 - The global ``md5`` implementation is removed. It was deprecated since Nextcloud 20 and not used by Nextcloud anymore.
   If you still need a ``md5`` implementation you can just use some external package like `crypto-browserify <https://www.npmjs.com/package/crypto-browserify>`_.
 - The ``OC.SystemTags`` api was removed. If you need to get the list of system tags, check `this merge request <https://github.com/nextcloud/files_retention/pull/855>`_ for how to fetch the tags directly.
