In PeopleTools 8.56, JQuery was updated to Version 2.1.4, as part of this upgrade these files are no longer part of the Web Server install for the Gateway. The old files will remain under the directory (map/defaults) in order for the Gateway to support older tools releases. For 8.56 and above these files are part of the PT_MAP_FRAMEWORK Template. When a File Sync is performed these files are propagated to the Gateway. This allows different versions of JQuery/ JQuery Mobile to coexist on a single Gateway, as well simplifying the update process for these files.
