Any new version for data center design ?

Not really. It took a while for this design to be commercialized and the industry isn't ready for anything new yet. There's plenty of newer academic work like Jellyfish but I would expect Clos to reign for 10-20 more years.

So you think this is still current https://storage.googleapis.com/pub-tools-public-publication-... ?

We don't know what Google has done after that paper so they may have moved on to something else.

Outside of hyperscale datacenters you still can't even buy a fabric comparable to Jupiter/Firepath.

They have gone on an evolutionary path and this followup paper ("Jupiter Rising") summarizes the changes over the years
