# Checklist for creating a new release

- [ ] Update `CHANGELOG.md` for the new version
- [ ] Change version number in `certego_saas/version.py`
- [ ] Verify CI Tests
- [ ] Merge the PR to the `main` branch. **Note:** Only use "Merge and commit" as the merge strategy and not "Squash and merge". Using "Squash and merge" makes history between branches misaligned.
- [ ] Create release for the branch `main`.
