According to The Hollywood Reporter, a deleted line in Return of the Jedi redeems Obi-Wan Kenobi and makes him seem like less of a jerk for not telling Luke Skywalker that Princess Leia was his sister. 

The deleted scene comes from a fan project to put the special features from an out-of-print LaserDisc version of the film online. While dying, Yoda tells Luke that "Obi-Wan would have told you [about the true fate of Anakin Skywalker] long ago, had I let him."

The line not only makes Kenobi look a little better, but it changes what previously seemed to be a 100% positive relationship between Kenobi and Yoda. It didn't make the cut, which means it's probably non-canon now.
