| 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. = Get Ubuntu 11.10 = == Upgrading from Ubuntu 11.04 == To upgrade from Ubuntu 11.04 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 '11.10' is available. Click Upgrade and follow the on-screen instructions. To upgrade from Ubuntu 11.04 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 == This release is for '''developers only'''.

| As with every new release, packages--applications and software of all kinds--are being updated at a rapid pace. Many of these packages came from an automatic sync from [[http://www.debian.org|Debian's]] Unstable branch, others have been explicitly pulled in for 11.10 Oneiric Ocelot. For a list of all packages being accepted for 11.10 Oneiric Ocelot, please subscribe to oneiric-changes: https://lists.ubuntu.com/mailman/listinfo/oneiric-changes Some of the key packages making their first appearance with this Alpha 1 release are: * [[http://kernel.org|Linux]] Kernel 2.6.39 * [[http://gcc.gnu.org/|gcc]] 4.6 compiler * [[http://projects.gnome.org/NetworkManager/|network-manager]] 0.9 ## * gnome-orca 3.0 === Linux kernel 2.6.39 === Alpha 1 includes the 2.6.39 kernel which is based on the latest mainline release candidate kernel at kernel milestone freeze [[http://kernel.org|kernel]]. This is an update from the v2.6.38 in Natty. === Gcc 4.6 === The default compiler in Oneiric Alpha 1 has been bumped from gcc 4.5 to gcc 4.6. === network-manager 0.9 === The network-manager API has also broken compatibility, and if you use the DBus API directly here as well, will also be another pain point. It at least provides an introspectable Version property, so you can do the right thing for both versions. == 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 == Ubuntu ARM == Due to kernel misconfiguration, omap3 images are non-functional for Alpha 1 ([[https://bugs.launchpad.net/ubuntu/+source/linux/+bug/791552|791552]]). They will return as normal for Alpha 2. === Ubuntu Netbook === unity-2d has been updated to 3.8.6 Upcoming work: With unity-2d being shipped as part of the desktop image this cycle, it is expected that the ubuntu-netbook image for ARM will be retired in favor of an ubuntu-desktop image with unity-2d as the default environment. === Ubuntu Headless === There are no significant changes. ##== Software Center == ## ##. |
As with every new release, packages--applications and software of all kinds--are being updated at a rapid pace. Many of these packages came from an automatic sync from [[http://www.debian.org|Debian]]'s unstable branch; others have been explicitly pulled in for 12.10 Quantal Quetzal. For a list of all packages being accepted for 12.10 Quantal Quetzal, please subscribe to quantal-changes: https://lists.ubuntu.com/mailman/listinfo/quantal-changes === Linux kernel 3.5 === Quantal Alpha-3 includes the [[https://launchpad.net/ubuntu/+source/linux/3.5.0-6.6|3.5.0-6.6 Ubuntu kernel]] which was based on the [[http://kernel.org/pub/linux/kernel/v3.x/linux-3.5.tar.bz2|v3.5 upstream Linux kernel]]. This is an update from the [[https://launchpad.net/ubuntu/+source/linux/3.5.0-2.2|3.5.0-2.2 Ubuntu kernel]] which shipped in the Quantal Alpha-2 release and was based on the [[http://www.kernel.org/pub/linux/kernel/v3.0/testing/linux-3.5-rc4.tar.bz2|v3.5-rc4 upstream Linux kernel]]. Other notable changes with the Quantal Alpha-3 kernel include changing the default scheduler back to Deadline for both the server and desktop, homogenization of the kernel configs for supported flavors and arch's, removal of redundant firmware files, and misc bug fixes. As with the Quantal Alpha-1 and Alpha-2 releases, the Quantal Alpha-3 kernel continues to include the transitioning of the i386 generic-pae flavor to become the generic flavor offering, collapsing of the virtual flavor back into the generic flavor, and standardizing of the entire linux-meta package. === Python 3.0 === For 12.10, we intend to ship only [[http://docs.python.org/release/3.0.1/whatsnew/3.0.html|Python 3]] with the Ubuntu desktop image, not Python 2. Alpha-3 continues this process. If you have your own programs based on Python 2, fear not! Python 2 will continue to be available (as the `python` package) for the foreseeable future. However, to best support future versions of Ubuntu you should consider porting your code to Python 3. [[Python/3]] has some advice and resources on this. == General == Until Ubuntu 11.10, the Unix group for administrators with `root` privileges through sudo had been `admin`. Starting with Ubuntu 12.04 LTS, it is now `sudo`, for compatibility with Debian and sudo itself. However, for backwards compatibility, `admin` group members are still recognized as administrators. Automatic Apport crash reporting has been enabled by default again to catch problems early on. It now [[http://www.piware.de/2011/11/apport-1-90-client-side-duplicate-checking/|checks for duplicates on the client side]], which will avoid uploading debug data and creating Launchpad bug reports unnecessarily in many cases now. == Ubuntu == Update Manager has been streamlined and renamed Software Updater. It also now checks for updates when launched. '''TODO: seb128 ''' |
| Line 108: | Line 76: |
| Most significant change is that the delta with Debian reduced in many areas. [[http://www.openstack.org/|Openstack]] components mostly at 'diablo-1' development snapshot. Orchestra elements have been been refreshed. == Ubuntu Server Cloud images == There are no significant changes. |
'''TODO: arosales, Daviey, smoser''' We are continuing to trial the removal of i386 Ubuntu Server CD image. This means that the primary supported installation method is AMD64, the 64-bit release (X86_64). However, other supported installations mechanisms for i386, such as mini.iso and netboot are still supported, which are an initial minimal download; and install directly from the network. i386 images for Alpha is also available, but is not declared as part of the Alpha 2 release. Feedback is most appreciated, if this causes issues for particular hardware. ##Unlike the Desktop flavour, we are currently targeting the 12.10 Server image to fit onto a standard cd image (703MB). However, some structural changes are expected for Alpha 2, which will allow us to re-review this sizing requirement. <-- deferred for next milestone. |

