The update brings native mapping of PHP types to HTML attributes where null removes attributes entirely, booleans control attribute presence, and arrays serialize automatically for class/style/data attributes. It includes runtime type checking to catch errors during development, enables strict types by default, and adds a nullsafe filter operator (?|) for handling null values gracefully. The release also introduces syntactic improvements like n:elseif and provides a migration mode to safely upgrade from version 3.0. ## Full article daily.dev links to this article rather than hosting it.
