AP7921B are there 2 versions?

[timwest]

We have a number of AP7921 which we believe are not longer getting firmware updates as they are based on NMC2.

We have bought replacement AP7921B, several of the new AP7921B have v7.0.6 firmware on them and the update tool refuses to update the firmware to the 2-5-2-5 firmware downloaded from the website.

Does this mean that these units are based on NMC2 and will therefore get no future firmware update?

Does this mean we can install the latest NMC2 firmware on them?

Does this mean we've bought replacement units that are the same on the currents one?
