True, but they still introduce breaking changes as well. I just posted all the Java release notes in a sibling post, and could do the same for .NET and C++. Maybe the amount of breakage isn't as big as Python 2 -> 3, but it does happen.

The breaking changes really are tiny though. You can take a random Java 7 app and build/run it with Java 8 and be >99% confident that it will work, whereas with Python 2 -> 3 I'd be 99% confident it would fail (quite possibly even a syntax error).
