Fixed #22983: Alert when squashing RunPython operations with referred functions.
Bump the default iterations for PBKDF2.

The rate at which we've increased this has not been keeping up with hardware (and software) improvements, and we're now considerably behind where we should be. The delta between our performance and an optimized implementation's performance prevents us from improving that further, but hopefully once Python 2.7.8 and 3.4+ get into more hands we can more aggressively increase this number.
Removed extra newline.
Checked more precisely whether the app registry is ready.

Accounted for the three stages of population: app configs, models,
ready() methods of app configs.
Fixed #22939 -- Delayed admin_static backend detection

Thanks generalov for the report.
Added a newline to appease flake8
Fixed #23015 -- Fixed major/minor release terminology in docs.
Fixed/improved release note for refs #13147; thanks Loic.
Fixed #22789 -- Deprecated django.contrib.webdesign.

Moved the {% lorem %} tag to built-in tags.
Fixed #22994 -- regression with generic FK + admin list_view

The reason for the regression was that the GenericForeignKey field isn't
something meta.get_field_by_name() should return. The reason is that a
couple of places in Django expects get_field_by_name() to work this way.
It could make sense to return GFKs from get_field_by_name(), but that
should likely be done as part of meta refactoring or virtual fields
refactoring patches.

Thanks to glicerinu@gmail.com for the report and to Tim for working on
the issue.
Fixed #22992 -- regression in .filter(generic_fk=...) error message

Generic Foreign Keys can't be used as lhs in lookups for historical
reasons. Django 1.6 gave a FieldDoesNotExist exception when using GFKs
as lhs in lookups, but due to regression caused by lookup refactor patch
(20bab2cf9d02a5c6477d8aac066a635986e0d3f3) the exception type was
changed to AttributeError.

It might be a good idea to add support for gfk__exact and gfk__in lookups
later on.

Thanks to glicerinu@gmail.com for the report. The code in this commit
was written by Tim Graham.
Fixed #22791 -- Invoke interactive questioner only for conflicts in specified apps.

This fixes the Chinese language issues described in #23005 but
also provides for other fallback exceptions by updating the
LANG_INFO structure.
Thanks caxekis at gmail.com for the report and Tim Graham for the
review.

Thanks lorinkoz at gmail.com for the report, Collin Anderson

Further fix the release notes for refs #13147.
