 - `BatteryPool::telemetry_snapshots()` exposes the same per-component health partition (`BatteryPoolSnapshot`).
 
 - The pool telemetry trackers and snapshot types (`BatteryPoolSnapshot`, `PvPoolSnapshot`, `InverterBatteryGroup`, `InverterBatteryGroupStatus`) are now public and re-exported from the crate root.

+## Bug Fixes
+
+- The pool, group, and component telemetry trackers no longer leak their tasks (while logging at error level every tick) once their consumers are gone; normal shutdown is now logged at debug.
+
+- The client now evicts ended per-component telemetry streams from its cache, so a pool recreated on the same client receives telemetry again instead of silently getting none.
