Description of problem: can openscenegraph be upgraded to 2.4 which was released in april this year please? Version-Release number of selected component (if applicable): 2.2.0
No. OSG-2.4 was released too late for inclusion in FC9, but already is part of FC10. Unfortunately OSG-2.4 is incompatible to OSG-2.3, such that upgrading FC9 to OSG-2.4 at this point in time would break the distribution.
