I read last year that Atiyah thought he had found a proof of the odd order theorem of only 12 pages, using $K$-theory, and that people were trying to figure out if it was correct or not. But I never heard about it afterwards. Did people actually go through it? Was it correct or not?

Was Atiyah's proof of the odd order (Feit-Thompson) theorem false?
