1.0.3 has been released fixing a number of bugs, particularly with executing campaign decision paths.
Please note that executing the first action of a campaign no longer occurs immediately when a lead is added to the campaign or when the campaign form is saved (which could result in hitting PHP limits if there are a large number of leads). Please review the Executing Campaign Actions section of Mautic's documentation on how to setup the necessary cronjob to handle this.
