QTads 2.1.3 was released on 2012/03/29. Current version in portage is 2.1.2. Renaming the current ebuild is enough for a version bump. 2.1.3 is a good candidate for stabilization as it's a bugfix-only release, with no new features or functionality added: https://sourceforge.net/projects/qtads/files/qtads-2.x/2.1.3/readme/view
