- Ethernet Carrier drop now has high and low trigger points, new timers, etc.
- Various Security Updates

Known Issues:
- IMPORTANT: When updating, after pushing the upgrade button on the GUI, wait 10 seconds and then refresh your browser. This will ensure that you receive the newest GUI code after the radio reboots. Rare instances of corrupt configurations have been reported if this procedure is not followed. This issue only effects the AF11FX and is related to the GUI you are upgrading FROM. Even if you are upgrading via AC2, you should still refresh your screen when logging in for the first time to clear the browser cache.

- Spectrum Analyzer still Java based
- If your configuration has ALL three of the characteristics listed:

 1. You have inband management disabled
 2. You have a management VLAN enabled
 3. You manage a remote radio (far side of an airFiber RF link) by connecting the remote data port to the management port either directly or through a switched network

you will need to enable inband management on the remote radio BEFORE you upgrade. After the upgrade, you can then reconnect to the remote radio and disable inband management. Failure to do so will leave the remote radio unmanageable over the RF link (local access via the management port will still function normally). 

Notes:
- Recommend updating far end of link before near end
