Version 1.2 of WP-Cron is now officially available.
This version fixes a small error with calculating when the next daily event should occur. Daily actions should now actually occur! =)
Also included with this version is an updated
wp-cron-moderation.php, which sends hourly notifications of new comments awaiting moderation.
Here's the list of all WP-Cron plugins included:
WP-Cron Dashboard: uses WP-Cron to update the data in your WordPress dashboard (roughly) every hour.
WP-Cron Future Pings: suppresses outgoing pingbacks and trackbacks when publishing a post with a date in the future; then uses WP-Cron to periodically check if any such future-dated posts are visible, sending pingbacks and trackbacks as necessary.

WP-Cron Gravcache: refresh your cached Gravatar image files on a daily basis.
[ Experimental, and may not yet be fully functional! ]
WP-Cron Mail: periodic check of your secret email account for blog-by-email. This is a near exact copy of the original wp-mail.php, which may or may not be sufficient for your needs. See also http://codex.wordpress.org/BlogbyEmail
WP-Cron Moderation: sends an hourly email summary of new pending moderation requests. That is, if you get two new comments at noon, you'll receive one email notififying you. If you take no action, and receive no new comments, you will not get pestered again. You will only receive one email per new comments per hour.
WP-Cron Reminder: sends out a generic reminder email to the blog admin (roughly) every 15 and 60 minutes. You can use this to prove to yourself that WP-Cron is working.
