KDE Applications 4.11 Bring Huge Step Forward in Personal Information Management and Improvements All Over

Wednesday, 14 August 2013

The Dolphin file manager brings many small fixes and optimizations in this release. Loading large folders has been sped up and requires up to 30% less memory. Heavy disk and CPU activity is prevented by only loading previews around the visible items. There have been many more improvements: for example, many bugs that affected expanded folders in Details View were fixed, no "unknown" placeholder icons will be shown any more when entering a folder, and middle clicking an archive now opens a new tab with the archive contents, creating a more consistent experience overall.

Kontact Suite Improvements

The Kontact Suite has once again seen significant focus on stability, performance and memory usage. Importing folders, switching between maps, fetching mail, marking or moving large numbers of messages and startup time have all been improved in the last 6 months. See this blog for details. The archive functionality has seen many bug fixes and there have also been improvements in the ImportWizard, allowing importing of settings from the Trojitá mail client and better importing from various other applications.

This release also comes with some significant new features. There is a new theme editor for email headers and email images can be resized on the fly. The Send Later feature allows scheduling the sending of emails on a specific date and time, with the added possibility of repeated sending according to a specified interval. KMail Sieve filter support (an IMAP feature allowing filtering on the server) has been improved, users can generate sieve filtering scripts with an easy-to-use interface. In the security area, KMail introduces automatic 'scam detection', showing a warning when mails contain typical phishing tricks. You now receive an informative notification when new mail arrives. and last but not least, the Blogilo blog writer comes with a much-improved QtWebKit-based HTML editor.

Extended Language Support for Kate

Advanced text editor Kate introduces new plugins: Python (2 and 3), JavaScript & JQuery, Django and XML. They introduce features like static and dynamic autocompletion, syntax checkers, inserting of code snippets and the ability to automatically indent XML with a shortcut. But there is more for Python friends: a python console providing in-depth information on an opened source file. Some small UI improvements have also been done, including new passive notifications for the search functionality, optimizations to the VIM mode and new text folding functionality.

Other Application Improvements

In the area of games and education several smaller and larger new features and optimizations have arrived. Prospective touch typists might enjoy the right-to-left support in KTouch while the star-gazer's friend, KStars, now has a tool which shows interesting events coming up in your area. Math tools Rocs, Kig, Cantor and KAlgebra all got attention, supporting more backends and calculations. And the KJumpingCube game now has features larger board sizes, new skill levels, faster responses and an improved user interface.

The Kolourpaint simple painting application can deal with the WebP image format and the universal document viewer Okular has configurable review tools and introduces undo/redo support in forms and annotations. The JuK audio tagger/player supports playback and metadata editing of the new Ogg Opus audio format (however, this requires that the audio driver and TagLib also support Ogg Opus).

Installing KDE Applications

KDE software, including all its libraries and its applications, is available for free under Open Source licenses. KDE software runs on various hardware configurations and CPU architectures such as ARM and x86, operating systems and works with any kind of window manager or desktop environment. Besides Linux and other UNIX based operating systems you can find Microsoft Windows versions of most KDE applications on the KDE software on Windows site and Apple Mac OS X versions on the KDE software on Mac site. Experimental builds of KDE applications for various mobile platforms like MeeGo, MS Windows Mobile and Symbian can be found on the web but are currently unsupported. Plasma Active is a user experience for a wider spectrum of devices, such as tablet computers and other mobile hardware.

KDE software can be obtained in source and various binary formats from and can also be obtained on CD-ROM or with any of the major GNU/Linux and UNIX systems shipping today.


Some Linux/UNIX OS vendors have kindly provided binary packages of 4.11.0 for some versions of their distribution, and in other cases community volunteers have done so.

Package Locations

For a current list of available binary packages of which the KDE's Release Team has been informed, please visit the Community Wiki.

The complete source code for 4.11.0 may be freely downloaded. Instructions on compiling and installing KDE software 4.11.0 are available from the 4.11.0 Info Page.

System Requirements

In order to get the most out of these releases, we recommend to use a recent version of Qt, such as 4.8.4. This is necessary in order to assure a stable and performant experience, as some improvements made to KDE software have actually been done in the underlying Qt framework.
In order to make full use of the capabilities of KDE's software, we also recommend to use the latest graphics drivers for your system, as this can improve the user experience substantially, both in optional functionality, and in overall performance and stability.
