Schedules/KDE4/4.0 Release Schedule
All dates given here are subject to revision, but we will try our best to stick to them if possible. The KDE Release Team is acting as the coordinator for the 4.0 release.
KDE 4.0
August 2006: Technical Preview 1
The first technical preview, a developer release.
November 2006: Technical Preview 2
The second technical preview, a developer release.
February 2007: Technical Preview 3
The third technical preview, a developer release.
The kdelibs API will remain as stable as possible after that, so that application developers (in particular those not having their code in the KDE SVN) can start porting towards a stable kdelibs API.
Of course the applications in the KDE SVN will have been ported all along, and it will possible to alpha-test them at this stage.
Milestones
Milestones help guide us toward a final release, and the dates are subject to change. For more details see our roadmap.
