@@ -33,6 +33,7 @@ Docs: https://docs.openclaw.ai
 - Cron: add `failureAlert.includeSkipped` and `openclaw cron edit --failure-alert-include-skipped` so persistently skipped jobs can alert without counting skips as execution errors or affecting retry backoff. Fixes #60846. Thanks @slideshow-dingo.
 - Cron: invalidate stale pending runtime slots after live or offline `jobs.json` schedule edits, while preserving due slots for formatting-only rewrites. Fixes #27996 and #71607; carries forward #71651. Thanks @xialonglee and @fagnersouza666.
 - Cron: keep legacy flat `jobs.json` rows loadable while comparing split-state schedule identities, so old cron stores do not crash before in-memory hydration can normalize them. Thanks @codex.
+- Cron/Telegram: preserve direct-chat thread IDs and optional account IDs when inferring reminder delivery from Telegram direct-thread session keys. Fixes #44270; carries forward #44325, #44351, #44412, and #72657. Thanks @RunMintOn, @arkyu2077, @0xsline, and @vincentkoc.
 - Cron: omit synthetic `delivery.resolved` errors from `--no-deliver` run records while preserving explicit no-deliver target traces for agent-initiated messages. Fixes #72210; carries forward #72219. Thanks @hatemclawbot-collab and @xydigit-sj.
 - Cron: classify isolated runs as errors from structured embedded-run execution-denial metadata, with final-output marker fallback for `SYSTEM_RUN_DENIED`, `INVALID_REQUEST`, and approval-binding refusals, so blocked commands no longer appear green in cron history. Fixes #67172; carries forward #67186. Thanks @oc-gh-dr, @hclsys, and @1yihui.
 - Onboarding/GitHub Copilot: add manifest-owned `--github-copilot-token` support for non-interactive setup, including env fallback, tokenRef storage in ref mode, saved-profile reuse, and current Copilot default-model wiring. Refs #50002 and supersedes #50003. Thanks @scottgl9.
