A couple of last minute corrections were made to the Create Checks option and the option to print statements with the checks. If you will be printing your own Safe Harbor checks, make sure you are running on at least version 7.77.1650 so that you have these changes. Use the Check for Updates option on the Tools menu to download the latest version if you are running an older version.
If you are sending payment information to a third party administrator, these changes will not affect you.
