Upgrade from 3.2.2 to 3.4.2?

hi,
i’m using RT3.2.2 with oracle 9206 on linux. is there
a strong reason that i should upgrade to RT3.4.2?
RT3.2.2 is working fine at my site and i’m not
encountering any bugs. but if there’re significant
changes between these 2 releases then i’d consider the
upgrade. thanks
jim
