KDE 4.3 RC3 Codenames "Cay" Out For Testing

KDE Community Ships Third Release Candidate of KDE 4.3 Free Desktop, Containing Many New Features and Improvements

July 22nd, 2009. The KDE Community today announced the immediate availability of KDE 4.3 RC3, a release candidate of the 3rd iteration over the KDE 4 desktop, applications and development platform.

While 4.3 already feels very stable, there still have been quite some changes to the code-base since the second release candidate. In order to have the 4.3.0 release well-tested, the release team decided to put out another release candidate and postpone the final 4.3.0 release by one week. The most notable change is probably a fix for a performance problem in Plasma, where applets would shortly freeze after being resized. This bug has been resolved by delaying the caching of rendered SVG images until after the resizing has finished.

KDE 4.3 focuses on polishing and completing the user experience by providing a modern and beautiful Free working environment.
Please make sure you report any existing issues, and in case of showstopper bugs, contact the KDE release team.

Highlights of KDE 4.3 are...

• Integration of many new technologies, such as PolicyKit and Geolocation services
• New Window animation effects, a more usable Run Command popup and many new and improved addons in Plasma
• Many bugfixes and improvements across all applications and more integration of features coming with the KDE 4 platform

The tree mode and the default icon mode in System Settings
