Release notes for 668

Adds support for multiple controllers on Xbox and PlayStation.

Studio Debug Assistant error actions in the output context menu now retain on exiting Play mode.

In the new Explorer, selected instances now have darker text.

Introduces support for the deprecated attribute. Luau functions and table methods marked for deprecation lead to linter warnings when used.

Introduces three-phase rollout for updates to the physics sleep system.

In Luau's New Type Solver, fixes crashes that occurred when the index type function was used cyclically to define the indexer of a table type.

Adds preset selection to the visual editor for AudioEmitter.DistanceAttenuation and AudioListener.DistanceAttenuation.

Adds support for a new @self alias to directly access children when using require-by-string, and deprecates the special treatment of ModuleScripts named Init or init.

In Luau’s New Type Solver, decreases the occurrence of "leaked free type" errors.

Add a new default @self alias as an autocomplete option when using require-by-string.

In Luau’s New Type Solver, resolves some crashes related to using type assertions with a leading union or intersection type, such as:

local x = 42 :: | number 
                | string

Adds section headers to the Draggers dropdown in the Nex Gen Studio toolbar.

Allow users to specify body mesh, or layered or rigid clothing and accessories for input models of Avatar Setup.

Mac Studio now supports pinch to zoom.

The Beta Constraint tool now correctly resizes attachment adorns in accordance with the spinbox value.

In the new Explorer, the scroll bar now snaps to the edges when you go out of bounds, rather than stopping still.

In the new Explorer, fixes broken box select behavior.

ContentProvider:PreloadAsync() now supports SurfaceAppearance and MaterialVariant objects.

RunService:IsRunMode() no longer incorrectly returns true when run on a server started from Play mode.

RopeConstraint, RodConstraint, and SpringConstraint objects are now visible by default when you create them using the Beta Constraint tool.

Fixes long heap profiler entries to be properly cut off instead of disappearing.

In Luau's New Type Solver, fixes an internal compiler exception when passing the same argument twice to table.freeze.

Ray:ClosestPoint() and Ray:Distance() now produce the expected values. Both methods now use a unit vector to perform the projection in the underlying computation.

Fixes an issue with glass refraction when unified lighting is enabled.

Mutually recursive types must agree on their type parameters. This restriction always existed, but it caused random behavior if it was broken.

Fixes Studio selections counting as Triangles and Drawcalls in scene statistics.

Fixes ScaleTo behavior for Trail instances. Trail.TextureLength should not be scaled in Enum.TextureMode.Stretch mode, and Trail.WidthScale should never be scaled.
