langchain-core==1.6.7
LangChain released langchain-core 1.6.7, adding OpenAI redacted content support in Bedrock Converse outputs, Python 3.14 compatibility hardening, and dependency updates.
Why this signal matters
The langchain-core 1.6.7 patch release addresses two core fixes: ensuring OpenAI redacted content is included in v1 output for Bedrock Converse integrations, and hardening inspect.signature handling for Python 3.14. It also updates several dependencies within libs/core, including urllib3 (bumped to 2.8.0), tornado (bumped to 6.5.9), and notebook (bumped to 7.6.3).
Actionable summary
langchain-core 1.6.7 includes fixes for Bedrock Converse v1 output to include OpenAI redacted content, hardens Python 3.14 compatibility around inspect.signature, and bumps dependencies for urllib3, tornado, and notebook.
