Netcode for EntitiesChange
Source generators no longer log to Console.Out
Netcode for EntitiesChange
The GhostUpdateSystem's predicted ghost history backup lookup failure case now only attempts to rollback to the snapshot if said rollback isn't too severe. This change marginally worsens correctness in exceptional cases, but prevents egregiously large rollbacks.

SRP CoreChange
Migrate from UIDocument to PanelRenderer at Rendering Debugger Runtime UI.
SRP CoreChange
Shader and runtime-resource stripping decisions for diagnostic content are now driven by the build's Managed Code Variant (UNITY_ENABLE_CHECKS) instead of by the native "Development Build" flag. Builds using the Checked variant retain debug shaders and runtime resources even when the native binary is non-development; builds using the Release variant strip them even when the native binary is development.
SRP CoreChange
Various Scriptable Render Pipeline diagnostic features are now compiled into builds based on the new Managed Code Variant player setting:
SRP CoreChange
Available in Debug or Checked variants (UNITY_ENABLE_CHECKS):

SRP Core debug display managers, Render Graph Viewer support (audits, debug data, builds remote debug session), and the Volume panel.
Change
Available in Debug, Checked, or Instrumented variants (UNITY_INCLUDE_INSTRUMENTATION):
Change
HDRP HDDynamicResolution GPU frame-time debug overlay.
Change
Render Graph profiling sampler plumbing (RenderGraphProfilingScope, GetDefaultProfilingSampler).

TextMeshPro Mesh and TextMeshPro UI Mesh now name their internal Mesh objects in all build configurations. Previously the name was only assigned in development builds and the Editor.
TextMeshProChange
Changed some undocumented runtime behaviour of TimelinePlayable.CreateTrack.
TimelineChange
When a track is created, complex name generation and disambiguation logic would run, assigning a unique name to the track.
BeforeChange
When a track is created, if a name is provided, the track will have that name. If no name is provided, the track with have an empty, non-null name
AfterChange
If you create Timeline Tracks at Runtime and you rely on their names, validate that the names of your tracks haven't changed.

UI ToolkitChange
Unity Physics integrity checks are now compiled into Player builds whenever the Managed Code Variant is Debug or Checked. Instrumented and Release-variant builds continue to strip integrity checks. Users who want to disable them entirely can still set UNITY_PHYSICS_DISABLE_INTEGRITY_CHECKS.
Unity PhysicsChange
Adjusted SSR roughness to blur curve to more closely match reflection probe's.
URPChange
Allow stripping Film Grain textures when post processing is enabled but Film Grain is not used.

Overriding these properties at runtime via cmd.SetGlobalVectorArray / MaterialPropertyBlock no longer affects URP rendering; the constant buffer binding takes precedence.
URPChange
The _AdditionalLightsPosition, _AdditionalLightsColor, _AdditionalLightsAttenuation, _AdditionalLightsSpotDir and _AdditionalLightsOcclusionProbes shader properties are now in a persistent global constant buffer. Overriding these properties at runtime via cmd.SetGlobalVectorArray / MaterialPropertyBlock no longer affects URP rendering; the constant buffer binding takes precedence.
URPChange
The _AdditionalLightsWorldToLights and _AdditionalLightsCookieAtlasUVRects shader properties are now in a persistent global constant buffer. Overriding these properties at runtime via cmd.SetGlobalMatrixArray / cmd.SetGlobalVectorArray / MaterialPropertyBlock no longer affects URP rendering; the constant buffer binding takes precedence.
