DRM 3 Catalog Not Up to Date with latest firmwares for R510

The catalog for DRM 3 doesn't have the latest firmware for the R510 or R710. Both have had new BIOSs released within the last month but the catalog DRM 3 still has 1.12/6.4 respectively.

As far as I can tell from the last updated timestamp on the full sized SUU disks they haven't been updated in some time either.

How am I supposed to update a Non-Windows system if the SUU disks either created through DRM 3 or downloaded from Dell's support pages are so out of date with the current firmware releases?
