+    Tempest checks a volume delete by waiting for NotFound(404) on
+    show_volume(). Sometime a volume delete fails and the volume status
+    becomes error_deleting which means the delete is failed.
+    So Tempest doesn't need to wait anymore. A new release of Tempest
+    raises an exception DeleteErrorException instead of waiting.

+    This release marks the start of support for the Pike release in Tempest.
+other:
+    - OpenStack Releases supported after this release are **Pike**, **Ocata**,
+      and **Newton**.
+
+      The release under current development of this tag is Queens, meaning
+      that every Tempest commit is also tested against master during the Queens
+      cycle. However, this does not necessarily mean that using Tempest as of
+      this tag will work against a Queens (or future release) cloud.
