On April 25, 2014, in preparation for the upcoming feature films, Lucasfilm announced that the Expanded Universe was rebranded as Legends, thus, the term “canon” come to be reserved exclusively for George Lucas’ canon - the six movies and the seasons of Star Wars: The Clone Wars he developed and producered - and the movies, television series, novels, comics, toys and video games created by Lucasfilm after the acquisition. Since then, the only previously published material still considered canon are the six original trilogy/prequel trilogy films, novels (where they align with what is seen on screen), the Star Wars: The Clone Wars television series and film, and Part I of the short story Blade Squadron.
So, as a rule of thumb, only products coming from Lucasfilm directly are considered canon.
I remembered this because I was an active 501st member and remember the uproar when the EU was left out of the canon. A lot of people was pissed with the decision. But it is what it is.
That’s old. It all changed in 2014.

Yes… I know. I was describing how the old EU canon worked, in response to a comment about the old system.
