I want to make sure that WordPress does not ping sites listed under "Update Services" in the Option panel when editing old posts. I know WordPress remembers which posts it has already sent pings for, but I'm worried that editing very old posts, before I started pinging sites, will cause a new ping.
Smart Update Pinger could be used with old versions of WP to force this behaviour, but it isn't available anymore. Do new versions of WP have the behaviour I want by default, or is there a different plugin I should be using for WP 2.0? I checked the Codex but it appears to be out of date in this area.
