Knopflerfish 3.0 is the next major version of Knopflerfish OSGi, designed to be compliant with the newly published OSGi R4 V4.2 specifications. KF3 fully implements the core and service compendium functions according to OSGi R4 v4.2. The KF3 overview page describes the development of KF3 in more detail. KF3 also includes several other improvements and fixes. The Release Notes includes the complete list of features and fixes.
With the release of KF3 the former main development branch (KF2), will enter maintenance mode. Before entering maintenance mode a KF 2.4 was built and released today. KF2.4 includes all fixes in the trunk since 2.3.3 and is probably the last minor release of KF2 (2.N.N). Maintenance releases (2.4.N) can still be expected.
