Helm

Helm’s GitHub releases page documents breaking changes per major version, and the Helm 2 to Helm 3 migration is the canonical example of why this matters: the removal of Tiller, the cluster-side daemon that held release state, invalidated every existing deployment workflow overnight. The 3.0.0 release notes carried explicit migration guidance; teams that skipped them found themselves debugging a cluster-state mismatch with no clear path back.

The page functions as the chart-tooling layer’s companion to Kubernetes release notes. When a Kubernetes minor version deprecates an API, the corresponding Helm release notes typically document how chart authors need to respond. Reading both together is the practical minimum for anyone running production clusters across version boundaries.
