Firmware question

[Sergio M. Ammirata]

Is there anything new or fixed in secondary firmware 1.8.0 that makes it
worth the upgrade (from 1.7.4)?

Has anyone had negative experiences with 1.8.0?

Also, is primary 1.1.1 still the latest and greatest? I have seen 1.1.4 but
only in ram format.

Does anyone have a large network of APs with a particular firmware working
reliably? What firmware is best for a production environment?

Thanks,

Sergio
