Dependencies and platform

  • #4979 upgrades pandas and SQLAlchemy to 2.x and updates affected data-cleaning, database, and integration code for compatibility.
  • #6123 upgrades dbt core and adapters to the dbt 1.10 stack, refreshes related dependencies, and raises the minimum Python version to 3.10.
  • #6127 switches Python package installation in Docker images and CI workflows to uv.
  • #6179 upgrades GitPython to 3.1.62 to address known vulnerabilities.

Fixes and security

  • #6183 suppresses expected WebSocketClosedError noise when terminal clients disconnect.

Maintenance
