 The project uses GitHub Actions for continuous integration. The testing workflows are defined in the following files:
 
-- `.github/workflows/ubuntu-tests.yml`: Runs tests on Ubuntu for Python versions 3.9 through 3.12.
+- `.github/workflows/ubuntu-tests.yml`: Runs tests on Ubuntu for Python versions 3.10 through 3.13.
 - `.github/workflows/windows-tests.yml`: Runs that on Windows
 
 These workflows are triggered on push and pull request events to the `main` branch, ignoring changes to the `aider/website/**` and `README.md` files.
