[FIRMWARE] 3.9.42.9152 for UAP/USW has been released

[UniFi]

We've prepared firmware 3.9.42.9152. Please see below for the changelog and links to the firmware binaries. This is a stable candidate release which is currently available via the blog only.


Firmware changes since 3.9.40:

• [nanoHD/IW-HD] Add VHT160 support for RF Environment scanning.
• [nanoHD/IW-HD] Fix hidden SSID provisioning.
• [nanoHD/IW-HD] Fix reported signal of neighboring APs (reported HERE).
• [nanoHD/IW-HD] Fix an issue with TX power provisioning.
• [nanoHD/IW-HD] Performance and stability improvements.
• [IW-HD] Fix DVLAN issue.
• [USW] Fix RADIUS server provisioning.
• [HW] Fix inform URL caching issue.
• [HW] Various bug fixes and improvements.
• [SEC] Security improvement. It's a low/medium threat which was discovered internally.

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.
