This beta continues our networking overhaul as highlighted in the Tabletop Simulator 2.0 roadmap, bringing you the same TTS multiplayer but more stable, secure and reliable.
Public Beta (Steam)
As this is a substantial networking and engine update we are rolling it out as a public beta first to shake out any remaining issues before it goes live for everyone.
How to opt into the public beta on Steam
Open your Steam Library
Right-click Tabletop Simulator → Properties…
Go to the Betas tab
Select the public_beta branch from the dropdown
Close the window and let Steam download the update
You can switch back to the live version at any time by setting the beta dropdown back to “None”.

Highlights
New Steam Networking (Full Migration)
We've retired the legacy Steam P2P system and fully migrated to the new Steam Networking APIs across all multiplayer code paths.
What this means for you:
More reliable connections and fewer weird edge-case disconnects
Improved NAT traversal for smoother hosting/joining
More consistent latency behavior without changing how multiplayer fundamentally works
Better privacy & security: Connections are routed through Steam relays (no direct IP exposure) and all traffic is now encrypted
Engine Update to Unity 6.3.10 LTS
We recently upgraded to Unity 6.0 LTS, with this update bringing Tabletop Simulator to the latest and most modern Unity version release. This is preparation for the upcoming UX overhaul, UI Toolkit in 3D world space and all the latest features and performance improvements that Unity has to offer.
Behind-the-Scenes
Project & Infrastructure Cleanup
This update also includes a large internal cleanup pass:
Codebase cleanup & reorganization
Infrastructure upgrades, including our Perforce server
While you won’t see these changes directly in-game, they will speed up development and help us move through the roadmap quicker and more efficiently.
Scripting
MoonSharp Update
MoonSharp has been updated to a newer version with many miscellaneous fixes. It addresses json.encode\\decode issues with negative numbers and other bugs. [#968]
We've added stack traces! When Lua errors occur you should see detailed information on the functions that were in progress when the error happened.
Utility
The lua console command now prints results, no more endless lua log(...) when testing!
Hotseat Overhaul
Revamped the Hotseat mode so it should function the same as online players by using a new virtual network player system. This should fix all the misc hotseat bugs and issues, giving you a more reliable way to test your mods or play locally, and now remembers last tool selected for each hotseat player.
