sshguard update question

[wgstarks]

When installing the recent update to sshguard I got the following message-

You may need to manually remove /usr/local/etc/sshguard.conf if it is no longer needed.

My question is, is this file just a remnant of a previous version that wasn't removed as a part of the update or will it be recreated constantly and I'll need to remove it with every update?
Not sure why it must be removed manually?
