+* Fonts: the templates now support a new `fontAliasName` that you can use to change the `typealias`'s name from `Font` to something else. For example: this is useful when working with SwiftUI which already defines a `Font` type. Note that as this `typealias` is deprecated (see deprecations above), this template parameter will also be removed in the next major release.
