langchain-anthropic==1.3.3

LangChain just patched critical bugs that were breaking Claude 3 integrations for developers.

Deep Dive

LangChain has released version 1.3.3 of its Anthropic integration, fixing key issues that prevented proper use of Claude 3's new 'effort="max"' reasoning mode and beta headers. The update also introduces a new ContextOverflowError for better token management and adds text_inputs/text_outputs tracking in model profiles. This patch resolves integration problems developers faced immediately after Anthropic's major Claude 3 model launch last week.

Why It Matters

Developers building with Claude 3 can now properly implement advanced reasoning features without workarounds or broken integrations.
