OpenClaw v2026.5.6: Critical Fixes Land Day After 2026.5.5 Breaks Codex OAuth

OpenClaw released v2026.5.6 today, a rapid-response patch landing just 24 hours after the 2026.5.5 release — and fixing a significant regression in the process.

The 2026.5.5 Doctor Bug

The most impactful fix reverts part of the 2026.5.5 doctor --fix repair that was rewriting valid openai-codex/* ChatGPT/Codex OAuth routes to openai/*. For users on Codex OAuth-only GPT-5.5 setups, this could break authentication entirely by accidentally moving them onto the API-key route. The fix: if 2026.5.5 already changed your default model, run:

openclaw models set openai-codex/gpt-5.5 && openclaw config validate

Other Fixes in 2026.5.6

  • Plugin fetch: Third-party symbol metadata is now stripped from plain request header dictionaries before being passed into native fetch or Headers, preventing SDK and proxy paths from rejecting valid plugin requests. Fixes #77846, thanks @shakkernerd.

  • Debug proxy: Captured fetch headers are normalized before replay, preventing caller-owned header objects from causing debug-proxy fetches to fail.

  • Web fetch: Bound guarded dispatcher cleanup after request timeouts so timed-out fetches return proper tool errors instead of leaving Gateway tool lanes in a hung state. Fixes #78439, thanks @obviyus.
