Helm
v3.21.0Kubernetes CoreHelm v3.21.0 bumps Kubernetes client libs to v1.36, patches OpenTelemetry CVEs, fixes OCI index chart pulling, and corrects nil value preservation in chart merging. Helm v3 EOL is approaching.
securityUpgrade immediately to patch OpenTelemetry CVEs
OpenTelemetry packages were patched specifically to address CVEs. If you're running Helm in CI/CD pipelines or as part of automation tooling, upgrade to v3.21.0 now. Don't wait for the next patch release.
breakingPlan your Helm v4 migration — v3 EOL is real
The release explicitly warns that Helm v3 is approaching end-of-life. This is not a distant concern — v3.22.0 targets Kubernetes v1.37 and v3.21.1 is just a bug fix release. Start evaluating Helm v4 changes now, especially if you maintain custom plugins or automation built around Helm's CLI or Go SDK.
enhancementTest OCI index-based chart pulls if you use multi-arch registries
The fix for pulling charts from OCI indices means setups using image index manifests (common in multi-arch environments) should now work reliably. If you previously worked around this with direct digest references or manifest-specific tags, revisit those workarounds — they may no longer be necessary.
