Profiler
Added build target support for QNX 7.1 with io-sock.
QNXFeature
Added --qnx-network-stack option to allow selection of new io-sock QNX7.1 variants.
QNXFeature
Added Smart Strings, a built-in module based on SmartFormat for formatting dynamic strings with named placeholders, pluralization, and conditional logic.
Scripting
Unity Player and Editor binaries now export a C symbol named UnityScriptingBackend. Its value indicates the scripting backend the binary was built with, such as IL2CPP, CoreCLR, or Mono, so external tooling can identify the backend by inspecting the binary without running it.
ScriptingFeature
Introduced a new fast build mode in the Shader Build Settings, automatically converting keywords to dynamic branching and making builds much faster for iteration purposes.
ShadersFeature
Added the localization module, an improved version of the Localization package. Migration support is available. For more information, refer to the documentation.

URPFeature
Added support for stencil in Shader Graph.
URPFeature
Added: URP Tonemapping now offers an AgX mode in addition to Neutral and ACES. AgX is a modern display transform that desaturates highlights as it compresses them, avoiding the hue shifts and clipping that can appear in over-exposed regions with ACES. It exposes two controls, Contrast and Mid Gray, and works in both SDR and HDR grading modes.
URPFeature
Modern Screen Space Ambient Occlusion in URP is now public. Existing SSAO Renderer Feature settings are no longer applied. To get the same SSAO results as before, follow the help box in the SSAO Renderer Feature inspector and copy the parameters (shown as inactive) into a Screen Space Ambient Occlusion Volume Override.
URPFeature
Input System rumble support for visionOS.
VisionOSFeature
Added support for building Player that uses up to 16 GB of WebAssembly memory (Wasm64).

Replaced Animation Window clip selector dropdown with a searchable dropdown.
AnimationImprovement
The Animator Window's compact mode Layers dropdown now has a search bar.
AnimationImprovement
Reduced memory consumption in Release builds. In Release builds, Profiler.GetTotalAllocatedMemoryLong() and Profiler.GetTotalReservedMemoryLong() now report the size the allocator actually reserved rather than the size that was requested, so a higher value than before does not mean that more memory is used.
Apple TVImprovement
Improved the security of model import by updating the bundled Autodesk FBX SDK to 2020.3.11, addressing two buffer-overflow vulnerabilities in FBX file parsing.
Added clarification detail to.
Asset PipelineImprovement
Improved Memory Profiler attribution of Asset Database native memory, which is now reported under named AssetDatabase roots instead of as unrooted memory.
The NativeFormatImporter now run out-of-process when "parallel import" (in ProjectSettings/Editor) is ON.
Asset PipelineImprovement
The VisualEffectImporter now run out-of-process when "parallel import" (in ProjectSettings/Editor) is ON.
Asset PipelineImprovement
Added new UnityAudioEffectDefinitionFlags_UseOutputChannelCount so Ambisonic decoder native audio plugins can use the full output channel count of the project rather than be fixed to the input clip channel count.
AudioImprovement
Added profiler markers to Scriptable Audio Pipeline Generators created from Audio Clips, and improved heuristics of the decode-ahead system to avoid slower in-place decoding.
AudioImprovement
Added profiler section for Scriptable Audio Pipeline.
AudioImprovement
Architectural improvements to remove most main thread stalls ("Flush DSP connections" profiler marker) or inversely audio drop-outs, when adding / removing Audio Sources, effects and so on, especially under pressure.
AudioImprovement
Changed some error messages during Content Directory builds when an included Asset has error messages to make easier to find the culprit asset and understand the underlying error.
Improved Content Directory build dependencies for LOD stripping in assets and scenes to avoid re-build them when the LOD stripping level is changed without impacting them.
Build PipelineImprovement
Section headers in the Build Analysis window now highlight across their full width when hovered.
Build PipelineImprovement
Updated the bundled 7-Zip to version 26.02.
Build SystemImprovement
Updated the bundled 7-Zip to version 26.03.
Build SystemImprovement
Player builds no longer launch the Burst AOT compiler when no user assemblies reference Burst, speeding up build time significantly for projects that do not use Burst.
The Burst compiler server now starts asynchronously during editor initialization, reducing editor startup time.

UUM-146006: LoadUnityMonoAssemblies startup phase is ~2.5x slower when opening the Editor on Windows
Steps to reproduce: Create or open any Project on Windows with Internal Mode enabled Observe the Startup Launch Screen and the time for "LoadUnityMonoAssemblies" Actual results: LoadUnityMonoAssemblies ~1.28s (a7) → ~3.16s (b1) — ~+1.9s, ~2.5×, every run.

CoreImprovement
Cherry-picked an upstream JIT fix that corrects an inverted Tier0 box-sharing guard, so Enum.HasFlag calls compiled at Tier0 get an exact-typed box and elide the allocation entirely instead of boxing both operands on every call (upstream dotnet/runtime #130590).
CoreCLRImprovement
The bundled CoreCLR runtime has been updated to a newer .NET 10 (release/10.0) servicing build, incorporating upstream fixes across the JIT, GC, COM/interop and cryptography, plus platform-specific fixes for Windows, Linux, macOS, Android, iOS and the browser.
