[Sean Dague]

django 1.5 shipped today... yay!

it breaks horizon as setup by devstack horribly... boo!

Horizon is fixed to pin the version to django 1.4

Commit: https://github.com/openstack/horizon/commit/0d53dc7063003fa7f02c030fd1631e0cd553d22a#tools/pip-requires

[Gabriel Hurley (gabriel-hurley)]

This was fixed by pinning the django version to 1.4. We'll make 1.5 compatibility a priority in Havana.
