I found Knopflerfish <-> OSGI version correspondence table here
KF 4.0.0 <-> OSGi R4 v4.3
KF 3.6.0 <-> OSGi R4 v4.2
KF 2.4.0 <-> OSGi R4 v4.01
KF 1.3.7 <-> OSGi R3
I would like to find the same information about Equinox but can't find it on Equinox web site.
Thanks for helping.
PS: Also pointing out Equinox implementing OSGI 4.2 would be a plus :-)
