Ampullate Post Expiration
This is a fork of the original post-expiring plugin created by Piotr Potrebka (http://potrebka.pl) which has not been maintained for over 10 years.
Ampullate has extended its capabilities with a filters and a PHP constant, either of which can be used to define which post types can be expired. By default most custom post types that are public can be expired. This plugin is used by a few large clients of Ampullate.
