AirFiber 1.1.2 has been officially released and is available for download. It addresses a single issue when compared with v1.1.1: Better 1000BaseT negotiation with certain Cisco Catalyst switches. It is identical to the 1.1.2-rc1 code. If you don't an issue negotiating 1000BaseT with a Cisco Catalyst switch, there is no reason to upgrade.
