+    for security reasons to avoid logging sensitive information that are part

+    This release is to tag the Tempest for OpenStack Train release.
+    This release marks the start of Train release support in Tempest.
+    After this release, Tempest will support below OpenStack Releases:
+
+    * Train
+    * Stein
+    * Rocky
+    * Queens
+
+    Current development of Tempest is for OpenStack Ussuri development
+    cycle. Every Tempest commit is also tested against master during
+    the Ussuri cycle. However, this does not necessarily mean that using
+    Tempest as of this tag will work against a Ussuri (or future release)
+    cloud.
+    To be on safe side, use this tag to test the OpenStack Train release.
