Today, the KDevelop team is proud to announce the final release of KDevelop 4.7.0. It is, again, a huge step forwards compared to the last release in terms of stability, performance and polishedness. This release is special, as it marks the end of the KDE4 era for us. As such, KDevelop 4.7.0 comes with a long-term stability guarantee.