| The core Plasma workspace and related applications have been updated to the latest maintenance release (KDE SC 4.6.3/KDE PIM 4.4.11). The beta of the next major release (4.7 beta 1) is not in Oneiric yet.

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. = Known issues = As is to be expected, at this '''very early''' stage of the release process, there are some significant known bugs that users may run into with the Oneiric Alpha 1 Release.

Introduction
The Ubuntu developers are moving quickly to bring you the absolute latest and greatest software the Open Source community has to offer. The Quantal Quetzal Alpha 3 Release of Ubuntu 12.10 is a developer snapshot to give you a very early glance at the next version of Ubuntu.
Get Ubuntu 12.10
Upgrading from Ubuntu 12.04
To upgrade from Ubuntu 12.04 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 '12.10' is available. Click Upgrade and follow the on-screen instructions.
To upgrade from Ubuntu 12.04 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 will utilize GNU screen and automatically re-attach in case of e.g. dropped connection problems.
Download the Alpha 3
This release is for developers only. The Ubuntu Desktop images are now bigger than a standard CD, and you should use a USB for installation.
You can download Alpha 3 ISOs from:
http://cdimage.ubuntu.com/releases/quantal/alpha-3/ (Ubuntu Desktop and Server)

Updated Packages
As with every new release, packages--applications and software of all kinds--are being updated at a rapid pace. Many of these packages came from an automatic sync from Debian's unstable branch; others have been explicitly pulled in for 12.10 Quantal Quetzal.
For a list of all packages being accepted for 12.10 Quantal Quetzal, please subscribe to quantal-changes: https://lists.ubuntu.com/mailman/listinfo/quantal-changes
Linux kernel 3.5
Quantal Alpha-3 includes the 3.5.0-6.6 Ubuntu kernel which was based on the v3.5 upstream Linux kernel. This is an update from the 3.5.0-2.2 Ubuntu kernel which shipped in the Quantal Alpha-2 release and was based on the v3.5-rc4 upstream Linux kernel. Other notable changes with the Quantal Alpha-3 kernel include changing the default scheduler back to Deadline for both the server and desktop, homogenization of the kernel configs for supported flavors and arch's, removal of redundant firmware files, and misc bug fixes. As with the Quantal Alpha-1 and Alpha-2 releases, the Quantal Alpha-3 kernel continues to include the transitioning of the i386 generic-pae flavor to become the generic flavor offering, collapsing of the virtual flavor back into the generic flavor, and standardizing of the entire linux-meta package.
Python 3.0
For 12.10, we intend to ship only Python 3 with the Ubuntu desktop image, not Python 2. Alpha-3 continues this process.
If you have your own programs based on Python 2, fear not! Python 2 will continue to be available (as the python package) for the foreseeable future. However, to best support future versions of Ubuntu you should consider porting your code to Python 3. Python/3 has some advice and resources on this.
General
Until Ubuntu 11.10, the Unix group for administrators with root privileges through sudo had been admin. Starting with Ubuntu 12.04 LTS, it is now sudo, for compatibility with Debian and sudo itself. However, for backwards compatibility, admin group members are still recognized as administrators.
Automatic Apport crash reporting has been enabled by default again to catch problems early on. It now checks for duplicates on the client side, which will avoid uploading debug data and creating Launchpad bug reports unnecessarily in many cases now.
Ubuntu
Update Manager has been streamlined and renamed Software Updater. It also now checks for updates when launched.

Ubuntu Server

We are continuing to trial the removal of i386 Ubuntu Server CD image. This means that the primary supported installation method is AMD64, the 64-bit release (X86_64). However, other supported installations mechanisms for i386, such as mini.iso and netboot are still supported, which are an initial minimal download; and install directly from the network. i386 images for Alpha is also available, but is not declared as part of the Alpha 2 release. Feedback is most appreciated, if this causes issues for particular hardware.
