- Other IDS/IPS back end improvements
- Fix ubnt-cfgd zombie process issue

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 Switch Firmware:

Given the large variety of models and different methods for upgrading the switch, if you wish to apply this package, we recommend that you read and understand the installation steps before you install a new firmware, even if you are a power user.

Usually the update procedure isn't much of a hassle as manufacturers try to make it as simple as possible; however, there are cases that are exceptions to this rule. First off, go to the system information page of the switch to check that the currently installed version isn't either newer or matching this release.

Applying a new firmware can decrease the security vulnerabilities, enhance overall performance and compatibility, improve various power management functions, resolve different errors, and add support for newly developed technologies and protocols.

It is recommended that you perform this step in a steady power environment such as the one ensured by a UPS unit, and that you don't interrupt the upgrade in any way, because this might cause the switch to malfunction.

That being said, click the download button, get and apply the new version, and check back with our website constantly to stay up to speed with the latest releases.

  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.
