In #21430 (https://github.com/django/django/commit/42736ac), unpickling
has been changed to log a warning for incompatible versions. While this
raises awareness, this is not really practical if you have lots of
deployments to consider.
We are using mostly automated deployments to quickly provide the latest
changes to our customers. Whenever we update to a newer Django, we need to
clear the whole cache. Automating this requires special handling, as
running the cache invalidation on every deployment seems to be overkill
for unrelated updates - thus some custom logic is required to only force
an invalidation on Django package changes when necessary at the moment.
For this reason, I would like to propose an additional/changed solution
which turns this into hard failures which can be handled by my application
without having to invalidate the cache itself. This way, I am able to
cleanly detect this and handle it appropriately.
Due to being a backwards-incompatible change, this might be changed by a
new setting which defaults to the old behavior.
