precision are essential for starting points." - Percival Lowell
The Ubuntu team is very pleased to announce the release of Ubuntu 12.04 LTS (Long-Term Support) for Desktop, Server, Cloud, and Core products.
Codenamed "Precise Pangolin", 12.04 continues Ubuntu's proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution. The team has been hard at work through this cycle, introducing a few new features and improving quality control.
To be a bit more precise about what we're releasing today...There are 54 product images and 2 cloud images being shipped with this 12.04 LTS release, with translations available in 41 languages. The Ubuntu project's 12.04 archive currently has 39,226 binary packages in it, built from 19,179 source packages, so lots of good starting points for your imagination!
For PC users, Ubuntu 12.04 supports laptops, desktops, and netbooks with a unified look and feel based on an updated version of the desktop shell called "Unity", which introduces "Head-Up Display" search capabilities. Finding and installing software using the Ubuntu Software Centre is now easier thanks to improvements in speed, search and usability.
Ubuntu Server 12.04 has made it much easier to provision, deploy, host, manage, and orchestrate enterprise data centre infrastructure services with the introduction of new technologies such as "Metal as a Service" (MAAS), the Juju Charm Store, and the latest OpenStack version, codenamed Essex. These technologies further position Ubuntu Server as the best OS for scale-out computing.

Long term support maintenance updates will be provided for Ubuntu 12.04 for five years, through April 2017. For those working on the ARM architecture, an 18 month supported release is also provided for the ARM server using the ARM Hard Float (HF) architecture.
Thanks to the efforts of the global translation community, Ubuntu is now available in 41 languages. For a list of available languages and detailed translation statistics for these and other languages, see:
The newest Kubuntu 12.04 (LTS), Edubuntu 12.04 (LTS), Xubuntu 12.04 (LTS), Mythbuntu 12.04, Lubuntu 12.04 and Ubuntu Studio 12.04 are also being

The i386 images use a non-PAE kernel. The non-PAE kernel will not be available in future Xubuntu releases.
Some default shortcuts have been changed, added and deleted. See New default shortcut keys for the complete list.
Pavucontrol is used instead of xfce4-mixer due to latter not supporting Pulseaudio
The Alacarte menu editor is installed by default and will work with Xfce-related menu items as well
Lots of appearance improvements, including new branding, fixes for Greybird, Ubiquity, Plymouth, LightDM and Terminal theming
Syncs, updates and patches from Debian and upstream, including xfce4-power-manager, Ristretto and gmusicbrowser
xfdesktop4 updated to support single-click opening and thumbnail support for the desktop
xfce4-settings has been updated to include the new mouse and touchpad dialog

Mythbuntu (Xubuntu + MythTV preinstalled)
Easy to install MythTV liveCD
Mythbuntu is a community supported add-on for Ubuntu focused upon setting up a standalone MythTV based PVR system. It can be used to prepare a standalone system or for integration with an existing MythTV network. Unlike similar projects, Mythbuntu keeps close ties with Ubuntu and all development is given back to Ubuntu. This architecture allows simple conversions from a standard desktop to a Mythbuntu machine and vice versa.
Mythbuntu distro ISO's to be LTS only moving forward
Mythbuntu 12.04 downloads
Ubuntu Studio is the Ubuntu flavour designed for content creation. It's produced as a DVD image that can also be converted to an USB stick and includes support for most languages by default. Ubuntu Studio 12.04 LTS is a 3 year long-term support release and will be supported until April 2015. New features include: live DVD; GUI-based installation; low-latency kernel installed by default; i386 images use the low-latency PAE kernel; Xfce as the default desktop environment; Pulse Audio with JACK bridging enabled by default; new theme, icons and default font.

Commentary on the Unity/Gnome3 desktop UI Controversy
If you've been using the Gnome 2.x desktop up to now (used by default in many common distros prior to mid 2011), I highly recommend switching to the XFCE desktop, used by Xubuntu , Mythbuntu , and now Ubuntu Studio distros. XFCE is built from the same GTK GUI "widget" libraries as Gnome and Lubuntu, so app compatibility and functionality is not an issue. Gnome/XFCE/LXDE are essentially a compatible "family" of desktops due to GTK and associated library commonalities, from most resource intensive to least.
Xubuntu is simply Ubuntu with the Unity desktop and underlying Gnome3 infrastructure replaced by the XFCE desktop. The kernel (low level OS), drivers and app compatibility (.deb software package installers, repositories, UbuntuSoftware Center "App Store" ) are the same, as well as systray apps, annunciators and tweaks similarities to Gnome 2.x.
Later this year (probably Fall timeframe), as Gnome3 and Unity mature, stabilize (debugged) and add more plugins/tweaks, I may play with them to determine their media PC/HTPC suitability for my purposes. Gnome3/Unity may be options for Moms/WAF/noobs and a 10' UI, but time will tell. I may experiment with them on my own (non-technical) family members before I use them on a "production" HTPC.
Just as other distros like Fedora, OpenSuse, Mint and others package their releases with each desktop (Gnome3, KDE4, XFCE, and maybe LXDE and others), so does Ubuntu. The only difference is that the Ubuntu variants give themselves new names Xubuntu, Lubuntu, Kubuntu, etc, whereas the others just keep the same name and call them "XFCE edition", KDE edition", etc. Another difference may be the level of support the distro provider lends the other desktop variants in terms of financial and infrastructure resources.
I may be nitpicking, but issues like this confuse non-technical users, noobs, and affect branding, an important aspect of marketing. IMO, all Ubuntu variants should be branded "Ubuntu" and just call themselves "Ubuntu- XFCE Edition", "KDE Edition", etc. Canonical should be enforcing GUI layout and style/theme conventions across Unity/XFCE/KDE/LXDE editions to reinforce the brand- simple things like using the orange circular Ubuntu logo for the "main"/"start" menu in all editions, and similar layout/design cues to unify all the desktop editions, similar to how Mint's desktops are laid out among its Mate/KDE/XFCE/Mate/Cinnamon editions. If the variant doesn't comply, it doesn't get the "Ubuntu" branding. Driver/app/repository/packaging compatibilty are bare minimums across desktop editions, of course.
My $0.02 anyways.
