OpenClaw v2026.2.15-beta.1 预发布

### Changes - Discord: unlock rich interactive agent prompts with Components v2 (buttons, selects, modals, and attachment-backed file blocks) so for native interaction through Discord. Thanks @thewilloftheshadow. - Discord: components v2 UI + embeds passthrough + exec approval UX refinements (CV2 containers, button layout, Discord-forwarding skip). Thanks @thewilloftheshadow. - Plugins: expose `llm_input` and `llm_output` hook payloads so extensions can observe prompt/input context and model output usage details. (#16724) Thanks @SecondThread. - Subagents: nested sub-agents (sub-sub-agents) with configurable depth. Set `agents.defaults.subagents.maxSpawnDepth: 2` to allow sub-agents to spawn their own children. Includes `maxChildrenPerAgent` limit (default 5), depth-aware tool policy, and proper announce chain routing. (#14447) Thanks @tyler6204. - Slack/Discord/Telegram: add per-channel ack reaction overrides (account/channel-level) to support platform-specific emoji formats. (#17092) Thanks @zerone0x. - Cron/Gateway: add finished-run webhook delivery toggle (`notify`) and dedicated webhook auth token support (`cron.webhookToken`) for outbound cron webhook posts. (#14535) Thanks @advaitpaliwal. - Channels: deduplicate probe/token resolution base types across core + extensions while preserving per-channel error typing. (#16986) Thanks @iyoda and @thewilloftheshadow. ### Fixes - Security: replace deprecated SHA-1 sandbox configuration hashing with SHA-256 for deterministic sandbox cache identity and recreation checks. Thanks @kexinoh. - Security/Logging: redact Telegram bot tokens from error messages and uncaught stack traces to prevent accidental secret leakage into logs. Thanks @aether-ai-agent. - Sandbox/Security: block dangerous sandbox Docker config (bind mounts, host networking, unconfined seccomp/apparmor) to prevent container escape via config injection. Thanks @aether-ai-agent. - Sandbox: preserve array order in config hashing so order-sensitive Docker/browser settings trigger container recreation correctly. Thanks @kexinoh. - Gateway/Security: redact sensitive session/path details from `status` responses for non-admin clients; full details remain available to `operator.admin`. (#8590) Thanks @fr33d3m0n. - Gateway/Control UI: preserve requested operator scopes for Control UI bypass modes (`allowInsecureAuth` / `dangerouslyDisableDeviceAuth`) when device identity is unavailable, preventing false `missing scope` failures on authenticated LAN/HTTP operator sessions. (#17682) Thanks @leafbird. - LINE/Security: fail closed on webhook startup when channel token or channel secret is missing, and treat LINE accounts as configured only when both are present. (#17587) Thanks @davidahmann. - Skills/Security: restrict `download` installer `targetDir` to the per-skill tools directory to prevent arbitrary file writes. Thanks @Adam55A-code. - Skills/Linux: harden go installer fallback on apt-based systems by handling root/no-sudo environments safely, doing best-effort apt index refresh, and returning actionable errors instead of failing with spawn errors. (#17687) Thanks @mcrolly. - Web Fetch/Security: cap downloaded response body size before HTML parsing to prevent memory exhaustion from oversized or deeply nested pages. Thanks @xuemian168. - Config/Gateway: make sensitive-key whitelist suffix matching case-insensitive while preserving `passwordFile` path exemptions, preventing accidental redaction of non-secret config values like `maxTokens` and IRC password-file paths. (#16042) Thanks @akramcodez. - Dev tooling: harden git `pre-commit` hook against option injection from malicious filenames (for example `--force`), preventing accidental staging of ignored files. Thanks @mrthankyou. - Gateway/Agent: reject malformed `agent:`-prefixed session keys (for example, `agent:main`) in `agent` and `agent.identity.get` instead of silently resolving them to the default agent, preventing accidental cross-session routing. (#15707) Thanks @rodrigouroz. - Gateway/Chat: harden `chat.send` inbound message handling by rejecting null bytes, stripping unsafe control characters, and normalizing Unicode to NFC before dispatch. (#8593) Thanks @fr33d3m0n. - Gateway/Send: return an actionable error when `send` targets internal-only `webchat`, guiding callers to use `chat.send` or a deliverable channel. (#15703) Thanks @rodrigouroz. - Control UI: prevent stored XSS via assistant name/avatar by removing inline script injection, serving bootstrap config as JSON, and enforcing `script-src 'self'`. Thanks @Adam55A-code. - Agents/Security: sanitize workspace paths before embedding into LLM prompts (strip Unicode control/format chars) to prevent instruction injection via malicious directory names. Thanks @aether-ai-agent. - Agents/Sandbox: clarify system prompt path guidance so sandbox `bash/exec` uses container paths (for example `/workspace`) while file tools keep host-bridge mapping, avoiding first-attempt path misses from host-only absolute paths in sandbox command execution. (#17693) Thanks @app/juniordevbot. - Agents/Context: apply configured model `contextWindow` overrides after provider discovery so `lookupContextTokens()` honors operator config values (including discovery-failure paths). (#17404) Thanks @michaelbship and @vignesh07. - Agents/Context: derive `lookupContextTokens()` from auth-available model metadata and keep the smallest discovered context window for duplicate model ids, preventing cross-provider cache collisions from overestimating session context limits. (#17586) Thanks @githabideri and @vignesh07. - Agents/OpenAI: force `store=true` for direct OpenAI Responses/Codex runs to preserve multi-turn server-side