Bug Fixes​

  • A prior release inadvertently allowed developers to bypass the minimum clipping plane in Unity. We have restored the enforcement of the minimum clipping plane to 37cm.
  • Fixed compiler errors when the package com.unity.xr.openxr is also installed.
  • Fixed MLDepthCamera errors when closing the application.
  • Improved performance of MLWebRTC.MLCameraVideoSource by making it start the video capture asynchronously.
  • Fixed enforcement of MLCamera’s near clip distance when “Fix problems on startup” is enabled.
  • Fixed occasional crash when changing scenes while MLMediaPlayer is playing local video file.
  • Addressed MLAnchors query timing to reduce likelihood of missing pose errors.
  • Fixed CV camera errors when resuming from sleep mode.
  • Fixed CV camera errors when resuming from menu.
  • Fixed MLWorldCamera Invalid Parameter error spams.
  • Renamed Tests assembly definition.
  • Fixed caching logic for CustomHapticsPatterns to avoid using incorrect cached patterns.
  • Fixed MLVoice.IntentEvent’s EventSlotsUsed list within the OnVoiceEvent so it properly lists all Slots used in the voice command.
  • Optimized MLMeshing API and components to reduce memory usage.
  • Fixed spamming errors caused by not detecting eyes in the eye tracking example.

Deprecations & Removals​

  • The MLMediaDRM API has been marked as obsolete and will be removed in a future release.
  • MLWebView.GetScrollSize() and MLWebView.GetScrollOffset() have been marked as obsolete and will be removed in a future release.

Known Issues​

  • MLWebRTC: When disconnecting from a session, the camera does not shut down cleanly if the NativeSurface buffer format was used, causing the application to hang for as much as 30 seconds.
  • WebRTC can take a very long time to connect.
  • CV camera throws errors after background/doze modes.
  • CEA608, TTML, and WebVTT video sources are not displaying any subtitle/closed caption text in the test scene for media player
