On the download page, the listed firmware that can be downloaded is:
Firmware_P1_0_0_5bt-P1_0_0_5ap
The release notes document however lists versions up to:
P1_0_0_8bt (bootloader)
P1_0_0_8ap (application)
As an aside, the listed AT command guides on the same page are older than what I got from my FAE.
