- Change IPS loading of ipset contents to more efficient method to greatly reduce CPU usage after initial bootup and enabling of service.
- Other IDS/IPS back end improvements
- Fix ubnt-cfgd zombie process issue
- Added SNMPv3 back end
- Added lock wait to all iptables operations to avoid errors in cases where multiple operations happen simultaneously.

Upgrade WARNING:

- If you have GeoIP enabled, disable it first, then upgrade USG, then enable it again.
- The configuration has changed in a way that limited unstable controller and firmware version combinations could result in an invalid configuration on the new firmware versions.
- In that circumstance, if the upgrade is performed with GeoIP enabled, the system will have to be reset to factory defaults post-upgrade.

Downgrade WARNING:

- If you upgrade to any version supporting DPI without offload, disable offload (or enable IDS/IPS) and enable DPI, you cannot downgrade to a version that does not support DPI without offload.
- Either disable DPI, or enable hardware offload (or disable IDS/IPS), before downgrading. Otherwise you'll have to reset to factory defaults post-downgrade and adopt again.

About Access Point Firmware:

If you update the Access Point (AP) firmware, your device can benefit from changes that fix multiple issues encountered by wireless clients, correct different user interface problems, add various functionalities, and include support for newly developed protocols.

Before performing this task, we recommend that you read and understand all the installation steps, because there are many AP models and manufacturers available. Each producer strives to make the procedure as simple as possible, but there are cases when it's anything but that.

It is also advisable that you apply a new access point firmware in a steady power environment (UPS unit will satisfy this need), using an Ethernet cable rather than a wireless connection. The latter can be easily interrupted.

With this in mind, if you wish to apply this version, click the download button and install the package on your access point. Remember to check back with our website as often as possible so that you don't miss a single new release.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
