Version 4 Beta 1 of KDevelop has been
"On behalf of the KDevelop team I am happy to announce that we have reached the next milestone on our way to a final release, KDevelop 4 Beta 1. We feel that KDevelop 4, although in no way feature complete, is now usable and stable enough to get first feedback from a somewhat wider audience. Being a beta there are of course still bugs and missing functionality, but we have excellent language support for C++, integration of the CMake buildsystem, subversion, git and even starts of Qt GUI designer integration.
