RT and IR version comparison


is there a documentation about the differences between RT (and IR
plugin) versions?

I need to report:

  1. the functions of RT 3.0.12 and 4.0.20
  2. the functions of IR plugin 1.0.5 and 3.0.2

In other words I would like to compare them in functionality and I need
the basic function list of RT and IR (what functions does this ticketing
system have).
