=====================================================1. Changes in Zend Guard===================================================== 1.1 Changes in Zend Guard from version 5.5 to 6.0=====================================================

* Full support for PHP 5.4* Dropped Support for PHP 5.2 ( Guard 5.5 should be used )

================================2. Known issues and Limitations================================

General:--------* Encoding/obfuscation for PHP 5.4 is not compatible with PHP 5.3 andearlier releases, and vice versa. That is, a file encoded to run on PHP 5.3will not be loaded on PHP 5.4 and vice versa.Workaround: Encode your application separately to run on PHP 5.3 and PHP 5.4.

Encoding:---------* Relative names do not work with --ignore and -exclude-file* Using inexact file names (different cases, / instead of \, or not full paths) does not work with --ignore and --exclude-file (Windows only)* "Work only with encoded files" option does not work if it is not applied for all files* Extending stdClass gives a blank output when a file is encoded

Obfuscation:------------

* Using mbstring.func_overload with obfuscation requires exporting functions that are overloaded.
