+All of the following will generate a `<major>.<minor>.<patch>-dev<build>` version:

+pipenv run bumpversion major --message 'chore: release {new_version}'
+
+# Minor
+pipenv run bumpversion minor --message 'chore: release {new_version}'
+
+# Patch
+pipenv run bumpversion patch --message 'chore: release {new_version}'
+```

+To bump up the `<build>` number, run the following:
+
+```bash
+pipenv run bumpversion build --message 'chore: release {new_version}'
+```
