The KDE Community and the release team have put together a release plan for the long anticipated version 4.0, which is planned to be released in October 2007. KDE 4.0 will be a major milestone for the Free Desktop, as it offers a new foundation and set of frameworks that will shape the desktop user experience for years to come.
We posted last week about the schedule, but now everything is finalized, with the freeze happening on April 1. The first beta will hit on June 25, with subsequent betas each month up until final release in October.
