Version 205.0 Release Notes

Breaking Changes

  • Cowatching is no longer supported: As of v205 the Cowatching APIs are deprecated; calls now no-op and log a deprecation message. (The APIs were removed from the public headers in v85; v205 disables the remaining implementation.)

    • What's Fixed

  • Fixed a Challenges.GetList() JSON serialization error: Unity C# Optional<Time> codegen no longer corrupts unset challenge start_date/end_date.
  • Fixed the abuse-report flow result callback not being delivered to the app.
  • Fixed the Unity Welcome/NUX window not auto-appearing on editor launch.

    • Improvements

  • Fixes for stability, including handling of malformed parcel data in Rich Presence and platform-context updates on Android.

    • Known Issues

    Unity Plugin Rift/PCVR app

  • The Meta Horizon Link app LIVE channel is currently incompatible with the Meta XR Platform SDK v205 Unity plugin.
  • If you are updating a published Rift/PCVR app we suggest you stay on Meta XR Platform SDK v201 Unity plugin.
  • If you still want to update your published Rift/PCVR app with the Meta XR Platform SDK v205 Unity plugin you will need to inform your user base that they will need to switch to the Meta Horizon Link app PublicTest channel.
  • Even with switching to the Meta Horizon Link app PublicTest channel, a Rift/PCVR app built with the Meta XR Platform SDK v205 Unity plugin will not have access to the Group Presence API in the Platform SDK.

    • This means the following will not function:
  • Inviting other players through the in-app methods.
  • Setting destinations and making them joinable.
  • Rejoining other players.

    • Unity Plugin Play In Editor

  • The Meta Horizon Link app LIVE channel is incompatible with the Meta XR Platform SDK v205 Unity plugin.
  • The user should receive an error in the Unity console urging them to switch to the Meta Horizon Link app PublicTest channel in order to continue using the Meta XR Platform SDK v205 Unity Plugin.
  • Even with switching to the Meta Horizon Link app PublicTest channel and using Unity's Play In Editor, the Meta XR Platform SDK v203 Unity plugin will not have access to the Group Presence API in the Platform SDK.

    • This means the following will not function in Unity Play In Editor:
  • Inviting other players through the in-app methods.
  • Setting destinations and making them joinable.
  • Rejoining other players.
