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. See the KDE Components Definition for details what SVN modules the two portions include. Note the earlier freeze date for the platform and make sure you don't miss the deadline to get your fixes in.

Milestones help guide us toward a final release, and the dates are subject to change. For more details see our roadmap.

All deadlines are due 23:59 in your local timezone.

If in doubt about any milestones please ask the release team or your module maintainer.
