Glad to see they've updated the release notes. Wasn't there when i looked earlier yesterday

Indeed this shouldn't be the workaround, as this will force you to make all items optional

What do you mean by it will break, how so? (just interested because im facing some issues with the self._$backingData issue)

Same for me. @Model macro doesn't seem to like settings default values, but Cloudkit requires it for non-optional values...
