The https://github.com/apache/airflow/pull/53770 ("Migrated prod builds to use python built from source") has been merged. This means that our PROD images built from main (soon 3.1) will get the latest released Python packages directly from the PSF release server and we build Python from sources. This will give us more control over what is "in" the image and allow us to switch to the latestst Python patchlevel faster.
We still have lazy consensus running in https://lists.apache.org/thread/fp6j1jcx82bok75y087p0445bbl6rzsb, but I want to use the calmer weekend time to see and fix any teething problems. - we can always revert it if need be. We do not plan to back-port it to 3.0. For the next few hours, rebuilding the CI image might be slow because the Dockerfiles used trigger cache invalidation at the very start - but it should get back to faster builds soon. J
