Taskflows use the upgraded version 10.8 of the Saxon libraries. Version 10.8 of the Saxon libraries offers improved security, performance, and scalability. After you upgrade to the May 2024 release, you must republish all the taskflows to use version 10.8 of the Saxon libraries. If you do not republish the taskflows, Data Integration continues to use the earlier version of the Saxon libraries.
