@@ -62,6 +62,7 @@ Docs: https://docs.openclaw.ai
 - Telegram: debounce the first draft-stream preview update (30-char threshold) and finalize short responses by editing the stop-time preview message, improving first push notifications and avoiding duplicate final sends. (#18148) Thanks @Marvae.
 - Telegram: disable block streaming when `channels.telegram.streamMode` is `off`, preventing newline/content-block replies from splitting into multiple messages. (#17679) Thanks @saivarunk.
 - Telegram: keep `streamMode: "partial"` draft previews in a single message across assistant-message/reasoning boundaries, preventing duplicate preview bubbles during partial-mode tool-call turns. (#18956) Thanks @obviyus.
+- Telegram: normalize native command names for Telegram menu registration (`-` -> `_`) to avoid `BOT_COMMAND_INVALID` command-menu wipeouts, and log failed command syncs instead of silently swallowing them. (#19257) Thanks @akramcodez.
 - Telegram: route non-abort slash commands on the normal chat/topic sequential lane while keeping true abort requests (`/stop`, `stop`) on the control lane, preventing command/reply race conditions from control-lane bypass. (#17899) Thanks @obviyus.
 - Telegram: ignore `<media:...>` placeholder lines when extracting `MEDIA:` tool-result paths, preventing false local-file reads and dropped replies. (#18510) Thanks @yinghaosang.
 - Telegram: skip retries when inbound media `getFile` fails with Telegram's 20MB limit and continue processing message text, avoiding dropped messages for oversized attachments. (#18531) Thanks @brandonwise.
