The only change is that the compiler refuses to compile underscore assignments. It seems to be problematic to throw a deprecated message, as this can happen in all kind of weird situations. So now you just get a syntax error, or in interactive mode (when loading with Monticello) a popup that gives you the possibility to fix the code. I suggest to integrate that into Pharo 1.0. Loading old code is a bit cumbersome, but I guess most people already fixed their code-base.
really in 1.0 we should pay attention because we want as few as possible of fixes in 1.0 :)
It is not a fix. It just throws an error when somebody tries to compile code with underscore assignments. I thought that this would give people some time to think about their code, but probably it is not that useful after all and we better just fix the real thing.
