CodeIgniter 3.1.1 Released

I'm running into errors due to the changes made to the Upload Library.  This happens on two Windows servers with PHP: one is running PHP 5.5.16 and the other is running PHP 5.5.34.  When a file upload is initiated via a form, the page gives a generic 500 message with zero error message logged in the PHP error log.

I think it is due to changes in the _file_mime_type function, but I am going to do an exhaustive test to see if I can get you more information.

After digging into this...the error relates to the removal of this:  if (function_exists('finfo_file')) { }.  If the php_fileinfo.dll is not initiated, the function now bombs out due to the removal of that contingency.
