Release notes for 664

New Explorer - Fix funky hovering when hovering over a dropdown item or search box.

Adds entry to properties widget for properties of the Content type.

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

In Luau's New Type Solver, greatly improves the ability to infer types of table literals, reducing the number of invariant subtyping failures, such as in:

local x: foo = {abc = 100} -- ok
local y: foo = {abc = 10 * 10} -- Previously errors, now ok

For the New Luau Type Solver, fixed some instances where non-nil variables became nil after function or method calls, such as in:

--!strict
local RunService = game:GetService("RunService")
if RunService:IsRunning() then
  -- BEFORE: `RunService` now has type `RunService?`
  -- AFTER: `RunService` still has type `RunService`
  return RunService
end
