OpenClaw 2026.6.5 Update

OpenClaw version 2026.6.5 was updated with a focus on improving stability in real-world usage environments.

Key updates:

• Introduction of free Parallel Search: A managed web search feature is now available without needing a separate API key or account setup. This allows agents to check the latest documentation, investigate API changes, and conduct research before code changes, all without connecting to external tools.
• Enhanced agent execution recovery: Improved normalization of MCP (Model Context Protocol) tool results to prevent 400 errors from the Anthropic API and contamination of session history. Additionally, Anthropic's extended-thinking sessions now recover better after prompt cache expiration or gateway restarts.
• Channel response and communication stability: Fixed bugs related to response delays, thread maintenance, and state preservation when integrating with various messenger platforms such as Discord, WhatsApp, iMessage, Mattermost, and Feishu, improving communication reliability.
• System stability: Reduced vulnerabilities in model and provider configurations and strengthened boundaries between tools and gateways, further stabilizing operation across app, mobile, and node environments.
