WorkSpaces Streaming Protocol (WSP) host agent versions

The WorkSpaces Streaming Protocol (WSP) host agent is a host agent that runs inside your WorkSpace. It streams the pixels of your WorkSpace to a client application and includes in-session features, such as two-way audio and video, and printing. For more information about the WorkSpaces Streaming Protocol (WSP), see Protocols for Amazon WorkSpaces.

We recommend keeping your host agent software updated with the latest version. You can manually reboot your WorkSpaces to update the WSP host agent. The WSP host agent is also updated automatically during the regular WorkSpaces default maintenance window. For more information about maintenance windows, see WorkSpace maintenance. Some of these features require the latest WorkSpaces client version. For more information about the latest client versions, see WorkSpaces Clients.

The following table describes the changes in each version of the WSP host agent.
