[Maas-devel] MAAS is now Python 3

[Andres Rodriguez]

Hi James,

MAAS 1.9 is the last version that will be backported to Trusty. The reason
is actually not the support for python3 but Django.

Django 1.7+ (1.8 currently in xenial), has changed migrations systems. This
means they have moved from south to a native migration system. This makes
it not backwards compatible with previous Django versions and really
difficult to support.

This also has actually made the upgrade path from Trusty to Xenial a
problem, however, we have been able to come up with a solution that will
allow us to make this upgrade without any issues.

Hope this helps clarify things, otherwise, please feel free to ping me and
we can discuss further.

Thanks.
