* Type inference of `a and b` and `a or b` has been improved (Fixes https://github.com/Roblox/luau/issues/730) * Improved error message when `for ... in x` loop iterates over a value that could be 'nil' * Return type of `next` not includes 'nil' (Fixes https://github.com/Roblox/luau/issues/706) * Improved type inference of `string` type * Luau library table type names are now reported as `typeof(string)`/etc instead of just `string` which was misleading * Added parsing error when optional type alias type parameter wasn't provided after `=` token * Improved tagged union type refinement in conditional expressions, type in `else` branch should no longer include previously handled union options
