I think it's worth including #20213

[alamb]

I am out next week so I can't realistically drive this release (though I can probably do the mechanics of tarball and voting)

Here is a backport of #20109

• [branch-52] FilterExec should remap indices of parent dynamic filters (#20286) #20347

After that, I think we are still waiting on

• Incorrect answers due to an incorrectly removed Sort before AggregateExec #20244

• REview / merge fix: Fix incorrect SortExec removal before AggregateExec (option 2) #20247

• Backport: TBD

• Dynamic filter applied to the wrong table when using subqueries #20213

• Fix: TBD

• Backport: TBD
