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