Version 207.0.0.83.331 Release Notes

New Features
Added account sign-in across the simulator, so apps that require an authenticated user now behave as they do on a device instead of failing or returning stubbed data.
Introduced a shared sign-in dialog used by every app on the simulator, including the Meta Horizon Store, so users sign in once instead of multiple times.
Introduced single sign-on for both Meta accounts and Oculus accounts, enabling testing against different account types.
Added live backend support to the Platform SDK, allowing calls that make backend calls on headset to execute against the real service using the account token and return real data.
Added a control bar beneath the foreground app to issue a back action or close the app, matching the control bar behavior on Meta Horizon OS.
Added support for rendering up to 4 application panels in a layered stack for easier navigation between multiple applications.
Introduced a Window Manager overview with thumbnails of every open app, enabling users to manage apps more effectively.
Added Home and Window Manager buttons to the Settings menu for easier access.
Added a bundled set of system apps to match the app set on a device more closely.
Added support for the Layout SDK, enabling apps that open child windows from a parent window to render the layout correctly in the simulator.
