TL;DR; This is a pretty big update. There are potentially breaking changes (e.g. errors when calling ambiguous methods). And there are significant performance improvements when dealing with functional-style programming (lambdas, closures, etc).

Errors when calling ambiguous methods are unlikely to be a big hazard – at least we haven't found them to be. Most ambiguous calls are very unlikely to actually occur, which is why that change makes a lot of sense.

The big breaking change is the array indexing one – that will very much require adjusting multidimensional array code.
