[Release] openclaw/openclaw v2026.5.5: openclaw 2026.5.5

OpenClaw v2026.5.5 is a maintenance release focused on fixing critical bugs across multiple messaging platforms (Feishu, LINE, Telegram, Discord, Matrix, Slack), improving control UI responsiveness and session management, resolving provider integration issues (xAI/Grok, Fireworks), and enhancing diagnostic tools. Key improvements include fixing message routing, webhook validation, tool progress rendering, approval delivery retries, and heartbeat timeout handling. The release also addresses plugin management, media handling, and gateway stability issues.

Key Points

• •Fixed Feishu topic session routing by hydrating missing native topic starter thread IDs before session routing to keep first turns and follow-ups in the same session
• •Enhanced LINE webhook validation to reject `dmPolicy: "open"` configs without wildcard `allowFrom` to prevent silent blocking of DMs
• •Improved Telegram/Codex message-tool progress rendering to avoid duplicating item/tool draft lines and keep progress visible
• •Fixed xAI/Grok integration by removing OpenAI-style reasoning effort controls and clamping thinking profile to `off` for native Grok Responses models
• •Implemented Matrix approval delivery retry logic (up to 3 times with backoff) to handle transient send failures
• •Fixed Discord heartbeat ACK timeout measurement to prevent false reconnect loops and improved control command authorization routing
• •Enhanced Control UI with responsive session details, checkpoint history cards, and performance optimizations for slow history payloads
• •Fixed Windows file permission issues for `exec-approvals.json` with guarded copy fallback while preserving security safeguards
• •Improved iOS pairing with support for `ws://` connects on private LAN and `.local` gateways while maintaining `wss://` for public routes
• •Fixed plugin diagnostics messaging to explain TypeScript packaging issues and guide users to update/reinstall plugins
