Ender’s Game discussion

I've found a MMPB copy which has a star and the phrase, 'Author's Definitive Edition'. (ISBN 0-812-55070-6)

Does anyone know if this is merely a marketing ploy, or if there are actual textual changes (and how substantial those might be)?

It might mean that it is the book and NOT the short story. Ender's Game was originally a short story (you can read it in First Meetings in Ender's Universe).

It appears (according to other comments) that the racial slur scene has been edited out - in at least some versions. I don't know what other changes have been made.

pg 72:

“It can’t be too dangerous, or they wouldn’t give these guns to kids.”
“We’re soldiers now.”
“Shoot me in the foot.”
“No, you shoot me.”
“Let’s shoot each other.”
They did. Immediately Ender felt the leg of the suit grow stiff, immobile at the knee and ankle joints.
“You frozen?” asked Alai.
“Stiff as a board.”
“Let’s freeze a few,” Alai said. “Let’s have our first war. Us against them.”
They grinned. Then Ender said, “Better invite Bernard.”
Alai cocked an eyebrow. “Oh?”
“And Shen.”
“That little slanty-eyed butt-wiggler?”
Ender decided that Alai was joking. “Hey, we can’t all be niggers.”
Alai grinned. “My grandpa would’ve killed you for that.”
“My great great grandpa would have sold him first.”
“Let’s go get Bernard and Shen and freeze these bugger-lovers.”
In twenty minutes, everyone in the room was frozen except Ender, Bernard, Shen, and Alai. The four of them sat there whooping and laughing until Dap came in.

So my digital copy includes the scene. Foreword says this edition was released 6 years after initial release (March 1991).

I also don't know if they kept the same isbn for the different versions. I'm interested to know what changes have taken place, and how to differentiate between the versions - cover art, isbns, publication dates, etc.
