Version 2.1 of the Hack Clock now provides IFTTT event publishing support - so you can fire off events at IFTTT! Turn on your bedroom lights when the alarm goes off!
I have also added Google Music (unofficial) support. If you provide your username/password in /etc/hack-clock.conf, you can stream "I'm Feeling Lucky" radio!
Version 2.1 is likely going to be the last minor release for a little while, and instead I will be focusing on bugfixes.
