Dear Kerv,
As one of our TeamSpeak NPL license holders we would like to inform you of a new upcoming client release, that will require you to update the TeamSpeak software version you are currently running on your server.
The new client (V3.2), is currently in Beta, and includes some great new features and functionality, including Twitch integration.
However, in order for the new client to function correctly, it must connect to a server running at least server version 3.1. This is due to the introduction of a new license system where both the client and server verify a legal license, together with providing additional support for the myTeamSpeak ID which is required for the Twitch integration.
Since this release will happen in the near future we urge you to update to the latest server version to prevent any interruption of the service you offer for your community.
