llm-anthropic 0.27

Simon Willison released llm-anthropic 0.27, an Anthropic plugin for LLM, to ensure compatibility with the anthropic v1.0.0 Python library, which switched from httpx to httpx2. The update was prompted by Anthropic's migration guide and implemented via a pull request generated by Claude Code's Fable 5 model.

Release: llm-anthropic 0.27 https://github.com/simonw/llm-anthropic/releases/tag/0.27 This release of the Anthropic plugin for LLM https://llm.datasette.io/ mainly provides compatibility with the recently released anthropic v1.0.0 https://github.com/anthropics/anthropic-sdk-python/releases/tag/v1.0.0 Python library, which switches from httpx to httpx2 https://github.com/pydantic/httpx2 . OpenAI made the same change in their v3.0.0 release https://github.com/openai/openai-python/releases/tag/v3.0.0 two weeks ago. Anthropic provide this migration guide https://github.com/anthropics/anthropic-sdk-python/blob/v1.0.0/MIGRATION.md for upgrading to 1.0, so I prompted Fable 5 in Claude Code with: Upgrade to anthropic =1 - read https://raw.githubusercontent.com/anthropics/anthropic-sdk-python/refs/heads/main/MIGRATION.md and get the tests passing Here's the resulting PR https://github.com/simonw/llm-anthropic/pull/84 .
