Groovy 3.0 Released

Congrats to the team - it's been a huge undertaking and a long time and many fundamental improvements to the language are included, including a lot of harmonisations to make Groovy syntax compatible with more recent features of Java.

Does anyone know if there are any known breaking changes? I know they wrote a new parser which is the reason for the 3.0, but I can't find any place that lists out what's known to be breaking.
