For the records:
if a plugin is compatible with SU2014, possibly it's not compatible with any previous release due to heavy change to Ruby, which passed from 1.8 to 2.0, with many "breaking changes" which can prevent old script from working.
Same happens when passing from SU2016 to SU 2017.
This is the sequence of updates which may impact plugins compatibility:
