.223 was only available direct from the Update Catalog. It was never (AFAIK) delivered through Windows Update, probably because it was identical to .222 in all respects except one...
https://support.microsoft.com/en-us/kb/3197356This cumulative update resolves an issue in which some sites do not load in Microsoft Edge after KB3194496 is installed. This issue occurs when a user is on a page that specifies a character encoding hint that isn't present on the computer, and the user browses from that page to a location that uses HTTP redirection.
In the scheme of things, this one is a routine monthly 'patch Tuesday' release.
