Several key server technologies, from MAAS to Ceph, have been updated to new upstream versions with a variety of new features.
Ubuntu 14.10 includes the OpenStack 2014.2 (Juno) release of the following projects in Ubuntu main:
OpenStack Compute -- Nova
OpenStack Identity -- Keystone
OpenStack Imaging -- Glance
OpenStack Block Storage -- Cinder
OpenStack Networking -- Neutron

WARNING: Upgrading an OpenStack deployment is a non-trivial process and care should be taken to plan and test upgrade procedures which will be specific to each OpenStack deployment.
Containers launched with libvirt-lxc can now be apparmor-protected.
Libvirt now provides cgmanager support allowing use of libvirt inside containers without cgroups mounted.
Migration of pc-1.0 VMs from a 12.04 host must be done first to a 14.04 host, to the pc-1.0-precise machine type. From there, they may be converted to a new machine type, such as pc-i440fx-trusty, and migrated to a 14.10 host.
Kvm is now supported on the ppc64le architecture.
Cgmanager now has a new compiled client tool, and supports new methods including Prune, ListTasksRecursive, and ListControllers. It now supports the features needed for systemd-shim to properly close sessions.
This includes container checkpoint and restart as a tech preview.
Cloud-init 0.7.6 brings several bug fixes along with support for booting ubuntu with systemd. Also featured is improvements when using vendor-data on OpenStack.
bcache support is now included as a technology preview, enabled in the kernel and via the userspace package bcache-tools, but without installer support. We highly recommend that you take full system backups before experimenting with it. It has been enabled with a focus on server use cases. Some desktop use cases should also work, but we have observed some issues when attempting to combine bcache use with LVM and md.
Juju, the service orchestration tool for Ubuntu, has been updated to the latest current stable release, 1.20.10. See the upstream release notes for full details of all new features and improvements in this release.
Docker 1.2 is released in Utopic. For the absolute latest upstream version of Docker.
MAAS has been updated to the latest current beta release, 1.7-beta8. Many new features have been added, and lots of bugfixes too. Full release notes will be available shortly.
