This is still in PEP 101:

      ___ If this is a final release: Move the doc zips and tarballs to
          /srv/www.python.org/ftp/python/doc/X.Y.Z, creating the directory
          if necessary, and adapt the "current" symlink in .../doc to point to
          that directory.  Note though that if you're releasing a maintenance
          release for an older version, don't change the current link.

https://docs.python.org/3.5/archives/ will have the *continuously rebuilt* versions, so it's not the same.
