+* Enhancement - User Deprovisioning for the OCS API: [#1962](https://github.com/owncloud/ocis/pull/1962)
+
+   Use the CS3 API and Reva to deprovision users completely.
+
+   Two new environment variables introduced: ``` OCS_IDM_ADDRESS OCS_STORAGE_USERS_DRIVER
+   ```
+
+   `OCS_IDM_ADDRESS` is also an alias for `OCIS_URL`; allows the OCS service to mint jwt tokens
+   for the authenticated user that will be read by the reva authentication middleware.
+
+   `OCS_STORAGE_USERS_DRIVER` determines how a user is deprovisioned. This kind of behavior is
+   needed since every storage driver deals with deleting differently.
