## 🚀 Major Features

🎮 **New Multiplayer System Released**

We released **a new Multiplayer System** today, which culminates a long journey of upgrades that started last year. These include the [v6 release](/features/release-notes/2023/08-14-aug-update.md) that made our underlying JSON robust and efficient, and a new multiplayer written in-house, keeping the future in mind so that we aren't limited by multiplayer scale and room limits - even for the foreseeable future.
