In the Softaculous panel, it would not let me update my phpMyAdmin from 4.8.0.1 to anything higher because the requirement was for PHP 5.6. However, according to their site, 4.8.3 is compatible with PHP 5.5.
As a workaround, I manually installed. 4.8.3 and Softaculous recognized the version mismatch and it updated the install version information. I have a feeling that when 4.8.3+ comes out, I will run into the same issue.
