ASP.NET MVC 2: Breaking changes

Question

What will be broken after migrate to MVC 2?

I wonder what breaking changes will come with MVC 2, so how traumatic will be the migration?

How much smooth have been your experience migrating?

I had no problem upgrading, just some issue with registering Castle Windsor IoC container... only had to change the signature though:
