1.4.1

By default, Spatie/Ignition sets the error_reporting level to -1.
Now it respects the current level, for example, if set in php.ini or explicitly in index.php:

Mage::setIsDeveloperMode(true);
error_reporting(E_ALL & ~E_DEPRECATED & ~E_STRICT & ~E_NOTICE & ~E_WARNING); 

Will be displayed all errors except for deprecated, strict, notice, and warning.
