I've changed my filezilla settings to always upload in binary. Uploaded the repository file and confirmed that it's the same size (677b). I stuck a copy of the IPBanning add-on with it's version set to 2.0.0 in my add-ons folder, and updated the repository to report the latest as being 2.1.0, but when I start the game it makes no report on an update. It worked on updating your other add-ons.
