Hi, Some refactoring of the Celery config is underway and as some of the options have changed between Celery 3 and 4 I have asked the question whether Celery 3 is still supported. Apparently it is not (https://github.com/celery/celery/issues/4258 <https://github.com/celery/celery/issues/4258>).
As Celery 3 is also 2 major releases behind I propose to set Celery 4.0 as a minimum supported version with Celery 4.1 being the recommend version. I think this is also important as we do see some intermittent issues with Celery that are reported to us but are, most likely, issues in Celery. I don’t want to take care of those as they are difficult to debug. I would like to do this per 1.9.0. The 1.8.X branch can still support Celery 3. Cheers Bolke
