New Firmware Officially Posted (1.02 K-5, 1.01 K-r and 645D)

Edit: Official firmware info and installation instructions:
Pentax K 5/K r/645D Firmware Updates Officially Released - Pentax News & Rumors - PentaxForums.com

Couldn't see this posted anywhere yet:

Pentax released new firmware for K-5, K-r and 645D | Photo Rumors

Anyone know what it does?

This is a duplicate (the firmware is still unofficial). My guess is SDXC.

That doesn't cover the K-r/645d though. Although if threads already exist for those then feel free to delete this.

Pressing the "menu" button when you turn on your camera should work.

I don't understand the last part of your post. fwdc208b.bin is a K-r firmware, but increasing the buffer from 8 to 20 frames was done in the v1.01, for the K-5 (file name: fwdc209b.bin).
Maybe Randall S. is mixing those? Most likely, he is talking about the only released firmware - assuming that's the one you're referring to?
Until the official release, I doubt he could offer more info, anyway.

The announcement may be a bit difficult to read (apparently a poor Japanese to English translation), so I'll explain:

QuoteQuote:
* Compatible with SDXC memory card. (Transfer rate is not compatible with UHS speed class)
This delivers the promised SDXC support for the K-r and K-5. However, the camera cannot communicate with UHS cards (such as this Kingston card) at UHS-1 speeds, probably due to hardware limitations.

QuoteQuote:
* All ISO sensitivity setting can be used on Bulb mode.
The ISO 1600 limit on Bulb exposures is lifted, allowing all possible ISO sensitivity settings to be used in Bulb up to the camera's normal limit.

QuoteQuote:
* Improved functional sequence for Contrast AF and improved total speed until in focus.
Contrast detection AF algorithms have been improved, reducing the amount of time needed for the camera to focus in Live View.

The contrast detection AF improvement is something significant to consider. Just how much faster is it? I have yet to install the new firmware; I am waiting for the battery to fully charge.

Update: I've installed the new firmware. Live View AF is now slightly faster and feels more responsive.
