Main differences between 1.0.4 and upcoming 2.0?



looking over the various docs, i can’t seem to be able to
find one that explicitely lists the changes that will be
available in 2.0

i am looking at setting up RT to replace a home grown system
we currently use, and wonder whether the latest release would
be good enough, or if i should venture with the alpha (even
if this means having to delay things a little on my side).

i’d certainly appreciate if someone could detail what’s
really new in 2.0 !
