OpenClaw Update: Key Changes in Version 2026.5.6

The recent release of OpenClaw v2026.5.6 brings important updates aimed at enhancing the stability and functionality of the software. This version focuses on refining configurations and improving the handling of fetch requests, ensuring a smoother experience for developers and users alike.

What Changed

In this update, several key fixes have been implemented:

• Doctor/OpenAI Config: The legacy Codex route rewrite has been removed from the 2026.5.6 release branch, ensuring that existing OpenAI model configurations remain intact unless a supported repair path is applied.
• Plugins/Runtime Fetch: Third-party symbol metadata is now dropped from plain request header dictionaries before being passed into native fetch or Headers. This change prevents the rejection of valid plugin requests, addressing issue #77846.
• Debug Proxy: Captured fetch header dictionaries are now normalized prior to replaying requests, which prevents failures in debug-proxy fetches due to symbol metadata from caller-owned header objects.
• Web Fetch: The cleanup of bound guarded dispatchers after request timeouts has been improved, allowing timed-out fetches to return tool errors instead of leaving Gateway tool lanes active, resolving issue #78439.

Why It Matters

These updates are crucial for developers using OpenClaw, as they enhance the reliability of configurations and the efficiency of fetch operations. By preserving existing configurations and improving the handling of requests, users can expect a more stable development environment, reducing potential disruptions and increasing productivity.
