AFAICT the latest release of the framework implements the full 4.2 core specification. Richard Hall and/or Karl Pauls may know better. > > And how about the Compendium Specs?

We have a simple one based on Log4J (based on the one provided by the OPS4J project). The Apache Sling project has another one. > - Http Service We have two implementations. Both implement the R4.2 compendium specification but not the recently released R4.2 enterprise specification extensions.
