The PHP developers recently released versions 5.4.40, 5.5.24 and 5.6.8 that fix several bugs. We’ve upgraded PHP 5.4, 5.5 and 5.6 on our servers as a result.
These changes should not be noticeable, but in the unlikely event you experience any trouble, don’t hesitate to contact us.
In addition, the company that makes the Zend Guard Loader software has finally released versions compatible with PHP 5.5 and 5.6, so we’ve made that option available in the “PHP Settings” area of our My Account control panel (with all the usual caveats about why encoded scripts are inherently unreliable).
