I guess the way I should have asked is "has Disney stopped the books from continuing the story from the Crucible & Fate of the Jedi series" .
Yes, and none of that is canon anymore.
Canon as it currently stands is:
- The Movies (Episodes I-VI, the sequel trilogy, the upcoming standalone movies, and the 2008 The Clone Wars movie)
- The Clone Wars (2008 series, including the four "animatic" episodes that were unfinished; the 2003 series is no longer canon)
- Darth Maul: Son of Dathomir (Limited comic series)
- Rebels (TV series & pre-series shorts)
- A New Dawn (novel)
- Tarkin (novel)
- Ezra's Gamble (junior novel)
- Servants of the Empire: Edge of the Galaxy (junior novel)
- "One Thousand Levels Down" (short story)
- "Blade Squadron" (short story)
- "The End of History" (short story)
And everything from here on out will be canon, EXCEPT FOR future expansions to The Old Republic.
Upcoming canon material:
- Star Wars (ongoing Marvel comic; starts this month)
- Untitled Rebels junior graphic novel (February)
- Darth Vader (ongoing Marvel comic; starts in February)
- Servants of the Empire: Rebel in the Ranks (junior novel; March)
- Princess Leia (ongoing Marvel comic; starts in March)
- Kanan (ongoing Marvel comic; starts in April)
- Heir to the Jedi (novel; March)
- Lords of the Sith (novel; April)
- Dark Disciple (novel based on unproduced The Clone Wars material; July)
- Battlefront (video game; late 2015)
And probably some more Rebels-era junior and young adult novels.
I WOULD LIKE TO POINT OUT that the decanonization of everything else doesn't mean that it's completely wiped from continuity - though it seems likely that this is exactly the case for post-ROTJ stuff. But for prequel-era or earlier stuff, or even some post-ROTJ material, the writers are free to incorporate characters and events from the old EU, bringing them stories into the new canon.
The best example of this is Darth Bane - while the trilogy of books about him and his creation of the Rule of Two is no longer canon, his spirit (or something) appeared in an episode of The Clone Wars and mentioned the creation of the Rule of Two, so at least some of the Darth Bane Trilogy happened in the new canon. But the writers are free to change stuff this way - events may no longer have unfolded exactly how they did in the no-longer-canon novels, but that doesn't mean the stories full-stop never happened.
Hope this helped!
