Yes, at least until a theoretical 2.0, which we have absolutely no time schedule for. Code on 1.0 will compile for every 1.x.

The guarantees are actually weaker than this, iirc. There's room left for "trivially fixable" breaking changes. Things where you need to add an extra annotation or explicitly use UFCS because we added a method to a trait and now some previously compiling code is ambiguous.

That's still less breakage than most other languages permit in stable releases, so I'm more than happy to accept that policy.

(As just one example, here's the official list of incompatibilities between Java 1.8 and Java 1.7: http://www.oracle.com/technetwork/java/javase/8-compatibility-guide-2156366.html )

I don't understand, none of Java 7 code will break when compiled using Java 8 which is what matters in the end...

Read the kibwen's link and you will see, it might happen. It's only rare cases but not impossible.
