I noticed some locale-formatting tests breaking in Chrome 110 and traced this back to a change in Unicode CLDR 42.

You can find this by searching for "y-MM-dd" in the linked changelog.

AIUI, the official recommendation is to use y-MM-dd, and M/d/yy is particularly ambiguous in Canada, at least relative to the US.

Thought I'd float in case anyone knows more, or has been using the "en-CA" trick to get American-ish dates with YYYY-MM-DD short dates.
