| The Ubuntu developers are moving quickly to bring you the absolute latest and greatest software the Open Source community has to offer. The Oneiric Ocelot Alpha 1 Release of Ubuntu 11.10 is a '''developer snapshot''' to give you an early glance at the next version of Ubuntu. One of the requests received during the last Ubuntu Developer Summit was to provide a bit more information about the release process, and what's happening there. With this in mind, the release team will be adding a section about "what's happening in the background", to each of the milestones for those who are interested as part of this Technical Overview. |

| == Ubuntu Desktop Edition == === GNOME 3 has landed === [[More information on GNOME 3|http://www.gnome3.org]] * Components changes: * '''gnome-panel''' Since the 2d session on the CD in oneiric will be unity-2d we dropped some of "default ubuntu experience" patches from gnome-panel and got back closer from the upstream layout and experience. Note that currently indicators are not working because they need to be ported to GTK3 (see transitions below) * '''gnome-screensaver''' Upstream did a lot of cleaning in the screensaver code and the current version doesn't handle "hacks" (the graphics you could select to be rendered on the locked screen). We do plan to bring those back in some way this cycle, see: https://blueprints.launchpad.net/ubuntu/+spec/desktop-o-screensaver for details. The locked screen also has a gnome-shell look, we might want to look at getting it closed from the unity experience * '''gnome-keyring''' The Freedesktop Secret Service API has changed incompatibly, and the new gnome-keyring implements the new version of the API, without keeping backward compat for older incarnations of the API. If you're using the DBus API directly, this will be a pain point, especially if you need to maintain compat in the app, for older versions of Ubuntu. There also does not appear to be an introspectable way to get the API version here, which makes this that much more painful. * Transitions: * '''GTK2 to GTK3''' GNOME3 is using GTK3, we are working on migrating other softwares and wewould like to get GTK2 out of the CD for the lts next cycle. You can find documentation on how to work to GTK3 on: http://developer.gnome.org/gtk3/stable/gtk-migrating-2-to-3.html * '''gconf to gsettings (dconf)''' Gconf has been deprecated in favor of gsettings, we would like to get gconf out of the CD for the LTS as well, you can find porting documentation on: http://developer.gnome.org/gio/unstable/ch28.html * '''libpanel-applet, bonobo,gtk2 to dbus,gtk3''' The gnome-panel has been ported to use GTK3 now and dbus, the applets need to be ported to those technologies to work with the oneiric version. You can find instruction on how to port on: http://live.gnome.org/GnomeGoals/AppletsDbusMigration * '''libnotify''' The libnotify in oneiric has an abi,api break, basically upstream deprecated the possibility to position the notification next to widget or systray icons (notify_notification_(attach_to_widget|set_geometry_hints() got dropped), the Gtk``Widget argument from notify_notification_new() as well. * '''static bindings to gobject-introspection''' Static bindings (like pygtk) are deprecated in favor of gobject-introspection, see http://live.gnome.org/GObjectIntrospection for details. * '''dbus-glib to GDbus''' That one is less of a goal than other transitions listed before but if you do want to port code from dbus-glib to gdbus see http://developer.gnome.org/gio/unstable/ch29.html |

| The time around Alpha 1 is when most of the system wide changes happen for the release. Toolchain versions are one obvious case, but there are also other transitions that are happening. To give provide a bit of perspective on this, Iain Lane, one of our new release team members, has provided the following overview of what we mean when we refer to '''Transitions'''. The Ubuntu archive contains many different libraries and applications, most of which see updates from time-to-time. Sometimes these updates are incompatible with the previous version, and in these cases software which uses this old version must be updated to work with the new. Ubuntu developers usually refer to this process as transitioning. Typically transitions require touching several different packages. Changes may range from simple no-change rebuilds to porting to new API versions. The Ubuntu release team is now running a tracker at http://people.canonical.com/~ubuntu-archive/transitions/ which is being used to keep track of ongoing transitions that are taking place in the archive. The tracker has already been used in the Oneiric cycle to monitor Perl, OCaml and OpenSSL transitions. Currently we are tracking, amongst others, transitions involving Libav, Hal and GHC. If you wish to have a transition monitored by the tracker (they can be added in advance), please propose a merge against this branch: https://code.launchpad.net/~ubuntu-transition-trackers/+junk/transition-tracker following the brief documentation at http://people.canonical.com/~ubuntu-archive/transitions/readme.txt Help with completing existing transitions is welcome; please visit #ubuntu-devel on irc.freenode.net to get involved. |

Introduction
The Ubuntu developers are moving quickly to bring you the absolute latest and greatest software the Open Source community has to offer. The Precise Pangolin Alpha 1 Release of Ubuntu 12.04 is a developer snapshot to give you a very early glance at the next version of Ubuntu.
Get Ubuntu 12.04
Upgrading from Ubuntu 11.10
To upgrade from Ubuntu 11.10 on a desktop system, press Alt+F2 and type in "update-manager -d" (without the quotes) into the command box. Update Manager should open up and tell you: New distribution release '12.04' is available. Click Upgrade and follow the on-screen instructions.
To upgrade from Ubuntu 11.10 on a server system: install the update-manager-core package if it is not already installed; launch the upgrade tool with the command sudo do-release-upgrade -d; and follow the on-screen instructions. Note that the server upgrade is now more robust and will utilize GNU screen and automatically re-attach in case of e.g. dropped connection problems.
Download the Alpha 1
