Longformer model files

I noticed this page which has base longformer files https://ai2-s2-research.s3-us-west-2.amazonaws.com/longformer/longformer-encdec-base-16384.tar.gz. These seem to be a bit old.

I also noticed that the longformer files are available at this page too and they could be the latest ones.

As of now through my organization I have access to only the first set of files. Is unzipped version of longformer-encdec-base-16384.tar.gz files from the first link the same/similar as recent files (the link just before this text)? Can I use them instead of the files from the second link? Do I have to make any changes to my code to use those files?