conversation state, while leaving proxy/non-OpenAI endpoints unchanged. (#16803) Thanks @mark9232 and @vignesh07. - Memory/FTS: make `buildFtsQuery` Unicode-aware so non-ASCII queries (including CJK) produce keyword tokens instead of falling back to vector-only search. (#17672) Thanks @KinGP5471. - Auto-reply/Compaction: resolve `memory/YYYY-MM-DD.md` placeholders with timezone-aware runtime dates and append a `Current time:` line to memory-flush turns, preventing wrong-year memory filenames without making the system prompt time-variant. (#17603, #17633) Thanks @nicholaspapadam-wq and @vignesh07. - Agents: return an explicit timeout error reply when an embedded run times out before producing any payloads, preventing silent dropped turns during slow cache-refresh transitions. (#16659) Thanks @liaosvcaf and @vignesh07. - Group chats: always inject group chat context (name, participants, reply guidance) into the system prompt on every turn, not just the first. Prevents the model from losing awareness of which group it's in and incorrectly using the message tool to send to the same group. (#14447) Thanks @tyler6204. - Browser/Agents: when browser control service is unavailable, return explicit non-retry guidance (instead of "try again") so models do not loop on repeated browser tool calls until timeout. (#17673) Thanks @austenstone. - Subagents: use child-run-based deterministic announce idempotency keys across direct and queued delivery paths (with legacy queued-item fallback) to prevent duplicate announce retries without collapsing distinct same-millisecond announces. (#17150) Thanks @widingmarcus-cyber. - Subagents/Models: preserve `agents.defaults.model.fallbacks` when subagent sessions carry a model override, so subagent runs fail over to configured fallback models instead of retrying only the overridden primary model. - Telegram: omit `message_thread_id` for DM sends/draft previews and keep forum-topic handling (`id=1` general omitted, non-general kept), preventing DM failures with `400 Bad Request: message thread not found`. (#10942) Thanks @garnetlyx. - Telegram: replace inbound `<media:audio>` placeholder with successful preflight voice transcript in message body context, preventing placeholder-only prompt bodies for mention-gated voice messages. (#16789) Thanks @Limitless2023. - Telegram: retry inbound media `getFile` calls (3 attempts with backoff) and gracefully fall back to placeholder-only processing when retries fail, preventing dropped voice/media messages on transient Telegram network errors. (#16154) Thanks @yinghaosang. - Telegram: finalize streaming preview replies in place instead of sending a second final message, preventing duplicate Telegram assistant outputs at stream completion. (#17218) Thanks @obviyus. - Telegram: disable block streaming when `channels.telegram.streamMode` is `off`, preventing newline/content-block replies from splitting into multiple messages. (#17679) Thanks @saivarunk. - Discord: preserve channel session continuity when runtime payloads omit `message.channelId` by falling back to event/raw `channel_id` values for routing/session keys, so same-channel messages keep history across turns/restarts. Also align diagnostics so active Discord runs no longer appear as `sessionKey=unknown`. (#17622) Thanks @shakkernerd. - Discord: dedupe native skill commands by skill name in multi-agent setups to prevent duplicated slash commands with `_2` suffixes. (#17365) Thanks @seewhyme. - Discord: ensure role allowlist matching uses raw role IDs for message routing authorization. Thanks @xinhuagu. - Web UI/Agents: hide `BOOTSTRAP.md` in the Agents Files list after onboarding is completed, avoiding confusing missing-file warnings for completed workspaces. (#17491) Thanks @gumadeiras. - Memory/QMD: scope managed collection names per agent and precreate glob-backed collection directories before registration, preventing cross-agent collection clobbering and startup ENOENT failures in fresh workspaces. (#17194) Thanks @jonathanadams96. - Auto-reply/WhatsApp/TUI/Web: when a final assistant message is `NO_REPLY` and a messaging tool send succeeded, mirror the delivered messaging-tool text into session-visible assistant output so TUI/Web no longer show `NO_REPLY` placeholders. (#7010) Thanks @Morrowind-Xie. - Cron: infer `payload.kind="agentTurn"` for model-only `cron.update` payload patches, so partial agent-turn updates do not fail validation when `kind` is omitted. (#15664) Thanks @rodrigouroz. - TUI: make searchable-select filtering and highlight rendering ANSI-aware so queries ignore hidden escape codes and no longer corrupt ANSI styling sequences during match highlighting. (#4519) Thanks @bee4come. - TUI/Windows: coalesce rapid single-line submit bursts in Git Bash into one multiline message as a fallback when bracketed paste is unavailable, preventing pasted multiline text from being split into multiple sends. (#4986) Thanks @adamkane. - TUI: suppress false `(no output)` placeholders for non-local empty final events during concurrent runs, preventing external-channel replies from showing empty assistant bubbles while a local run is still streaming. (#5782) Thanks @LagWizard and @vignesh07. - TUI: preserve copy-sensitive long tokens (URLs/paths/file-like identifiers) during wrapping and overflow sanitization so wrapped output no longer inserts spaces that corrupt copy/paste values. (#17515, #17466, #17505) Thanks @abe238, @trevorpan, and @JasonCry. - CLI/Build: make legacy daemon CLI compatibility shim generation tolerant of minimal tsdown daemon export sets, while preserving restart/register compatibility aliases and surfacing explicit errors for unavailable legacy daemon commands. Thanks @vignesh07.
