The docs themselves are updated (although a bit behind current changes) to what's coming in 3.x. But that's true there is no "what's new" document yet. See: http://lesscss.org/3.x/
There is a less-meta task tracking 3.x branch changes which I'm maintaining. See: less/less-meta#20
javascriptEnabled is false by default in 3.x for security reasons, meaning you can't use inline JS tags without enabling the option
Some behavior of calc() is slightly different (won't try to evaluate as Less math)
Other than that, lots new. Look at @plugin, Maps, each() and if() functions in docs. http://lesscss.org. Also new Less options like rewriteUrls and math settings.
In reality, few if any breaking changes, unless you are importing from a third-party library that uses deprecated features.

Is it safe to upgrade from 2.x to 3.x what are the breaking changes?

@matthew-dean perhaps these could go somewhere on the main less website?
