## Swift 6.1

* [#78389][]:
Errors pertaining to the enforcement of [`any` syntax][SE-0335] on boxed
protocol types (aka existential types), including those produced by enabling
the upcoming feature `ExistentialAny`, are downgraded to warnings until a
future language mode.

These warnings can be escalated back to errors with `-Werror ExistentialAny`.

* Projected value initializers are now correctly injected into calls when
an argument exactly matches a parameter with an external property wrapper.
