+C<< use Moose -metaclass => 'Foo' >> now does alias resolution, just like

+Added two functions C<meta_class_alias> and C<meta_attribute_alias> to
+L<Moose::Util>, to simplify aliasing metaclasses and metatraits. This is

+When an attribute generates I<no> accessors, we now warn. This is to help
+users who forget the C<is> option. If you really do not want any accessors,
+you can use C<< is => 'bare' >>. You can maintain back compat with older
+versions of Moose by using something like:
+
+    ($Moose::VERSION >= 0.84 ? is => 'bare' : ())
+
+When an accessor overwrites an existing method, we now warn. To work around
+this warning (if you really must have this behavior), you can explicitly
+remove the method before creating it as an accessor:
+
+    sub foo {}
+
+    __PACKAGE__->meta->remove_method('foo');
+
+    has foo => (
+        is => 'ro',
+    );
+
+When an unknown option is passed to C<has>, we now warn. You can silence
+the warning by fixing your code. :)

 The C<Role> type has been deprecated. On its own, it was useless,
 since it just checked C<< $object->can('does') >>. If you were using
 it as a parent type, just call C<role_type('Role::Name')> to create an
