What happened
Prometheus release notes (3.11.0-rc.0, 3.10.0 and related tags). Key changes: deprecations in Hetzner service discovery labels (use __meta_hetzner_robot_datacenter and new hcloud location labels; hcloud labels will stop working after 2026-07-01), promtool now sends debug output to stderr, and AWS service discovery gained an ElastiCache role. A new distroless Docker image variant is available (prom/prometheus:<tag>-distroless) that uses UID/GID 65532 (nonroot) and removes VOLUME; busybox remains the default. Migration guidance: adjust named volume ownership (example chown command) or bind-mount
