 - Gateway/OpenAI HTTP: restore default operator scopes for bearer-authenticated requests that omit `x-openclaw-scopes`, so headless `/v1/chat/completions` and session-history callers work again after the recent method-scope hardening. (#57596) Thanks @openperf.
 - Gateway/attachments: offload large inbound images without leaking `media://` markers into text-only runs, preserve mixed attachment order for model input/transcripts, and fail closed when model image capability cannot be resolved. (#55513) Thanks @Syysean.
 - Telegram/outbound chunking: use static markdown chunking when Telegram runtime state is unavailable so long outbound Telegram messages still split correctly after cold starts. (#57816) Thanks @ForestDengHK.
+- Update/Corepack: disable interactive Corepack download prompts during update preflight install unless `COREPACK_ENABLE_DOWNLOAD_PROMPT` is already explicitly set, so `openclaw update` can fetch the repo-pinned pnpm version non-interactively. (#61456) Thanks @p6l-richard.
