 ## Changelog
 
+### v0.21.3 — Config Apply Infra Push + Fixes (2026-02-20)
+- **Push infra backup after config apply**: After a successful `POST /api/config/apply`, the controller immediately pushes an infra backup to the Hub so the config sync status updates right away.
+- **Fix double "v" prefix in startup event**: "Controller elindult (vv0.21.2)" → "Controller elindult (v0.21.3)".
+
 ### v0.21.2 — Config Apply Bind Mount Fix (2026-02-20)
 - **Fix config apply on Docker bind mounts**: `POST /api/config/apply` failed with "device or resource busy" because `os.Rename()` doesn't work on bind-mounted files. Now falls back to direct write when rename fails.
