Release Notes for 535

Updated the Collision Groups Editor UI in studio to make better use of space and added the ability view collision toggles as a list or table.

Add unknown and never type to Luau, see the RFC: https://github.com/Roblox/luau/blob/master/rfcs/never-and-unknown-types.md

Add a three-phase rollout property "UnionsScaleNonuniformly" under workspace. The Nonuniform Unions beta will be transitioned to this three-phase rollout so that developers can begin using nonuniformly scaled unions in live games.

Improve UV layout and fix some bugs on Cylinder Parts.

Users should now be able to paste accessories into an avatar and the weld will be created properly

Improved inference of string.gmatch function: the types, and amount, of captures is now inferred when the pattern string passed to gmatch is a known constant.

Fixed a bug where the 'Format' right-click menu option in the Script Editor would be disabled.

Stop overwriting Mouse.Icon, UserInputService.MouseBehavior, and UserGameSettings.RotationType every frame in camera scripts. Forked versions of player scripts will need to be updated to get this fix.

Fix an issue that sometimes text is blurry when parented under CanvasGroup.
