Release Notes for 512

SoundGroups will now support nesting via parent-child relationships

Added navigation and general errors telemetry for WebView2 in Studio.

Luau refinements can now narrow unions that are tagged in some way and will select the options that makes sense.

type Cat = {tag: "Cat", name: string, catfood: string}
type Dog = {tag: "Dog", name: string, dogfood: string}
type Animal = Cat | Dog

if animal.tag == "Cat" then
  local cat: Cat = animal
elseif animal.tag == "Dog" then
  local dog: Dog = animal
end

GlobalWind

Luau compiler now optimizes table literals where keys are constant variables the same way as if they were constants, eg

local r, g, b = 1, 2, 3
local col = { [r] = 255, [g] = 0, [b] = 255 }

Adding the capability for new microprofile scopes to the conditional on FFlags

The colors of these will now be the same as other parts of the Roblox Studio UI: Text boxes and dropdown lists.
