Sonic the Hedgehog had a slight alteration to the end credits on the Blu-ray release compared to the theatrical release.

There’s no credit for Coleen O’Shaughnessey as the voice of Tails in the mid-credits scene in the theatrical release but she is credited on the Blu-ray release.
Makes sense that they would retroactively add a credit for Tails’ voice since it’s one of the most spoiled scenes in the movie, and probably one of the most spoiled mid-credits scenes in all of modern cinema.
Added. Can you provide a source?
TV Tropes referenced it in “The Second Visitor” section of the Characters page.
And I found a Korean-sourced WEBRip that leaked before the film’s digital release and it still has the theatrical credits which doesn’t credit “The Second Visitor”.
