IME, there was a big jump in application performance from 1.3 to 1.4, 
and a smaller one from 1.4 to 1.5.  That may well have been due to the 
improvements in the JIT compiler, though.  The addition of generics in 
1.5 was an important improvement in making reliable code the first time 
around, too.

There were also significant enhancements in the language to make certain 
operations a lot easier from 1.3 to 1.4, and again a smaller jump from 
1.4 to 1.5.  I can't come up with any specific examples right now, but I 
certainly remember thinking how nice it was when I upgraded my app and 
was able to replace large chunks of hand-written code with one or a few 
lines of new method calls.
