Releases: langchain-ai/langchain
langchain-community==0.2.19
langchain-anthropic==0.3.0
Version 0.39.0 of the Anthropic Python SDK enables support for Python 3.13. This involved the deletion of a legacy client.count_tokens method. langchain-anthropic 0.3.0 drops support for token counting via this method on the Anthropic LLM.
Anthropic has replaced this functionality with the client.beta.messages.count_tokens() API. This release adds support for token counting using this API via ChatAnthropic.get_num_tokens_from_messages. This required adding an optional tools parameter to the signature of .get_num_tokens_from_messages.
