"It's quite a big rewrite architecturally speaking. The major thing that started this off was the release of Qt4, the toolkit which KDE is based on," said Australian KDE developer Hamish Rodda. Rodda said Qt4 brings a lot of features and API improvements to version 4.0, as well as significant enhancements in the way memory is used. "So it ends up making KDE less resource intensive than KDE 3, which is quite an improvement," he said. KDE 4.0 boasts a modern architecture that Rodda says is more "future-proof" and designed to last for many years, "whereas some of our other technologies were dependent on certain programs, like the aRts program for audio which unfortunately became a bit of a burden on previous KDE releases." According to Rodda, despite not being matured just yet there are developers working on the porting of KDE 4.0 to both Mac and Windows.
