This is work in progress on Knopflerfish 2, the next major release of KF. The objective is to implement the OSGi R4 specifications fully. This includes the:

Core Specification
Service Compendium
Mobile Specification, MEG - Not released yet.

A beta-3 version has been released and is available for download.

Release Schedule

The release schedule for KF 2 is as follows:

Dec 2005, Alpha version (alpha-1 released 21 Dec 2005)
End Jan 2006, Beta version (beta-1 released 27 Jan 2006)
Beginning Feb 2006, 2nd Beta version (beta-2 released 10 Feb 2006)

Mid Apr 2006, 2.0 RC1
End Apr 2006, official 2.0 release

The official 2.0 release is now targeted at the end of April. The release date will be set as soon as the release date of the formal OSGi R4 TCK is announced.

A release candidate will be made available in the beginning of April 2006. This version can be expected to be the very close to the final 2.0 release.

The 2.0 release will not include the MEG parts due to the release schedule of the OSGi MEG specifications.

Status KF 2, KF 2.0-beta-4 release

With this fourth beta release, the KF 2 framework is feature complete in all mandatory parts. Of the optional parts only minor items remain. All other parts are implemented and fully functional.

The Service Compendium was already in the beta-1 release feature complete. Minor fixes has been added in this release.

The desktop and framework commands have been updated in a number of ways to reflect new features in K4.

The table below describes what parts have been implemented and what parts are still pending in the KF 2.0 beta 2 release.
