No, it's a milestone on the road to the production-ready release (that
being said, Google uses the "trunk" in production).

Mostly yes. AFAICT, the only breaking change is on the KeyEvent vs.
KeyPressEvent; otherwise it's only adding new features.
FYI, there's a step in the build process of GWT that checks they're
not breaking any public API (unless they explicitly want it). This
means that your code should compile against 2.1 without any change.
And of course, there are unit tests, which also are meant to check non-
regression (but the process isn't perfect, as it cannot automatically
test all of display/layout and event handling; some things have to be
verified manually).

Note that the Release Candidate 1 for 2.1 should be released shortly
(and 2.1 GA is still expected by the end of this month AFAIK); but if
you don't plan on using any new feature (just benefit from a faster
and better compiler, and from bug fixes), then go ahead with 2.1 M3.
