 * Fix missing macOS wheels for regular (non-freethreaded) Python 3.14+
   (https://github.com/python-grimp/grimp/issues/317).
+* Fix missing Linux aarch64 wheels for Python 3.15 by building on a native arm64 runner.
+* No Python 3.15 wheels are published for Linux armv7, s390x or ppc64le, or for any musllinux
+  target, since the Docker images used to build those don't yet support Python 3.15. Previously

 * Fix imports in the ``else`` (or non-type checking ``elif``) branch of an ``if TYPE_CHECKING:``
   statement being excluded by ``exclude_type_checking_imports``, even though they run at runtime.
 * Fix panic when a module declares its encoding using a name that Python accepts but that isn't a
