:::danger v1/messages routing change
This version starts routing `/v1/messages` requests to the `/responses` API by default. To opt out and continue using chat/completions, set `LITELLM_USE_CHAT_COMPLETIONS_URL_FOR_ANTHROPIC_MESSAGES=true` or `litellm_settings.use_chat_completions_url_for_anthropic_messages: true` in your config.
