I am glad to hear that the new release is “good to go”, but I am disappointed that the developer released an upgrade without testing on PHP 5.2. Your plugin requirements state:
PHP 5.2.4+ (same as WordPress 3.3.2)
WordPress: 3.3.2+
As such, all releases should be tested for PHP 5.2.4, especially since there are major changes between PHP 5.2 and 5.3.
