Just .54 and .55. Yet oddly we can filter issues by product version of the main view issues page...that page has options for .54, .55, .56
Maybe a permissions thing and staff can probably see .56 in the dropdown?
This also means that when we filter issues (product = 0.56)on the view all bugs page (http://feedback.dayzgame.com/view_all_bug_page.php) we see zero bugs.
