The first stable release since KDE 3.5, KDevelop 4.0 comes with lots of features already, even though some things had to be dropped compared to the 3.5 series due to time constraints. In particular we have focused on building an excellent C++ IDE instead of trying to integrate lots of languages halfheartedly. Of course it is still possible to add support for more languages to KDevelop and we are confident that it is actually easier than before: the best proof for that is the PHP plugin that is released alongside KDevelop 4.0. Lots of screenshots here!"
