Hey everyone! 
This beta update expands ServerQuery access and monitoring with new guest access options for SSH and Web Query, along with additional Web Query API key configuration for ownership, server assignment, and expiration.
We’ve also added a native Prometheus metrics endpoint, allowing detailed server monitoring without requiring a ServerQuery admin key, alongside optional per-packet voice diagnostics.
A big focus of this release has been server performance under heavier load. We’ve reworked internal timers, improved thread management for different packet types, and reduced lock contention throughout the server. These changes now allow the TeamSpeak 6 Server to handle around 2,000 concurrent users smoothly, compared to the recommended maximum of 1,000 concurrent users for the TeamSpeak 3 Server.
In our current local testing, we’re already running scenarios with up to 3,000 concurrent clients while maintaining similarly low server resource usage. We will continue working on further improving scalability, stability, and overall server performance throughout the TS6 Server Beta.
Additionally, this release fixes issues involving predefined Web Query API keys and a snapshot deployment hang when using -keepfiles.
We know many of you are also waiting for more news on server-side screensharing. We’ll be sharing more details and insights soon. Thank you for your patience :) <3
The default license has also been updated; the new expiration date is December 1st, 2026.
