I know the page is being updated with new categories, But I do want confirmation in what categories we'll see. Will their be a 1.11 and 1.2 version for each already existing category or will it just be any version as it is now? Will there also be new custom mode categories including the new monsters?

1. I don't think it is necessary to add separate categories for all versions, but I've added the "Version" attribute to differentiate runs done on 1.1.1 and 1.2, even if the changes between them may be minimal (although only the Story Mode is practically unchanged).
2. Yeah, there will be new challenges for the Custom Mode and some of them will also be updated, like the Tower Fellas. If you want to, you can also suggest your own challenges — I don't mind adding those if they look interesting.
