Breaking: #77919 - Changed DateTime::ISO8601 to DateTime::ATOM¶
See forge#77919
Description¶
The format DateTime::ISO8601
is not compatible with ISO-8601, but is left this way for
backward compatibility reasons. The constant DateTime::ATOM
or DATE_ATOM
is used
instead when rendering JsonViews via Extbase.
