 - Discord/ack reactions: keep automatic ACK reaction auth on the active hydrated Discord account so SecretRef-backed and non-default-account reactions stop falling back to stale default config resolution. (#60081) Thanks @FunJim.
 - Telegram/model switching: render non-default `/model` callback confirmations with HTML formatting so Telegram shows the selected model in bold instead of raw `**...**` markers. (#60042) Thanks @GitZhangChi.
 - Plugins/update: allow `openclaw plugins update` to use `--dangerously-force-unsafe-install` for built-in dangerous-code false positives during plugin updates. (#60066) Thanks @huntharo.
+- Control UI/chat: keep the Stop button visible during tool-only execution so abortable runs do not fall back to Send while tools are still running. (#54528) thanks @chziyue.

 - OpenShell and ACP file boundaries: skip symlinks and preserve trusted host-only directories during OpenShell mirror sync, and route ACP attachment reads through the shared attachment cache so local files outside allowed roots are no longer forwarded. (#57693, #57690)
 - Channel/webhook authorization: skip Discord audio preflight transcription for unauthorized guild senders, add a shared pre-auth in-flight guard to Synology Chat webhooks, and validate Microsoft Teams bearer auth before JSON body parsing. (#57695, #57722, #57686)
 - Infra/randomness: replace `Math.random()` in affected identifier and delay-jitter paths with shared secure-random helpers, including UI UUID generation. (#57744)
