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.
We have fixed a lot of bugs since the last alpha release and there has been some improvements done especially for users who are new to KDevelop to lower the entrance barrier. To get a first impression you can have a look at the recent blog posts from David and myself.
For those eager to try it out, the source packages are available from the KDE mirrors. Just go to download.kde.org and choose a mirror. There are two source packages there, kdevelop and kdevplatform. KDevPlatform needs to be built before KDevelop itself and both require KDE 4.2.0. Kubuntu users can install kdevelop-kde4 from the kubuntu-experimental archive. Mandriva users can find it with the KDE 4.2 packages. openSUSE has packages in the KDE 4 Extra-Apps archive.
