DownloadsII 5.1.2 is an immediate security release fixing a severe CSRF security issue. Abusing this issue can lead to the unwanted removal of files, images and comments. So I recommend to update your site as soon as possible.
Next to that some other issues were fixed like PHP warnings when you are running PHP 5.3.
