Schedules/KDE4/4.0 Release Roadmap

KDE 4.0 Release Roadmap

Milestone: Subsystem Freeze

Date: 2 April 2007


  • After this date forward, no major KDE subsystem can be committed to kdelibs.
  • The location of all classes are fixed within kdelibs.
  • Trunk is expected to contain KDE4 code only now. This effectively means that all scripts processing translations for KDE3 in trunk will cease.
  • Extragear applications that want to release based on KDE3 are expected to move to /branches/stable and work from there.
  • The buildsystem requirements are fixed; i.e, must not require a version of cmake greater than 2.4.5.
  • 31 March - 2 April is Big Changes 3-Day Weekend to make the final set of big changes.

Milestone: kdelibs Hackathon Week

Start: 15 Apr 2007 (estimated) End: 21 Apr 2007 Duration: 1 week


  • kdelibs polishing and fine-tuning.
  • Developer meeting (possible, planning TBD).
  • Full API review of Phonon and Solid (Oslo meeting)

Milestone: Alpha Release + kdelibs soft API Freeze

Date: 1 May 2007


  • Qt 4.3 is required from here until release.
  • The kdelibs API is frozen. This means that the classes and interfaces are not allowed to change, except with permission of the core developers.
  • To make an API change, post a kdelibs API exception request to the kde-core-devel mailinglist with an explanation and the code. If there are no objections after a week, the change can be committed.

NOTE: all affected modules must continue to compile and work as expected.

Milestone: Usability and Accessibility Review

Date: 8 May 2007


  • Application Usability Review
  • Application Accessibility Review
  • Continues until the start of the Beta Cycle

Milestone: Feature Freeze

Date: 1 June 2007


  • The KDE main modules are frozen for new features.
  • No new features are allowed, the focus is on stabilizing the applications and fixing all bugs.
  • The main module maintainers must indicate if they will follow the release schedule or will divert and not be released together with KDE 4.0.

Milestone: Beta Cycle, Full kdelibs API Freeze

Start: 25 June 2007 End: 24 September 2007 Duration: 3 months (estimated)


  • From this date forward, a Beta Version will be published every month until most grave bugs are resolved.
  • The kdelibs API is now frozen solid.
  • Translations are included starting with the second Beta, thus beginning a string freeze. Exceptions can be requested on the kde-i18n mailinglist.

Milestone: Release Candidate Cycle

Start: 25 September 2007 End: 22 October 2007 Duration: 4 weeks (estimated)


  • From this date forward, a Release Candidate will be released every two weeks until *all* grave bugs are resolved.
  • After the first Release Candidate there is a total release freeze. This means only regressions (breakage caused due to the KDE4 port) or grave bugs can be fixed, but nothing else.
  • With the first Release Candidate, a list of languages which will be included with the KDE 4.0 release will be made available, based on the usual rules.

Milestone: KDE 4.0 Released

Date: 23 October 2007


  • This date is based on an estimated 3 Beta's and 2 Release Candidates.
