Using @remix-run/changesets, there is a status command. See the docs for it in the
@remix-run/changesets readme
We have a github bot and a bitbucket addon that alert users of missing changesets.
If you want to cause a failure in CI on missing changesets (not recommended), you can run changeset status --since-master,
which will exit with a status code of 1 if there are no new changesets.
