Osprey 2.9.5 vs Osprey 2.4.0

I have been using Osprey 2.4.0 for some time and am considering updating to version 2.9.5 in the middle of an ongoing GABA project. Should I be concerned about the new version being so different that the version change might affect the results too much, or do you recommend going ahead and updating to the new version anyway before the current project is finished?
