[Release] openclaw/openclaw v2026.5.6: openclaw 2026.5.6

OpenClaw v2026.5.6 addresses critical OAuth routing issues, plugin fetch header handling, and debug proxy normalization. The release reverts a problematic repair from v2026.5.5 that incorrectly rewrote OpenAI Codex OAuth routes, which could break GPT-5.5 setups. Additional fixes improve fetch request handling across plugins, debug proxies, and web requests to prevent symbol metadata rejection and resource cleanup issues.

Key Points

• •Revert OpenAI Codex OAuth route rewriting from v2026.5.5 that broke `openai-codex/*` ChatGPT/Codex OAuth routes by converting them to `openai/*` API-key routes
• •Run `openclaw models set openai-codex/gpt-5.5 && openclaw config validate` if v2026.5.5 changed your default model to restore Codex OAuth routing
• •Remove third-party symbol metadata from request header dictionaries before passing to native `fetch` or `Headers` to prevent SDK and proxy fetch rejection
• •Normalize captured fetch header dictionaries in debug proxy before replaying requests to prevent symbol metadata from caller-owned headers causing failures
• •Implement guarded dispatcher cleanup bounds after request timeouts to return tool errors instead of leaving Gateway tool lanes active
• •Fixes affect OAuth-only GPT-5.5 setups, plugin runtime fetch operations, debug proxy request replay, and web fetch timeout handling
• •Recovery documentation available at docs.openclaw.ai/providers/openai#check-and-recover-codex-oauth-routing
