A simple google brings up...

There are probably a lot more things, the Framework is massive so changes which are interesting for person x might not be as important for person y.

Uh, where to start. Here is what I love:

  • all new things about parallel computing
  • "dynamic" keyword and Dynamic Language Routine
  • code contracts
  • new background garbage collector
  • compiling only necessary parts of Primary Interop Assemblies into your application, and compatibility/versioning improvements that this infrastructure allows for pure .NET code
  • new stuff about exception handling (look for corrupted state exceptions)
  • small stuff like BigInteger and SortedSet classes
  • memory-mapped files handling in managed code

and may others, look around on the net, there is a lot of information already.

I hope I'm not incorrectly reading jignesh's question, but I would have to assume that the linking of a ton of "What's New" pages is probably not what they wanted. I would think that they could have done a search and pulled up that much.

I think what they are looking for is more of a feel for what people can break down for them as a reason to or not to go with a particular version - personal experience, not press releases.

For me, I'd say the biggest things for me that make 2010/4.0 worth the trip are the changes that allow me to distribute a client application without needing the dnFx installed on a machine, the new GC, the crazy-cool "dynamic", and (sadly, yes) the multi-monitor support.
