I don't see much reason to change anything here. "Datetime" is not
a perfectly strict classification, eg it might or might not include
"interval" depending on context, and I don't want to try to make
that exact.
A more specific release note entry could be "Accept the spelling
'+infinity' for datetime types that accept infinity"; but I'm not
sure it's worth the extra verbiage.
