+Python 3.4
+----------
+
+Starting during the Liberty release development cycle work began on enabling
+Tempest to run under both Python 2.7 and Python 3.4. Tempest strives to fully
+support running with Python 3.4. A gating unit test job was added to also run
+Tempest's unit tests under Python 3.4. This means that the Tempest code at
+least imports under Python 3.4 and things that have unit test coverage will
+work on Python 3.4. However, because large parts of Tempest are self verifying
+there might be uncaught issues running on Python 3.4. So until there is a gating
+job which does a full Tempest run using Python 3.4 there isn't any guarantee
+that running Tempest under Python 3.4 is bug free.
