### Deprecated Methods
Some methods within the CiviCRM Code base that extension developers have been relying on have now been deprecated:
*`CRM_Core_Error::fatal`
Extension authors should replace fucntion calls with either `throw new CRM_Core_Exception` or `throw new <insert CiviCRM Generated Exception>` or `CRM_Core_Error::statusBounce` if the error is being generaged from a form.
