Hi Jerry - I don't think this change is documented in our official documentation. Could you either re-open this issue or do a new issue so we don't forget to do that? I'm happy to "edit" someone else's first draft of updates, or, if I get a chance I might try to update this myself (but I'm kind of swamped with other work these days).
