Added a Pinned libraries section to the MSBuild and NuGet policy page that lists the libraries Unity pins and their versions.

Improved the error messages shown when DirectX 12 runs out of memory, which previously reported an unrecoverable GPU device error.

Improved Editor startup time by avoiding an expensive full-assembly type scan during mode discovery

Improved the CacheServerV2 integration tests by spawning a single cache server for the suite of tests rather than spawning a new server for each test. This prevents the instability in restarting the server process between tests.

Improved the description of what's contained in the Multiplayer sample install flow.

Project Auditor: detect boxing of structs used in List comparisons.

Project Auditor: redesign the home page. Move URP migration wizard to the home page.

Project Auditor: The error shown when the rules package is missing now names the com.unity.project-auditor-rules package.

Shader compilation work is now captured in the buildreport.json Chrome trace profiling file that's generated during editor player builds allowing the time taken processing shaders to be visualized and inspected.

Updated layout, tooltips, and reset behaviour for some fields in the Skinned Mesh Renderer component.

Fixed performance metrics being reported without a sum, which prevented average values from being calculated.

Calling BlobArray<T>.ToArray on an element type that contains BlobArray or BlobPtr fields is now reported as compile error UAC0044, in addition to the existing runtime exception.

Improved live baking diff performance in worlds with many entities.

Improved the performance of ComponentLookup, BufferLookup and TransformLookup methods that check whether an entity exists or has a component.

Added a Material Resolution setting to the Surface Cache Global Illumination renderer feature. New renderer features use Medium, and existing ones keep Very High.

Added a World Culling view, an option to exclude the Scene view from entity culling, and culled and live entity and chunk counts to the Surface Cache section of the Rendering Debugger.

Added Entity Culling settings to the Surface Cache Global Illumination volume override, which leave out entities that are beyond a distance from every camera, or smaller than a minimum size on screen, in pixels or degrees.

Added material atlas usage to the Surface Cache panel of the Rendering Debugger.

Added support for cutout materials in Surface Cache GI.

Improved Memory Profiler attribution of lighting native memory, which was previously reported as Unrooted.

Tweaked presets in Surface Cache GI to make denoised results look better.

Graph Toolkit editor windows no longer keep views and models alive in static caches after they are closed.

Improved CPU performance of ray tracing acceleration structure builds when the structure contains many static instances or has had many instances removed.

Improved Render Graph Viewer empty state message when connected to a player

Mesh-related memory should now be correctly labeled in the memory profiler

Reduced render thread time for render passes whose renderer list is empty after filtering, when graphics jobs are enabled.

Reduced render thread time on Metal for buffers updated every frame, such as the constant buffers of the Universal Render Pipeline.

Improved fallback search handling of special characters.

A boxing allocation is no longer performed when the boxed value is immediately discarded.

Calling GetType() on a boxed value type, including comparing the result against a typeof() expression, no longer causes a heap allocation.

Casting between an enum and its underlying integer type through object no longer causes a heap allocation.

Expand inlining heuristic to inline small simple methods.

Fixed static field accesses not throwing an exception when a class's cctor failed on some platforms.

GC.KeepAlive no longer causes a heap allocation when it is passed a value type.

Generated code for some cases of pointer arithmetic is now vectorized by Clang.

Improved inlining heuristic to expand set of possibly inlined methods.

Improved performance of type checks when storing references into arrays.

Improved performance of typeof and Object.GetType().

Removed un-needing boxing that can occur with the if (x is Type t) pattern.

Updated Math.Pow and MathF.Pow to match behavior of .NET.

Volatile fields and the volatile. prefix use acquire and release semantics instead of a full memory barrier.

Volatile.Read and Volatile.Write use acquire and release semantics instead of a full memory barrier.

Fixed Append being allowed when changing Symlink Sources option

iOS builds now use .NET 10 base class libraries.

Make AppDelegate and SceneDelegate methods in UnityPlayer public

Linux IL2CPP builds now use .NET 10 base class libraries.

Improved the accuracy of bouncing, which is now resolved after the rest of the contact solving each simulation step.

Improved the performance of contact creation and shape queries.

Improved the performance of contact solving and of finding new contact pairs.

Improved the performance of contact, trigger, body update, and joint threshold callbacks, which no longer query the engine for each event to find its callback target.

Improved the PhysicsCore2D Profiler to show timing information in a consistent hierarchy which indicates not only the times taken but also where in relation to other timings they occur.

- Improved module pinning UX in the profiler window. It is now possible to pin modules by hovering on a module chart header and clicking the pin icon, or directly from the Profiler Modules dropdown.

Added a draggable divider below the pinned modules. When the pinned modules don't fit in the pinned area, the area scrolls and you can drag the divider to resize it.

Improved native memory attribution so several kernel, plugin and file system allocations are reported against a named root instead of Unrooted in the Memory Profiler.

Reduced GC.Alloc hook overhead when profiler is disabled or there are no active ProfilerRecorders for GC.Alloc metric.

Replaced the Scene View orientation gizmo with a lighter UI Toolkit implementation, reducing its per-repaint cost and giving it a new flat-icon style.
