Latest Firmware Version for - Netgear MR1100EUS ?

Apologies if this question has an obvious answer, but I’m struggling to find it.

I have a Netgear MR1100EUS and I’m trying to find out what the latest firmware version is for this model and region.

It currently has version 12.06.39.00 installed, which is a little odd as the Netgear website says that the latest firmware version for this model is 12.06.11.00.

In my understanding of version numbering, 12.06.39.00 should be the latest version as the patch version 39 is higher than the patch version 11? (Following the major version, minor version, and patch version numbering logic – not sure what the 00 indicates)

Thanks
