Going to piggyback. When Disney got the rights and wiped out the old Expanded Universe, what was left were the original trilogy, the prequels, and the Clone Wars (the 3D one) cartoon. Everything else was decanonized.
Under Disney, there was a promise to make every story produced under their control of rights to be canon, and equally canon rather than the tiered system of the old Expanded Universe. There have already been canon conflicts, but generally speaking if it was freshly made after 2014, it is canon.
The old EU works that are being reprinted are labeled “Legends”.
