Well, I did, but I was allowing it because it was a special case. Both versions are still preserved somewhat in that the change in question, the chapter Riddle of the Past, is there in brief when Bilbo tells that version to Gandalf and the dwarves like he did before, plus LOTR covers both possibilties in saying some versions of the "Red Book" were written by Bilbo that would have his made-account, and more truthful versions were made by Frodo/Merry/Pippin that tells what REALLY happened. It was such a special circumstance that the narrative incorporated rather skillfully, but I suppose I still should have mentioned it. My bad.

Sidenote: Also there were some revisions Tolkien had made, since originally people editing the Hobbit and LOTR to against what he wrote, such as spelling dwarves dwarfs, things like that, as well as just grammatical and spelling errors, though of course there are still a few left in the latest editions.
