I just received a new Propeller Project Board ,(they are back in stock), and noticed it was a Rev B. My other previous purchases were Rev A. I believe I found three changes to the new revision.
1. The addition of pads for a LDO Regulator.
2. A new part number and footprint for the Micro SD Card.
3. The 6-pin Bridge is expanded to an 8-pin Bridge, and is connected to the new LDO output pad.
The Part number for the new Micro SD card holder does not show up at the store yet, but I'm sure Parallax is working on it.
Back of Rev A

In the meantime, the MPN is: DM3D-SF.
Thanks Guys and Gals! Pretty quick response from upper echelon!

Thanks for all the updates on Rev.B I sent some Engineering Requests to you in late January, and most of them were included in rev.B Nice going - rev.B makes my projects all that much better!
Why did you go with the DM3D instead of the DM3A (the push/push with springs)? I'm just curious because that's the part that I have selected for a project of mine.
It just came down to what we already had. We were using the DM3D in another product already so, instead of carrying another part type we stuck with that part.
The part should be available online today.

Quick response from Parallax, as always.
EDIT: Looks like Emily and I were typing at the same time.
