Ticket #35011, comment 1
v2 v3 9 9 The fundamental issue here is that the order of specified fields in `values` has never been a 1:1 match to the order of the `SELECT` columns but the latter is a necessity to do proper `UNION` between querysets. 10 10 11 The order is, and has always been, `SELECT *extra, *fields, *annotations` and within each groups the order of `values` is respected since #28553 which landed in d6b6e5d0fd4e6b6d0183b4cf6e4bd4f9afc7bf67 so I guess this is what broke things on your side during the attempted upgrade but that your tests failed to capture. In this sense I guess this could be considered a release blocker as it changed the ordering from an ambiguous ordering to the other.11 [https://github.com/django/django/blob/14884b6be89963c8ceb2c9da459ed8421aea3bf8/django/db/models/sql/compiler.py#L251-L276 The order is, and has always been], `SELECT *extra, *fields, *annotations` and within each groups the order of `values` is respected since #28553 which landed in d6b6e5d0fd4e6b6d0183b4cf6e4bd4f9afc7bf67 so I guess this is what broke things on your side during the attempted upgrade but that your tests failed to capture.

I'd like to find time to get this across the finish line during the holidays so I'll assign to me in the mean time.
