WSO2 introduces the WSO2 Update Manager (WUM), which is a command-line utility that allows you to get the latest updates that are available for a particular product release. These updates include the latest bug fixes and security fixes that are released by WSO2 after a particular product version is released. Therefore, you do not need to wait and upgrade to the next product release to get these bug fixes. For information on updating WSO2 API Manager with the latest available patches (issued by WSO2) using the WUM tool, see Getting Started with WUM in the WSO2 Updates Guide.
