In reply to Ian Dunn:
Either UKC have already updated the article or I think you misunderstood the claim they were making. The article currently says...
> Michaela was the first—and remains the only—woman in the world to climb both 9a+ and 8B+.
Note the capital letter in that second grade. It's a Font bouldering grade.
They could perhaps have made it slightly clearer, given that the article prominently refers to a recent 8b+ sport onsight, but it doesn't seem incorrect.
