+* Enhancement - Enable group sharing and add config for sharing SQL driver: [#1626](https://github.com/owncloud/ocis/pull/1626)
+
+   This PR adds config to support sharing with groups. It also introduces a breaking change for the
+   CS3APIs definitions since grantees can now refer to both users as well as groups. Since we store
+   the grantee information in a json file, `/var/tmp/ocis/storage/shares.json`, its previous
+   version needs to be removed as we won't be able to unmarshal data corresponding to the previous
+   definitions.
