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 (62 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 a crash that could occur when cancelling a build (e.g. BuildPipeline.BuildAssetBundles) while scripts are compiling.
Asset BundlesFixUUM-146331
Fixed an issue where performance could degrade and eventually fail when the Accelerator was under heavy load.
Asset PipelineFixUUM-146082
Fixed a NullReferenceException in SamplePostprocessor.OnPostprocessAllAssets that could sometimes occur when creating a Timeline asset.
EditorFixUUM-149739
Hierarchy: Fixed issue where the search filter was silently cleared (while the query block UI remained visible) after exiting Prefab Mode in Context.
EditorFixUUM-142149
Multiplayer: Removed redundant Button from Play Mode Scenario Validation Dialog.
EditorFixUUM-150409
Fixed case of project build failing with "IL2CPP error C2039: __entity is not a member of BlobBuilder" error.
EntitiesFixUUM-86534
Fixed a video player bug where the loop point reached callback would not always fire.
Game CoreFixUUM-133083
Fixed case of an error appearing incorrectly on ports when Graph.IsConnectionAllowed was overridden to permit connections between incompatible types. CheckNodeErrors now delegates type validation to CanAssignTo, consistent with how connection creation already behaves.
Graph ToolkitFixUUM-150703
The collapse button of a node with options is now enabled even when all the ports are connected. This allows pressing the collapse button to collapse the node just like it was possible by choosing Toggle Collapse or using Shift+Ctrl+O.
Graph ToolkitFixUUM-150163
Fixed crash caused by memory error related to per-Material constant buffer when OpenGL ES is used.
GraphicsFixUUM-150590
Fixed issue with a ghost prefab having multiple ghost prefab entity instances, such as when it is baked into multiple loaded subscenes. When loading, unloading and reloading the subscenes the ghost collection prefab would point to a previously unloaded/deleted entity prefab. This now correctly gets updated to an instance created from the reloaded subscenes.
Netcode for EntitiesFixUUM-146631
Fixed an issue where a dynamic body with a rotation constraint would bounce off surfaces despite zero bounciness.
Physics 2DFixUUM-150990
Fixed case of the Paint Texture tool keeping a replaced Terrain Layer selected, which showed the old layer's settings in the Inspector and added it back to the Terrain Layers list on the next paint stroke.
TerrainFixUUM-134352
Fixed ellipsis line-breaking recursion when the font lacks an ellipsis glyph and Ellipsis overflow mode is selected.
uGUIFixUUM-134066
Fixed case of a backdrop-filter element showing a scaled-down copy of the backdrop in the in-scene UI authoring viewport when display scaling is above 100%.
UI ToolkitFixUUM-148867
Fixed case of the move cursor being displayed over elements using the Relative position mode in the UI Viewport.
UI ToolkitFixUUM-150456
Fixed issue with the Hierarchy offering Create GameObject menu items in the UI authoring stage, where the new GameObject was created outside the stage and never appeared.
UI ToolkitFixUUM-145535
Fix to skip the SSAO pass when the active renderer does not provide the camera depth/normals textures.
