Ubuntu Studio Applications
This cycle we focused on developing work flows based on user tasks. This should give a more complete, functional, and robust application tool chain for users to create content. Please note that not all work flows listed in the wiki are directly supported in a default installation.

Notable applications for audio/video/graphic/photography work flows include:

JACK - lowlatency and flexible routing sound server
Ardour - multitrack digital audio workstation
qtractor - multitrack audio recorder and sequencer
LADSPA/LV2 - audio plugins
OpenShot - easy to use video editor
Blender - 3D modeler and incredible video editor/compositor
GIMP - powerful pixel-based image editor
Inkscape - scalable vector graphics editor/creator
Darktable - RAW digital photograph editor
Common desktop applications saw changes as well:

gedit - text editor
Ristretto - image viewer
Firefox - internet browser
Transmission - bittorrent client
XChat - IRC client
Audacious - audio player
Totem - movie player
Brasero - disc burner
Common Infrastructure
Up until Ubuntu 11.10, administrator access using the sudo tool was granted via the "admin" Unix group. In Ubuntu 12.04, administrator access will be granted via the "sudo" group. This makes Ubuntu more consistent with the upstream implementation and Debian. For compatibility purposes, the "admin" group will continue to provide sudo/administrator access in 12.04.
Hibernate (suspend to disk) has been disabled by default, as it was found to be unreliable, very slow and confusing to have two suspend modes. See bug 812394 for details. If you want to re-enable it, please follow this recipe.
pm-utils now has two new scripts to power down USB and various PCI devices in battery mode. A number of desktop packages were fixed to wake up less often. Both of these reduce power consumption and thus improve battery lifetime.
resolvconf is now used to manage /etc/resolv.conf on all Ubuntu systems. You can learn more here
Backports are now more easily accessible -- to enable users to more easily receive new versions of software, the Ubuntu Backports repository is now enabled by default. Packages from backports will not be installed by default — they must explicitly be selected in package management software. However, once installed, packages from backports will automatically be upgraded to newer versions.
DVD Images -- the DVD images have been cleaned up significantly reducing their size to around 1.9GB to ease consumption. The remaining software remains available via download.
