Anthropic's claude-code released v2.1.266, fixing a regression in LLM-gateway and proxy setups related to the `CLAUDE_CODE_USE_GATEWAY` environment variable.

READY TO POST:

anthropic's claude-code just dropped v2.1.266, looks like it fixes a pretty annoying bug with their llm-gateway setups and a specific env var. good for those running proxies!

if you're using claude-code with an llm-gateway or proxy, good news: v2.1.266 is out, squashing a bug where `claude_code_use_gateway` was forcing sign-in improperly. worth updating.

## What's changed

- Fixed a 2.1.265 regression affecting LLM-gateway and proxy setups: the undocumented `CLAUDE_CODE_USE_GATEWAY` environment variable, previously ignored unless `ANTHROPIC_BASE_URL` and `ANTHROPIC_AUTH_TOKEN` were both set, began forcing Cloud-gateway sign-in on its own in 2.1.265, so configurations that set it alongside an API key, `apiKeyHelper`, or custom auth headers failed every request with "Not signed in to the Cloud gateway". The variable on its own is ignored again; no configuration change is needed
