The Highlights

Finishing touches 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.

Polishing up 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.

New Features 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.

Moving forward 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.

See the great GNOME3 in 30 seconds videos on youtube.

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.

Virtualization 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.

Databases 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.

Cloud 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.
