Segment Rates for 2022 Cash Balance Contributions

I have a client who is terminating their Cash Balance Plan and wants to make their 2022 contributions based on the short plan year, so they can get the money paid out before the end of the year.

Have the '22 segment rates been released as of yet?  If not, is it OK to use the '21 rates?

Thanks!
