6000.0.17f1 Release Notes

Improvements

• Editor: Improved Editor performance when performing drag, drop, copy, and paste operations with complex prefabs.

• Graphics: Added shader pragma disable_ray_payload_size_checks that can be used in .raytrace shaders to disable ray payload size compatibility checks between ray generation and hit shaders.

• IL2CPP: Support volatile stores using the ldind.ref opcode.

• Physics: Added a new memory root "Physics Debugger" for tracking the memory allocated by the Physics Debugger tool.

Changes

• Documentation: Renamed Game Server Hosting to Multiplay Hosting as part of rebrand.

• iOS: Use the f16 color format for the metal layer and internally by default when using "wide color" (P3 color pace).

Fixes

• 2D: Fixed an issue where Tile Palette window would not update when creating first palette or error messages would not show up on when it reached an error state. (UUM-77329)

• Android: Fixed an issue with native plugin being skipped for ARMv7 architecture if target CPU is not set. (UUM-77679)

• Android: Fixed misspelling in AndroidPluginImporterUtilities name. (UUM-77692)

• Asset Pipeline: Increased the integrity of the asset database to minimize the risk of corruping a library folder. It changes the way we flush in-memory data to the database internally.
  Unfortunately this change might introduce a performance regression for users with spinning disk hard-drives. To accommodate this user group, we are introducing the command-line flag sacrificeDBIntegrityForPerformance, which you can use to opt out of this new behaviour and fall back to the way it has worked before. (UUM-14959)

• Editor: Fixed a bug where a restart editor prompt appeared when users change the Incremental GC or Active Input Handling settings for inactive platforms or build profiles. (UUM-70192)

• Editor: Fixed a ContentFile deadlock that occurred when unloading large numbers of files simultaneously. (UUM-74146)

• Editor: Fixed a leak of Windows GDI objects when calling DisplayDialog. (UUM-76440)

• Editor: Fixed a null exception that would occur when rendering text without settings assigned. (UUM-75106)

• Editor: Fixed an assert that could spam the console in the Linux Editor while in Play mode if the cursor was locked and the mouse was moved quickly. (UUM-77694)

• Editor: Fixed an Editor crash that would occur when using deferred rendering on cameras with a target render texture that fails to create, such as due to an unsupported texture format without compatible format fallbacks enabled. Now console errors are output instead. (UUM-71811)

• Editor: Fixed an issue where errors where thrown when resizing the SceneView to 0 height or width. (UUM-76816)

• Editor: Fixed an issue where GPU Skinning options weren't being displayed on certain platforms. (UUM-76079)

• Editor: Fixed an issue where the grid was not visible in the Universal 2D Template project. (UUM-74314)

• Editor: Fixed text going out of bounds when using justified alignment. (UUM-66534)

• Editor: Fixed the location of platform build warnings in the Build Profile window. (UUM-73125)

• Editor: Restored the tooltip to the View Tool button in the Tools overlay within the Scene view. (UUM-78214)

• GI: Fixed an issue where shader variants with LIGHTMAP_ON that didn't declare DIRLIGHTMAP_COMBINED were stripped during player builds when using directional lightmapping. (UUM-68495)

• GI: Fixed Object.Destroy() call to an existing LightProbes object to remove internal managed data properly. (UUM-69475)

• HDRP: Set the 'Maximum Shadows on Screen' limit to 65536 in order not to exceed the maximum size of the buffer. (UUM-70329)

• IL2CPP: Fixed an incremental GC issue when using multidimensional arrays and full generic sharing. (UUM-74630)

• IL2CPP: Fixed for --additional-libraries flag and reworks build settings for uniformity. (UUM-71796)

• Mono: Fixed an exception that would occur when using System.IO.Compression.BrotliStream on Android. (UUM-73753)

• Mono: Fixed crash that occurred when accessing zip files on Linux distributions using zlin-ng (Fedora 40). (UUM-72446)

• Particles: Fixed an issue with invisible particles when shape Arc is set to 0 and Mode is set to Loop. (UUM-78236)

• Physics: Fixed an issue where Physics Debugger memory was being reported under default memory rather than physics memory.

• Profiler: Fixed an error being logged the the console when hovering the BackgroundPattern element in UI Builder. (UUM-68488)

• Profiler: Optimized profiler overhead to avoid frame time spikes during heavy load. (UUM-77998)

• Scene Manager: Added a save modified scenes popup on exiting. (UUM-78018)
