checkpoint==2.0.0

The diff only shows a version number change from 1.0.14 to 2.0.0 in the pyproject.toml file. There are no actual code changes provided in the diff to generate release notes from.

To create meaningful release notes, I would need to see the actual code changes between these versions. If you can provide the complete diff of code changes, I'll be happy to generate the release notes following the requested format.
