We have fixed encoding issues for some code that uses built-in functions or classes or inherits classes from built-in ones. The issue was related only to PHP 5.4. The update is recommended for all users of version 9.x. If you had issues running PHP 5.4 protected files, please re-encode your files after upgrading to version 9.0.3 and install the latest PHP 5.4 loader for your OS. Fixed PHP 5.4 loaders are included in this version update.
