I've just released an update to Catfood Follower. Follower is a tool for Twitter users that allows you to find and remove friends who have stopped following you. It also allows you to automatically follow anyone who starts following you (but does not send automatic DMs).

Follower 1.10 is much better at handling Twitter API limits. Rather than failing to update it will wait until the current limits expire and then keep going. It will work much better for people with many accounts, friends, or followers. 1.10 also uses the new cursor method for paging through lists which is more reliable.
There's also a new window that shows progress when automatically processing rules:
This is now the default when running Follower.exe with no command line argument. If you prefer the old behavior run Follower.exe /silent and the update will run without any notification.
It's also now possible to cancel Follower, either from the test window or when running automatically (as long as you're not using the /silent switch).
