 ## [Unreleased]
 
+## [v0.51.655] — 2026-06-25 — Release XK (live metering stops reloading the session every tick)
+
 ### Fixed
 
 - **Live metering during active streams no longer reloads the session on every usage tick.** The streaming worker now reuses its current session object for `_live_usage_snapshot()` and only falls back to `get_session()` once before the worker has loaded that object. This removes another avoidable global-session-lock touch point while tokens and tool events are streaming, narrowing the lock-contention half of #4918 without changing usage payloads or active-stream state.
