We added support for XDebug in the preview engine so you can use it right out of the box. When configuring your project you can select Xdebug or DBG. When the debug session starts, Apache will load Php with the configured debug engine.

XDebug has a lot more features than DBG and it is more stable in Php 5 so I recommend you using it instead of DBG.

We also made some improvements to the call stack window where you can select viewing the file name where the function is in as well as the line in the code where the function was called. These are settings you can control by right clicking in the call stack window.
