+    The v2 volume API has been deprecated since Pike release.
+    Volume v3 API is current and Tempest volume tests can
+    be run against v2 or v3 API based on config option
+    ``CONF.volume.catalog_type``. If catalog_type is ``volumev2``, then
+    all the volume tests will run against v2 API. If catalog_type is
+    ``volumev3`` which is default in Tempest, then all the volume
+    tests will run against v3 API.

+
+    Tempest deprecate the above two config options in Rocky release
+    and will be removed in future. Alternatively ``CONF.volume.catalog_type``
+    can be used to run the Tempest against volume v2 or v3 API.

+    After this release, Tempest will support below OpenStack Releases:
+
+      * Rocky
+      * Queens
+      * Pike
+      * Ocata
+
+    Current development of Tempest is for OpenStack Stein development

+    the Stein cycle. However, this does not necessarily mean that using
+    Tempest as of this tag will work against a Stein (or future release)
+    cloud.
+    To be on safe side, use this tag to test the OpenStack Rocky release.
