Hitch hikers guide to Headlamp 0.42.0
Deep-link support was added for pod terminals (?view=exec) and log views (?view=logs), letting users bookmark or share direct links to specific UI states. Resources can now be searched by label in all list views, the Log Viewer gains a severity filter dropdown, and a delete button has been added directly to the plugins list. Node Details received two new sections for pod capacity usage and resource allocation, and the Resource Map now renders status badges on plugin-provided nodes and includes previously missing configuration resources. GRPCRoute details reach full parity with HTTPRoute, and a guided form-based resource creation UI (starting with Pods) is now available alongside the YAML editor.
On the reliability side, a silent cache desync that caused permanently stale cluster data was fixed, along with a lock-order inversion deadlock that could freeze WebSocket connections under load, and a wave of React hooks rule violations across more than a dozen frontend components. Several backend panics were fixed in port-forwarding, kubeconfig parsing, cache key generation, and Helm chart type handling, alongside debounced log aggregation to prevent UI freezes in All Pods mode. Security hardening includes path traversal prevention in the service proxy and dependency bumps.
