11.10 Highlights

Updates from the KDE community

Plasma and Applications 4.7

The latest stable release of KDE’s Plasma Workspaces and Applications brings new features and improvements all around. Highlights include:

• Visual updates include a new Oxygen icon theme
• A cleaner default look to Dolphin
• Gwenview’s new ability to compare two or more images
• New breadcrumb feature in the Kickoff menu that simplifies navigating submenus
• More improvements in the Network Management widget

More information on the Plasma and applications pages.

11.10 will have KDE SC version 4.7.1; Due to it’s very recent release, the latest version, 4.7.2, will be available in our updates PPA until it is available in the standard repositories.

Kontact 4.7

Kubuntu 11.10 brings you the new Kontact suite, which includes the Kmail 2. The look and feel is familiar, but under the hood, most of the applications have been updated to use the Akonadi storage service. This will enable better email, calendar, and other PIM activities moving forward.

IMPORTANT: Do note that this is a major upgrade to the mail, calendar and addressbook systems, and as such still needs usage and migration testing. While loss of data should not be an issue, it is highly recommended for current Kontact users to back up all important data, mail, contact information and calendars if you plan to upgrade to 11.10.

Our KMail2 page has more information on the migration process, the issues involved and how to import your previous data instead of migrating.

Amarok Improvements

This new and improved version of the default music player features native support for remote NFS & SMB/CIFS collections, a better looking user interface, support for gpodder.net, as well as vastly improved reliability.

For more information have a look at the release announcements of Amarok 2.4.1 and 2.4.3.

Test Drive OpenGL ES Powered Desktop Effects

For those adventurous and curious, we have packaged the work towards using the mobile friendly OpenGL ES.

To try running your system desktop effects on OpenGL ES install kde-window-manager-gles. More information can be found on Martin Gräßlin’s blog.

Low-Fat Settings

Kubuntu introduces Kubuntu-Low-Fat-Settings: a collection of configuration options that reduce memory usage and even speed up KDE’s loading time. This will help Kubuntu run better on older, lower-end systems.

Some of the many tweaks include:

• Turning off compositing by default.
• Disabling the automatic loading of various modules, such as bluedevil, the free space notifier, some Nepomuk services, and a other components.
• Reducing the number of default Krunner plugins that are loaded automatically.
• Reducing the amount of graphical effects used in the window decoration.
• Significant reductions in memory usage (up to 32%) and the subsequent savings in KDE’s loading time (up to 33%) can be had simply by installing the package kubuntu-low-fat-settings!
