The storage autoscaler integrates into the reconcile loop, blocks concurrent rolling restarts during expansion, and supports external tools like KEDA. TLS rotation is triggered by creating a `-new` Secret and requires no CR changes. ARM64 support covers AWS Graviton3, Google Axion, and Azure Cobalt100 instances. The release also deprecates PMM2 monitoring integration, with removal planned for version 1.22.0. ## Full article daily.dev links to this article rather than hosting it.
