Improvements

Note Status

As a result of this change, the following UI components will have better visibility of selected text and items:

  • Explorer Tree - Filter workspace
  • Properties Widget - Filter Properties
  • Output Widget - Filter, Search bar (Ctrl / Cmd + F)
  • Find And Replace Widget - Find…

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

Now, select() is faster when used on variadic arguments (when the second argument is ...). The gains scale with the number of variadic arguments, with 10 arguments it’s ~3x faster.

Pending

Luau compiler now optimizes table literals where keys are constant variables the same way as if they were constants. For example:

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

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
