+
+2. Add a summary of the changes to [the changelog](https://github.com/MIT-LCP/wfdb-python/blob/main/docs/changes.rst). You may also need to update [the documentation](https://github.com/MIT-LCP/wfdb-python/tree/main/docs). For example, if function arguments have been updated, this change will need to be captured. Open a pull request to merge these changes to the main branch.

+3. After the pull requests above have been merged, go to https://github.com/MIT-LCP/wfdb-python/releases and click "Draft new release" to create a new tag/release of the package. Set the tag to the new version number and draft the release notes (or click "Generate release notes"!).
