[FIRMWARE] 220.127.116.1152 for UAP/USW has been released | Stable
on 07-25-201810:21 AM
We've prepared firmware 18.104.22.16852. Please see below for the changelog and links to the firmware binaries. This is a stable release which has been posted to our website, and pushed out to various recent controller branches (5.6+).
This firmware was not released as stable for all UniFi devices. If any model(s) of AP you have aren't listed, and they are on 3.9.41 or later, then you may need to run a command via shell to get that device off of its current firmware. We have a thread detailing that process HERE.

One is of medium/low severity It was privately disclosed and it requires external data otherwise it's not possible to exploit.
The other is of low/medium severity. It was discovered internally.
*Controller support may vary/ pending.
NOTE: You may start to see EVT_AP_RestartProc events in the controller log. If you see these, please report if there is anything specifically in your setup that triggers the events. The processes restarting is not new, but the reporting of the restarting is, and we are using these reports to clean up these issues.
IMPORTANT NOTE: In preparation for an upcoming code merge, we've updated the minimum firmware version to 3.9.42 for certain hardware. That means if you flash this firmware onto any HD/SHD/XG/BaseStationXG then you will not be able to downgrade to firmware prior to 3.9.42.
*This firmware is meant to be a one file solution that works with all models of UniFi switch. You can use it when upgrading from 3.9.40+ only. It will not work when upgrading from earlier releases.
Any and all feedback is welcome, including lettings us know about successful device upgrades. When reporting an issue, please ensure that you include the following information:
Firmware version (previous and current).
Links are all HTTPS. This assumes your device(s) are currently running at least 3.7.51, and that the device's date is properly set (i.e. it can reach a NTP server). If you encounter issues with the upgrade, or your device isn't on a minimum supported firmware, then you can change the link to HTTP before performing the upgrade.
