@@ -57,6 +57,7 @@ Docs: https://docs.openclaw.ai
 - Browser/Remote CDP ownership checks: skip local-process ownership errors for non-loopback remote CDP profiles when HTTP is reachable but the websocket handshake fails, and surface the remote websocket attach/retry path instead. (#15582) Landed from contributor (#28780) Thanks @stubbi, @bsormagec, @unblockedgamesstudio and @vincentkoc.
 - Browser/Profile attach-only override: support `browser.profiles.<name>.attachOnly` (fallback to global `browser.attachOnly`) so loopback proxy profiles can skip local launch/port-ownership checks without forcing attach-only mode for every profile. (#20595) Thanks @unblockedgamesstudio and @vincentkoc.
 - Browser/Act request compatibility: accept legacy flattened `action="act"` params (`kind/ref/text/...`) in addition to `request={...}` so browser act calls no longer fail with `request required`. (#15120) Thanks @vincentkoc.
+- Browser/Act stale target recovery: retry one Chrome `act` request without `targetId` after `404: tab not found` so stale relay tab IDs can self-heal without requiring an immediate manual `tabs` refresh. (#30739) Thanks @Sid-Qin.
 - Browser/Extension relay stale tabs: evict stale cached targets from `/json/list` when extension targets are destroyed/crashed or commands fail with missing target/session errors. (#6175) Thanks @vincentkoc.
 - CLI/Browser start timeout: honor `openclaw browser --timeout <ms> start` and stop by removing the fixed 15000ms override so slower Chrome startups can use caller-provided timeouts. (#22412, #23427) Thanks @vincentkoc.
 - Browser/CDP startup diagnostics: include Chrome stderr output and a Linux no-sandbox hint in startup timeout errors so failed launches are easier to diagnose. (#29312) Thanks @veast.
