(In other languages: cs de es fr it ja nl pt ru zh zh-tw)
As this was a shorter-than-normal release cycle, much attention went into the details so we can now give you a quality packed product. This release of world’s most powerful and flexible Linux Distribution puts the finishing touches on our boot infrastructure and package management, a bright polish to your desktop and a touch of cloud for your server.
good news – we’ve got green smoke!
openSUSE 12.3 finishes the integration of systemd and delivers a better system log experience with journald. Reliable graphical package management tools and a new theme bring a consistent experience from boot to desktop. The 1GB live images are now optimized for USB sticks and the ARM team has stable openSUSE 12.3 ARM v7 and experimental ARM 64bit images ready for this exciting architecture.
The latest desktops bring additional polish with much faster metadata handling, a new print manager and improved bluetooth integration in KDE’s Plasma Desktop and improved notifications, better file management and account integration for Exchange and Windows Live in GNOME Shell.
12.3 brings new technologies to users with the inclusion of PostgreSQL 9.2 which comes with native JSON support (noSQL style). We’ve moved over from MySQL to MariaDB as default. This is the first openSUSE release with a complete OpenStack “Folsom” for cloud fans and this release debuts the E17 desktop and the Sawfish and awesome window managers.
openSUSE moves forward with the inclusion of updated applications. DigiKam 3.0 comes with much expanded abilities for batch processing of images and new and improved filters & plugins; the major PIM applications received updates with Evolution now having an automatically updated search folder and spell checking all over while Kontact’s quick filter searches the full mail bodies and has an improved composer. Development tools like KDevelop, monodevelop and valgrind got preliminairy Android support; Development libraries like GTK3 and KDE Development Platform are included with new releases. This release also brings proper UEFI support for x86_64 hardware and experimental support for Secure Boot enabled hardware.
„We’re very proud of openSUSE 12.3 as a stable and current operating system, also we are looking forward to the openSUSE Conference in Greece this summer, where we can celebrate its release and continue working towards the future of Free Software.”
– said openSUSE Board member Richard Brown.
Plasma Desktop Widgets
KWin brings openGL in most virtual machines and per-monitor support for color management. Also introduced are better printer management with a new and smarter printer wizard and a reworked update manager Apper (0.8) which shows and describes untrusted packages and automatically downloads packages in preparation for review. See this great introduction
to Plasma Desktop on openSUSE 12.3.

XFCE, awesome, Enlightenment
Other desktop improvements include an updated XFCE which brings a tabbed Thunar file manager with improved bookmark handling and extensive performance improvements and a quake-style drop-down mode in xfce4-terminal (0.6.0) which keeps a running terminal around that can be quickly accessed through a keyboard shortcut. New in openSUSE 12.3 is awesome, a highly configurable, next generation framework window manager for X. It is very fast and extensible and primarily targeted at power users and developers. Enlightenment 17, also known simply as E, is a stacking window manager for the X Window System which can be used alone or in conjunction with a desktop environment such as GNOME or KDE.
Testing a self build OS in Studio
Virtualbox 4.2 brings support for limiting network IO bandwidth, improved 3D performance and better network device support. The KVM and Qemu updates to 1.3.0 vastly improved the USB stack with mass storage device and USB3 support as well as MSI/MSI-X support for the XHCI controller. This release includes the first major release of Boxes, an application for using remote systems and virtual machines. It offers a pretty and simple interface for handling any number of connections using Spice as protocol, featuring auto-detection of Virtual Machine format and a variety of other conveniences in a pretty interface.
12.3 moves from MySQL to MariaDB as default. MariaDB was first shipped with 11.3 back in 2010 and over the years proved itself. Native JSON support was added to PostgresSQL (9.2), it provides an efficient mechanism for creating and storing documents for web APIs. Range Types allow developers to create better calendaring, scientific, and financial applications.
12.3 is the first release of openSUSE to feature complete packages for OpenStack, the leading open source cloud computing platform. We now ship all the tools needed to setup and communicate with a cloud on your system or via an API remotely. On top of that, packages for Grizzly (next release of OpenStack due in April) are already being worked on and will be available for 12.3.
QtCreator in action
IDEs and tooling
Anjuta (3.6) with git integration improvements. QtCreator (2.6) with ‘Kits’ offering settings for which device type to develop for. KDevelop (4.4) introduces a new welcome screen which helps you to get started with a project in an intuitive way. New in 12.3 is the Fossil Distributed Version Control System, which offers a number of unique features like distributed wiki, bugzilla and blog functionality; autosync mode to reduce pointless forking and merging; and a build-in web interface.
Languages and Libraries
Mono 3 supports the new async C# 5.0. Though Python 2.7.3 remains the default, Python 3.3.0 is now available, bringing a wide range of changes. Python-qt4 supports Qt 5 now. The KDE Development Platform introduces a more comprehensive SDK for Plasma and GTK 3.6 add support for cross-fading and transitions, CSS animations and blur shadows.
KIWI (5.04.37) with support for creation of images for arm based boards, for the apt-get/dpkg package manager and btrfs seed live ISO images. The Open Build Service command line client OSC now supports creating and releasing maintenance updates for openSUSE.

The KDE and GNOME live images are now designed to be written to, booted and installed from a USB disk rather than a CD; consequently, they are now about a GB large each. They are now also more feature rich and include:
- the entire LibreOffice 3.6 stack
- the openJDK java environment
- delectable set of system recovery and backup tools, including:
- gparted, the user friendly and powerful disk partition manager
- grsync, a GUI for rsync and a very useful backup tool
- GNU dd_rescue and photorec, data recovery tools
12.3 now ships an XFCE based Live CD designed to provide a lightweight and effective environment and powerful applications for recovering lost data, backing up existing data, editing disk partitions and accessing the help channels of openSUSE. Among others, it provides the following applications:
- gparted and YaST’s disk partition manager for creating and modifying partitions
- Subset of YaST modules to help with system recovery: bootloader manager, network device management
- GNU dd_rescue and photorec for recovering lost or corrupt data
- grsync, an rsync GUI, useful for backups
- lftp: a feature rich ftp client
- a lightweight web-browser (Midori), Xchat for irc chat, and a pdf reader to read pdf manuals
SUSE Studio users

12.3 represents the combined effort of thousands of developers who participate in our distributions and projects shipped with it. The contributors, inside and outside the openSUSE Project, should be proud of this release, and they deserve a major “thank you” for all of the hard work and care that have gone into it. We hope that 12.3 is the best openSUSE release yet, and that it will help to encourage the use of Linux everywhere! We hope that you all have a lot of fun while you’re using it, and we look forward to working with you on the next release!
