 #. Run ``python setup.py update_translations`` to compile new translation files

+   version. But take care that it isn't also bumping versions of dependencies
+   in ways that are risky to the release. *If* ``package-lock.json`` changes, you
+   need to commit it to git and tag it together with your release.
 #. Commit these changes.
 #. Tag the release in git: ``git tag $NEW_VERSION``.
 #. Push the tag to GitHub: ``git push --tags origin``.
