LangChain Core version 1.5.2 is now available, bringing a targeted bug fix and several routine dependency updates. The most notable change resolves an issue where empty string values in gateway environment variables were not handled correctly, which could lead to unexpected behavior in certain configurations. This fix ensures more robust handling of environment settings for gateway integrations.
In addition, maintenance updates were made to keep the library’s dependencies current. Setuptools has been upgraded from 82.0.0 to 83.0.0 in the core package, and from 80.9.0 to 83.0.0 in the text-splitters package. JupyterLab was also bumped from version 4.5.9 to 4.5.10 in the core package. These updates improve compatibility and incorporate the latest security and performance enhancements.
