Broadphase.Tree.Clone() now allocates node storage that is sized to its capacity rather than the source tree's Length. This fixes an OutOfRange error that may be observed when a full multi-threaded broadphase rebuild is performed on a densely-packed, cloned world.

Search changes, fixes, and known issues across Unity releases.
Fixed the behavior of the combine functions for converted materials so they match the built-in physics one. This change is opt-in and can be enabled from the Unity.Physics project settings pane.
Vertex counting to select the correct rendering index format for a convex mesh that has more than 65535 vertices when using a combined mesh
Collider.ToMesh() leaked an intermediate mesh for every convex, mesh and terrain collider it converted. These meshes are now destroyed once they are combined into the returned mesh.
check actual built-in materials, instead of just their names, when converting assets.
Check materials is all Renderers, not just MeshRenderers, when scanning for items to convert.
Ensure command line URP converter scanning saves its report to a persistent location.
Fix a bug where having the material inspector and scene view on screen together causes error spam when using screen space reflections.
Fix a bug where reloading a scene would cause certain Blitter functions to stop working.
Fix a bug where URP attempts to use a stripped variant when using deferred rendering with additional light shadows disabled, but shadowmasks enabled.

The exposure feature no longer affects performance when disabled.
The Slope-Scale Depth Bias mode no longer produces shadow acne at low depth bias values or texel-aligned stripes on surfaces facing the light head-on. The slider now maps to a slope that never drops below the legacy mode's fixed slope, and a small fixed caster depth offset covers head-on receivers while the caster normal bias mode is active. The legacy mode is unchanged.
Unclamped exposure values could break. To solve this it is now clamped at +- 20
