funny that you mention that,i was in the process of doing the @hedgedoc@fosstodon.org upgrade.
i must have change the package.json and the yarn.lock to do the upgrade.
diff-match was pinned on a specific github commit and i was not able ti detch it (i replace i with a npm dependency).
i have still to fix the saml config (as specified in the release notes).
kudos to the #hedgedoc team for their works.
