Currently we have:
1.8:
RemovedInDjango19Warning(DeprecationWarning) - Deprecations from 1.7
RemovedInDjango20Warning(PendingDeprecationWarning) - Deprecations from 1.8
master:
RemovedInDjango20Warning(DeprecationWarning) - Deprecations from 1.8
RemovedInDjango21Warning(PendingDeprecationWarning) - Deprecations from
master
In any case, implementing the new policy will require updating warnings from
master: RemovedInDjango21Warning needs to become either
RemovedInDjango22Warning or RemovedInDjango31Warning with the switch to SemVer.
The question is whether it's too invasive to update warnings in a 1.8 patch
release. If we ensure that RemovedInDjango19Warning remains importable by
aliasing it to RemovedInDjango20Warning(DeprecationWarning), I think it's
compatible enough not to delay implementing the scheme by another two years,
especially considering how warnings are normally used. But if we want to be
super cautious we could just leave the code as it is and document the problem
in the 1.8 release notes, after all we are extending the lifespan of the shims
(at least in appearance) which isn't as problematic as if we were shortening it.
