2023.1.9f1 Release Notes

API Changes

  • Build Pipeline: Added: Build Pipeline: Added "Dedicated Server optimizations" option that strips all shaders from Dedicated Server builds.

  • SRP Core: Added: Added callbacks when RenderPipeline is created or disposed. (UUM-20646)


  • Animation: Fixed memory leak in asset import process. (UUM-33327)

  • Build Pipeline: Fixed incorrect AssetBundle dependencies are generated. (UUM-43175)

  • Core: Fixed wizard asking to upgrade when not required.

  • Core: ForEach jobs no longer allocate internal data using the TempJob allocator, eliminating one source of 'possible leak' warnings for long-running jobs. (UUM-45532)

  • DX12: Fixed sub meshes not being visible sometimes in ray tracing effects on AMD GPUs. (UUM-44073)

  • Editor: Calculate Mask value fix for last layer selection in RenderingLayerMask. (UUM-29344)

  • Editor: Clicking a foldout with Alt held will now set all child foldouts to the same expanded state when they are bound to SerializedProperty.isExpanded. (UUM-36151)

  • Editor: Ensured ExecuteInEditMode warning when entering playmode will fit in a dialog box. (UUM-44500)

  • Editor: Fixed an issue when using -nographics command line switch in MacOS editor, causing asset importer process to not work properly. (UUM-44347)

  • Editor: Fixed an issue where it was not possible to bind a shortcut to Mouse0 in the Shortcut Manager Window. (UUM-43118)
