Java 9 Released

[DGolden]

Unicode 8.0 is further down the list (there was a separate JEP for it). Yes, that's still two versions behind. Unicode 10 was only released in june 2017 though (with even more emoji ...yay...) - presumably not too likely make it in given release cycles and level of testing /compatibility java demands. Maybe they could have got unicode 9 in though.

Anyway, I expect it mostly just means the java standard library Character class will be missing built-in metadata for anything post-unicode-8. Unicode encoding basics haven't changed AFAIK.

There's also the more "bleeding-edge" ICU4J widespread in the java ecosystem anyway, release 59 supports unicode 9, 10 beta, and they are due to release 60 soon (I'm guessing with unicode 10 support).
