiving actual behavior work rather than version bumps, which is where a self-managing cluster story would have to come from. The 1.37 alpha line is where riscv64 support and larger refactors are accumulating.
Expect the 1.37 line to move from alpha toward a release candidate with the riscv64 and etcd 3.7 work carried forward, while 1.33 through 1.36 continue their weekly bump cadence.

The package reached its intended shape at 1.0.0, when snapshot management moved to testthat and vdiffr shed most of its own R and JavaScript code to become a reproducible SVG engine and nothing more. There is not much left to add to that, and the release stream since reads accordingly: it moves when a compiler, an R version, or testthat moves. For a testing dependency this is a healthy end state, though it does mean the package inherits whatever the graphics engine does to snapshot stability.
The entries do not support predicting a feature release. The likely next change is a compatibility fix prompted by a compiler or a testthat change, as every release since 1.0.2 has been.
