+* Bugfix - Fix `OCIS_RUN_SERVICES`: [#4133](https://github.com/owncloud/ocis/pull/4133)
+
+   `OCIS_RUN_SERVICES` was introduced as successor to `OCIS_RUN_EXTENSIONS` because we
+   wanted to call oCIS "core" extensions services. We kept `OCIS_RUN_EXTENSIONS` for backwards
+   compatibility reasons.
+
+   It turned out, that setting `OCIS_RUN_SERVICES` has no effect since introduced.
+   `OCIS_RUN_EXTENSIONS`. `OCIS_RUN_EXTENSIONS` was working fine all the time.
+
+   We now fixed `OCIS_RUN_SERVICES`, so that you can use it as a equivalent replacement for
+   `OCIS_RUN_EXTENSIONS`
