Hotfixes are cumulative; that is, the latest hotfix includes all of the fixes of earlier ones. It is necessary to install only the latest hotfix to get all available updates. This means that higher numbered hotfixes contain the bugfixes present in their lower numbered counterparts. All of the files in a given hotfix should be used together for proper operation.

Often the only component that is updated is the SE JAR file. Occasionally other components such as native code, or native adapter(s) will be updated.
