Backend/Frontend file types allowed in selected directories are now case–insensitive. In the past you would have to specify a case–sensitive extension to be allowed in the .htaccess / Web.config / Nginx Conf maker. For example, allowing the png extension would cause a file named example.PNG or example.Png to return a 403 Forbidden error when you try to access it. Starting with this version the file extensions are case insensitive. Obviously this only matters on case–sensitive filesystems, e.g. ones used on live servers running Linux.
