Hey, thanks! Full disclosure in my defense, I've read pages 1-245 and like 870 to present day. And I don't recall any formal announcement by HL regarding this new 'thing' and when and with what they're sending them out. I could be wrong since I did miss a chunk of pages but I also get their newsletters (seldom as of late too).
Glad you agree with me that you didn't see any HL announcement. I'm however not taking sides and reading herein for more information - as well as contributing as best I can.
But they are now, correct? I would consider this new if not different from the original design. It's one more piece of the device that can now, readily, be undone when it wasn't originally - or at least from my unit's perspective.
Cheers.
