This change updates the version constraint for the langchain package in the pyproject.toml file of the backend-agent. Previously, langchain was limited to versions between 0.3.0 and 0.4.0, but now it can use versions up to 1.2.0. This expands the range of potential features and fixes that can be utilized from more recent versions of the package.

Walkthrough

  • Chore: Updated version constraints for langchain from <0.4.0 to <1.2.0 to allow compatibility with newer versions and take advantage of any improvements, features, or bug fixes introduced after version 0.4.0.

Version constraint inconsistency detected. The langchain package allows versions up to <1.2.0, but related packages (langchain-community, langchain-core, langchain-text-splitters) are constrained to <0.4.0. This creates a potential compatibility issue where langchain could be upgraded to a version that's incompatible with its dependencies.

Consider aligning all langchain-related packages to use consistent version ranges:

'langchain>=0.3.0,<0.4.0',
'langchain-community>=0.3.0,<0.4.0',
'langchain-core>=0.3.0,<0.4.0',
'langchain-text-splitters>=0.3.0,<0.4.0',

Or if you need the newer langchain version, update all related packages accordingly to maintain compatibility.
