This is a minor release with security and reliability fixes only. - You are encouraged to update as soon as possible.

an oversight in the portable version of fgetln() that allows + attackers to read and write out-of-bounds memory

multiple denial-of-service vulnerabilities that allow local users + to kill or hang OpenSMTPD
