Interesting...and I thoguht 22000.65 would be the "latest"...but 71 ? And 22141.1000 does indeed sound like far in the future...
22000.x will probably move to Beta channel until GA for October while work and testing happen on co_refresh for next year.
Yes, that's what I expect and makes sense. 22000.x will move to beta this month/maybe next month. DEV will continue BAU, but now on 22*** that eventually will become 23000 for 2022 release.
