I have released Spigot 2.2. The primary purpose of this release is to support the use of any arbitrary field in the incoming feed in the format of the outgoing message. Before Spigot limited you to the title or link, but now you can have more options, including author, etc.
This update requires a database schema change as well as an update to your configuration file. The new version will prompt you to upgrade these if necessary. I have provided an upgrade script in the git repo to handle this upgrade for you. New users have nothing to worry about.
