Recent BLM Mailing to Claimants Options

[swizz]

I noticed a fat envelope in my mailbox from the BLM/DOI. I immediately thought "oh boy... what now??" I figured it couldn't be too serious since it was not sent Certified Mail.
To my surprise, the the first thing I saw when I opened it was "Thank You...".
Basically a copy of my Mining Claim Filing, the new Maintenance Fee Waiver Certification (Form 3830-2), and Affidavit of Annual Assessment Work (Draft Form) - "not officially approved... but preferred" ???????

Thought I'd run these forms by the pros to see if anything significant has changed or if there's anything fishy, don't want to get unwittingly suckered into anything - "not officially approved... but preferred" kinda raises a small red flag for me. Here are some pics of the mailing. I blotched out my personal and specific claim info. Any other claim owners get this yet? Perhaps just me, since I filed this claim in 2010 and it's standard op procedure?
Thanks.
