How this number is computed

Composite = sum of sub_score × weight across six metrics. Sub-scores are percentile-rank(log1p(min(raw, p95))) within the Update/Supported cohort (41 releases). Sub-scores for lower-is-better metrics are flipped to 100 − percentile.

* = raw value was clipped at the cohort 95th percentile to prevent outliers from compressing everyone else's scores. Sub-scores marked "med" substitute the cohort median where the input was missing (e.g. first patch on a minor line has no prior patch for net-fix delta).

Fixed crash drawing debug visualisation for an agent with small radius and a far away destination.
AIFixUUM-133552
Added a notification in the FBX Importer UI when FBX takes aren't used by any clip.
AnimationFixUUM-130850
Reduced critical crashes when minimizing (via Alt-Tab) "Exclusive Fullscreen" window in Player by pausing rendering. Other modes and graphics APIs are not affected. For better stability consider using "FullScreenWindow" (borderless) mode .(https://devblogs.microsoft.com/directx/demystifying-full-screen-optimizations/).
DX12FixUUM-134743
Fixed an issue where a layout with Locked Project Browser could spam the Console with log errors.
EditorFixUUM-137174
Fixed an issue where clicking Delete in the context menu on a selection of multiple blocks in a context node would only delete the block that was clicked on instead of the entire selection.
EditorFixUUM-137656
Fixed an issue where HDR Colors weren't correctly recorded in the Animation Window.
EditorFixUUM-83771
Fixed deadlock race condition when loading and unloading content files in the editor.
EditorFixUUM-137677
Specific ScriptableObject asset names no longer cause warnings when opening the Build Profiles window.
EditorFixUUM-135389
Fixed issues with the subgraph node right-click menu. Convert to Asset Subgraph and Unpack to Local Subgraph menu items are no longer duplicated when multiple valid subgraph types exist in the graph. These actions no longer allow changing the underlying asset type of the subgraph. Find Asset in Project now correctly pings the associated asset in the Project window.
Graph ToolkitFixUUM-137211
Graph Toolkit: Removed the Disable Node entry from the right-click menu as the feature is incomplete. This was not meant to be public yet.
Graph ToolkitFixUUM-137461
PhysicsHingeJoint can now be "unpinned" which provides rotational constraining only with the point-to-point constraint, effectively allowing the PhysicsBody to move while having rotational-only constraints applied.
Physics 2DFixUUM-137810
Update Box2D to include various bug-fixes and improvements, most notably being contact recycling to improve contact performance during simulation.
Physics 2DFixUUM-137810
Fixed issue where loading a Profiler capture while actively recording would mix loaded data with frames that hadn't finished processing.
ProfilerFixUUM-134269
Fixed Profiler screenshots not recording on Vulkan.
ProfilerFixUUM-126495
Fixed corners on Mac that would show an invalid pixel on the very edge.
UI ToolkitFixUUM-122540
Fixed different VectorImage size when importing SVGs with "Arc Encodings" vs "Basic Triangulation".
UI ToolkitFixUUM-121289
Fixed VectorImage import ignoring the viewport.
UI ToolkitFixUUM-133924
Fixed viewport options not exposed for SVG VectorImages.
UI ToolkitFixUUM-138244
Patched missing pixels caused by some T junctions.
UI ToolkitFixUUM-121344
Fixed an issue where on-tile PostPro had a different result compared to traditional PostPro when Color Space was set to Gamma.
URPFixUUM-135686
Fixed an issue when building and running Meta Quest applications with texture compression targeting enabled.
