Emacs had many changes in the last decade, even very deep changes. What did not change is its fundamental concept, the foundation. And this is probably true for most software. They barely change on a fundamental level after a certain age, just receiving more features, sometimes remove some, or rework the look. So the question is, that is recognized as a real change? Did Chrome change? Seems overall the same to me. Did Firefox change, might depend on whom you ask. It changed it's internal with Quantum significantly, switched their extensions-system, added multiprocessing, but on surface, for the normal user, it's probably all the same.
