KDE Development Platform 4.13 Introduces Improved Semantic Search

The KDE Development Platform libraries are frozen and receive only bugfixes and minor improvements. The upgrade in the version number for the Development Platform is only for packaging convenience. All bug fixes and minor features developed since the release of Applications and Development Platform 4.11 have been included. The only major change in this release is the introduction of an improved Semantic Search, which brings better performance and reliability to searching on the Linux Desktop.

Development of the next generation KDE Development Platform—called KDE Frameworks 5—is in beta stage. Read this article to find out what is coming and see here for the latest announcements.

Improved Semantic Search

The major new addition to the KDE Development Platform is the next generation Semantic Search. To maintain compatibility, this is included as a new component rather than a replacement for the previous Semantic Search. Applications need to be ported to the new search component; most KDE Applications have already been ported. Downstream distributions can decide whether or not to ship the deprecated Semantic Search alongside the new version.

The improvements to search bring significant benefits in terms of faster, more relevant results, greater stability, lower resource usage and less data storage. The upgrade requires a one-time database migration that will take a few minutes of increased processing power.

Spread the Word

Non-technical contributors are an important part of KDE’s success. While proprietary software companies have huge advertising budgets for new software releases, KDE depends on people talking with other people. Even for those who are not software developers, there are many ways to support the 4.13 releases. Report bugs. Encourage others to join the KDE Community. Or support the nonprofit organization behind the KDE community.

Please spread the word on the Social Web. Submit stories to news sites, use channels like delicious, digg, reddit, and twitter. Upload screenshots of your new set-up to services like Facebook, Flickr, ipernity and Picasa, and post them to appropriate groups. Create screencasts and upload them to YouTube, Blip.tv, and Vimeo. Please tag posts and uploaded materials with "KDE". This makes them easy to find, and gives the KDE Promo Team a way to analyze coverage for the 4.13 releases.

Follow what is happening on the social web at the KDE live feed, buzz.kde.org. This site aggregates real-time activity from Twitter, YouTube, flickr, PicasaWeb, blogs, and other social networking sites.

Sweet Lord, the upgrade from the 4.12 to 4.13 breaks Akonadi again!

Bug filed, but watch out. https://bugs.kde.org/show_bug.cgi?id=331867

Yup, needs manual cleanup after upgrade (ubuntu 13.10->14.04)
At least kmail search works as (i) expected right now; thumbs up!
1) speed - all mailbox of few thousands emails indexed ~1 min, search results appear without delay
2) function wise - nice shortcuts below searchbox . waiting now for google style keywords from:, to: etc ...

Wonder how the rest of the desktop works in 4.13 but too scared to move away from ldxe

Since today this issue has been fixed: you may want to ask your distribution to provide the fix in their packages.

What's going at openSUSE? Usually they are the first updating their KDE packages. Now my Kubuntu machine has KDE 4.13 from its default repositories, but the suse one has still not get any update from the "backports" repository here:
Only the factory repo contains 4.13 packages: http://download.opensuse.org/repositories/KDE:/Distro:/Factory/openSUSE_...
Are there any packaging issues?
