Are all the records up to date?

I mean, are all n records up to date and still relevant?

I think so! Which records do you mean exactly?

I think all the known length-872 superpermutations for n=6 are in these three files: 1 2 3.

PS. The new length-872 superpermutations for n=6 that were discovered recently are in this file: 4.
