edge-25.10.3

Overall status: NOT RECOMMENDED, use edge-25.10.7 instead

Cautions

This release includes one breaking change: it removes the ip_port_subscribers metric and replaces it with the lower-cardinality workload_subscribers metric.

Changes

This release removes the linkerd.io/proxy-root-parent and linkerd.io/proxy-root-parent-kind labels added to injected pods in edge-25.10.2. It also fixes a potential deadlock that could result in leaked tasks and unneeded memory consumption, and allows configuring the destination controller's stream queue capacity. The default remains 100 for the moment; lower values may be better for improving responsiveness to readiness and liveness issues.
