To protect against BREACH attacks, the CSRF protection mechanism now changes the form token value on every request (while keeping an invariant secret which can be used to validate the different tokens).

File uploads don’t count toward this limit. DATA_UPLOAD_MAX_NUMBER_FIELDS limits the number of GET/POST parameters that are parsed. Applications that receive unusually large form posts may need to tune these settings.

Fixed a regression in 1.11.3 on Python 2 where non-ASCII format values for date/time widgets results in an empty value in the widget’s HTML (#28355). Fixed QuerySet.union() and difference() when combining with a queryset raising EmptyResultSet (#28378).

In Django 1.3, the get_initial method of the django.views.generic.edit.FormMixin class was returning the class initial dictionary.

The CSRF-protection system is based on a random nonce sent to the client in a cookie which must be sent by the client on future requests and, in forms, a hidden value which must be submitted back with the form.

Release notes Django 1.5 release notes Backwards incompatible changes in 1.5Changes in tests execution

This should not cause any problems unless you have existing doctests which assume a TransactionTestCase executed earlier left some database state behind or unit tests that rely on some form of state being preserved after the execution of other tests.

The CSRF-protection system is based on a random nonce sent to the client in a cookie which must be sent by the client on future requests and, in forms, a hidden value which must be submitted back with the form.

Release notes Django 1.6 release notes Features deprecated in 1.6

Previously, if you wanted a ModelForm to use all fields on the model, you could simply omit the Meta.fields attribute, and all fields would be used.

Release notes Django 1.6 release notes Features deprecated in 1.6

The generic views CreateView and UpdateView, and anything else derived from ModelFormMixin, are vulnerable to the security problem described in the section above, because they can automatically create a ModelForm that uses all fields for a model.

Release notes Django 1.6.3 release notes

The CSRF-protection system is based on a random nonce sent to the client in a cookie which must be sent by the client on future requests and, in forms, a hidden value which must be submitted back with the form.

If you relied on these methods to alter structures like form fields, you should now treat these OrderedDicts as immutable objects and override them to change their content.
