+Subject: UnitTest cannot be run at all without CCM
+MIME-Version: 1.0
+Content-Type: text/plain; charset="utf-8"
+Content-Transfer-Encoding: 8bit
+
+Because this third party module is imported from __init__ files breaking
+nose while analysing available test (so --ignore-file cannot help)
+
+python-cassandra-driver (3.20.2-1) unstable; urgency=medium
+
+  [ Ondřej Nový ]
+  * Bump Standards-Version to 4.4.1.
+
+  [ Adam Cecile ]
+  * New upstream release 3.20.2.
+  * Add python3-mock dependency now required for unit tests.
