System updates
For added security and stability, updates for multiple third-party packages and libraries are included as part of this release.

You must upgrade to VidyoGateway version 21.2.0 from VidyoGateway version 20.1.0 or later. Therefore, if you have a VidyoGateway version earlier than 20.1.0, you must first upgrade to 20.1.0 and then upgrade to version 21.2.0. Please refer to the “Upgrade a VidyoGateway 20.1.0 Cluster to Version 21.2.0” section below for more information. These steps must be done in order.
Additionally, you can refer to the Upgrade Steps Lookup Tool article on the Vidyo Support Center for information on how to upgrade to VidyoGateway version 21.2.0 from the version you are currently running. This article lists the steps you need to take for your particular version, including which Security Updates you may or may not need to install.
If you have installed a previous VidyoGateway version 21.2.0 beta, you should first downgrade your VidyoGateway to 20.1.0 using the Recovery Utility on the System Console, and then upgrade directly to the GA 21.2.0 version. For more information, please refer to "Running the Recovery Utility" in the Performing Advanced Configuration section of the VidyoGateway Administrator Guide.

VidyoGateway version 21.2.0 is compatible with VidyoPortal version 18.4.0 and later.
