Not sure what is the "current version"? Auto-Park is not actually FSDS code or at least a part of FSDS. It seems all versions of 24.14.x to 24.20.x have the same Auto-Park now. In fact I stated and posted video proof of getting the faster Auto-Park a few days before the 24.14.9 update. So it seems to be more of an invisible Delta update sent.
Also as to the faster. Yesterday I used Auto-Park and pulled up so it had to make a couple of adjustments. It switched from R to D to R so fast it kinda whipped my head a little forward and back.
It also seems that it is getting faster at switching gears by the week.
