Although Red Hat is no longer supporting RHEL 6 after Icehouse, a number of
users such as GoDaddy and CERN are using Software Collections to run the
Python 2.7 code.

However, since this modification would only take place when Mitaka gets
released, this would realistically give those sites a year to complete
migration to RHEL/CentOS 7 assuming they are running from one of the
community editions.

What does the 1.1.1 version bring that is the motivation for raising the
limit ?
