The KDE Community today released the Release Candidate for KDE 4.1. This release will is the last milestone towards KDE 4.1 due for final release on July 29th 2008, six months after the release of KDE 4.0.

KDE 4.1-rc1 is meant for testing the upcoming KDE 4.1 release and to filter out last-minute bugs. As such, the KDE 4.1 is frozen for commits unless the patches have been reviewed and are bugfix only. This way, regressions are kept at a bare minimum. For more information about what to expect in KDE 4.1, please refer to the announcement pages for Beta1 and Beta2.
