===============================================================================
Compatibility
===============================================================================

* PHP 5.3

This version requires at least PHP 5.3, older versions of PHP are not supported
anymore with TYPO3 4.6.

* ImageMagick/GraphicsMagick

...

* PHP __constructor() methods

The old PHP 4 style class constructors, which have been the same as the class
name have been changed to use the PHP 5 __constructor() syntax. This is
considered as breaking change if extension called the old contructor of an
object directly.
