Ubuntu 13.04 includes the Grizzly release of Openstack. OpenStack projects supported in 13.04 include: Nova, Glance, Swift, Keystone, Horizon, Cinder and Quantum. Ceilometer is also included in 13.04 in Ubuntu Universe.

Ubuntu 13.04 includes the 0.7 release of Python Juju (‘juju' package).
The initial release (1.10.0) of the Go rewrite of Juju (‘juju-core' package) is available in the -backports repository, this package is co-installable with the 0.7 version.
You can revert to the default (0.7) version by using the following:
$ sudo update-alternatives --set juju /usr/lib/juju-0.7/bin/juju
or to the new 1.10.0 release using:
$ sudo update-alternatives --set juju /usr/lib/juju-1.10.0/bin/juju
Please note that the 1.10.0 (Go version) release is not yet end-user feature complete compared to 0.7 -- for example, the LXC local provider is not yet implemented in 1.10.0; if you install both you will get 0.7 by default.

There is now machine formated JSON data describing all downloadable content for Ubuntu cloud images. The data format is called "simple streams", and can be found at http://cloud-images.ubuntu.com/released/streams/ . There is a sample client included in Ubuntu in the ‘simplestreams' package. The client can be used to keep cloud or local downloads in sync with what is available from Ubuntu.
