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. Note that "Tagging" that the codebase is closed for this release on the date mentioned. The tarballs and packages are then being prepared and released approximately one week later. The KDE Release Team is acting as the coordinator for the 4.0 release.

Note the release is done in two portions: the KDE Development Platform 4.0 and the KDE Desktop 4.0. The KDE Desktop contains the complete package: all the main modules plus a release of the extragear module. The KDE Development Platform contains all the bits and pieces necessary to develop KDE4 applications. This means kdesupport, kdelibs, kdepimlibs and kdebase/runtime. Note the earlier freeze date for those modules and make sure you don't miss the deadline to get your fixes in.

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.
