|
|
|
|
|
their deprecation cycle, and we've :ref:`begun the deprecation process for

* The cache keys used by :ttag:`cache` and generated by
|
|
|
|
|
:func:`~django.core.cache.utils.make_template_fragment_key` are different
|
|
|
|
|
from the keys generated by older versions of Django. After upgrading to
|
|
|
|
|
Django 3.1, the first request to any previously cached template fragment will
|
|
|
|
|
be a cache miss.
