- Stefan Krause pointed out that libcurl would wrongly send away cookies to
sites in cases where the cookie clearly has a very old expiry date. The condition was simply that libcurl's date parser would fail to convert the date and it would then count as a (timed-based) match. Starting now, a missed date due to an unsupported date format or date range will now cause the cookie to not match.
