### Breaking changes
+* Most builtin functions that return a value can no longer be used as a call statement. [tint:1844](crbug.com/tint/1844)
* The `sig` member of the return type of `frexp()` has been renamed to `fract`. [tint:1766](crbug.com/tint/1766)
* Calling a function with multiple pointer arguments that alias each other is now a error. [tint:1675](crbug.com/tint/1675)
* `type` deprecation has been removed. `alias` must be used now. [tint:1812](crbug.com/tint/1812)
