#release(release_name, filenames, release_notes = "", release_changes = "", package_name = nil, preformatted = true, processor = Processor::ANY) ⇒ Object

Creates a new release containing the files specified by filenames (Array) and named release_name. Optional parameters are processor (which should be one of the Processor constants), release_notes, release_changes and preformatted which will appear on the releas page of the associated project. The package_name parameter will help choose from the possible multiple packages for a release. TODO: consider using a hash based signature with symbols. This is getting big!
