Hey, In the months since the Diablo release, we have been busy selectively back-porting bugfixes to the stable/diablo branches of Nova and Glance. Well, those fixes are now available as 2011.3.1 releases! These releases are bugfix updates to Diablo and are intended to be relatively risk free with no intentional regressions or API changes. The list of bugs fixed can be seen here: https://launchpad.net/nova/+milestone/2011.3.1 https://launchpad.net/glance/+milestone/2011.3.1 Please read (and add to!) the release notes at: http://wiki.openstack.org/ReleaseNotes/2011.3.1 Enjoy! Mark.
