 - Sessions/reset model recompute: clear stale runtime model, context-token, and system-prompt metadata before session resets recompute the replacement session, so resets pick up current defaults and explicit overrides instead of reusing old runtime model state. (#41173) thanks @PonyX-lab.
 - Browser/Browserbase 429 handling: surface stable no-retry rate-limit guidance without buffering discarded HTTP 429 response bodies from remote browser services. (#40491) thanks @mvanhorn.
 - Gateway/auth: allow one trusted device-token retry on shared-token mismatch with recovery hints to prevent reconnect churn during token drift. (#42507) Thanks @joshavant.
+- Channels/allowlists: remove stale matcher caching so same-array allowlist edits and wildcard replacements take effect immediately, with regression coverage for in-place mutation cases.
