Payroll Year End ESU's

I am new to JDE payroll Year End Processes. From my understanding there are important ESU's that need to be applied as part of the Year end procedures. I was informed by my CNC team that beginning this year that these ESU's will not be available. Is this true? This does not make any sense, however if it is what is the next step for 9.0 JDE users. If it is not true, what is the timing of the ESU's to be released so they can be applied.
Thank you!
