The Majority of the changes for this release can be found in the excellent selection of KDE applications. Several applications come with new features and increased stability. If you want to see the latest improvements for KDE 4.12, we have all the exciting details.
KDE 4.12 Application Changes
4.12 brings a vast number of small application changes. Many of the KDE tools and toys have been ported to QML and Qt Quick in preparation for the switch to the new Framework 5.
Kate and KDevelop
Kate users will notice improved code completion with the latest updates. Matching for code completion will now be more accurate, and smarter. The code completion pop-up dialog is now able to better recognize abbreviations. You can now match any part of a text string rather than text only appearing at the beginning of an argument. This means that the code completion pop-up dialog will appear even if you type the text at the end of the argument you are searching for.
Kmail Get Safer
Next in line we have a few Kmail improvements worth noting. Support for AdBlock is now included, as well as a URL extender designed to aid scam detection.
Updated Games and Educational Applications
If you are a fan of the games found in KDE, there have been some minor improvements. Mostly just small user interface tune-ups.
