Lucasfilm formalized its definition of the Star Wars canon in April 2014, officially excluding anything made before that point beyond the original six movies and Star Wars: The Clone Wars animated series.

All ancillary projects produced since then and not marked with the Star Wars Legends banner — i.e., Del Rey's prose novels, Marvel's new line of comic books and the Disney XD animated series Star Wars: Rebels — have been counted as canonical. (You can see why Kasdan might be confused.)

Kasdan shouldn't be too worried, however; not only does The Force Awakens set the tone for the Star Wars mythology moving forward, but his next — and, he's said, final — Star Wars project is a flashback story set in the past of Harrison Ford's Han Solo.

Of course, he'll have to deal with the fact that Han Solo was apparently married when he was younger, according to the now-canonical comic books ...
