Asking this question without disqualifying the answer "No breaking changes whatsoever" usually just generates a bunch of different ways of phrasing that.

- dbcurtis 10y agoNo, I don't buy that. IBM successfully transitioned a huge customer base from 709/7090 36-bit words to System 360 32 bit words. The transition from 32 to 64 bit addresses was rocky for a lot of architectures. DEC Alpha, Intel Itanium. But are you still running a 32 bit OS? K&R C no longer compiles. Not that the C to C++14 transition is what I would call an example of greatness, but it is somewhere along the success spectrum. Seriously, you will someday need to transition your customer base. How do you plan to do it?
- chc 10y agoYes, I agree with you. That's why I said you should disqualify that answer. It's by far the most common answer, but it's also obviously not the right answer.
