@@ -181,6 +181,7 @@ Docs: https://docs.openclaw.ai
 - Memory/Hybrid recall: when strict hybrid scoring yields no hits, preserve keyword-backed matches using a text-weight floor so freshly indexed lexical canaries no longer disappear behind `minScore` filtering. (#29112) Thanks @ceo-nada.
 - Android/Notifications auth race: return `NOT_AUTHORIZED` when `POST_NOTIFICATIONS` is revoked between authorization precheck and delivery, instead of returning success while dropping the notification. (#30726) Thanks @obviyus.
 - Cron/Reminder session routing: preserve `job.sessionKey` for `sessionTarget="main"` runs so queued reminders wake and deliver in the originating scoped session/channel instead of being forced to the agent main session.
+- Cron/Timezone regression guard: add explicit schedule coverage for `0 8 * * *` with `Asia/Shanghai` to ensure `nextRunAtMs` never rolls back to a past year and always advances to the next valid occurrence. (#30351)
 - Agents/Sessions list transcript paths: resolve `sessions_list` `transcriptPath` via agent-aware session path options and ignore combined-store sentinel paths (`(multiple)`) so listed transcript paths always point to the state directory. (#28379) Thanks @fafuzuoluo.
 - Podman/Quadlet setup: fix `sed` escaping and UID mismatch in Podman Quadlet setup. (#26414) Thanks @KnHack and @vincentkoc.
 - Browser/Navigate: resolve the correct `targetId` in navigate responses after renderer swaps. (#25326) Thanks @stone-jin and @vincentkoc.
