Thanks Eli Collins for the report and the patch.

Applied the rule that string encoding should happen as late as
possible. This is also a preparation for Python 3 compatibility.

Thanks Will Hardy for the report and the patch.

This is a good practice for accessibility.
Thanks Jessica McKellar for the report.

When constructing a polygon with Polygon.from_bbox, do not convert
parameters to strings at this stage (str defaults to 12 significant
digits).

Django Admin's input for BigIntegerField should be larger, Fixes #17804 

Both false positives and false negatives of HttpRequest.is_secure can be
dangerous.

Docs: "Form in a view" example doesn't use RequestContext

Fixed #17138 -- Removed the 'summary' attribute from the admin index tables to be html5-valid.

In previous version it used /django/forms/ which was fragile - for some
users .pyc files were not generated and this tests failed.

In the discussion here: https://code.djangoproject.com/ticket/17138
it was decided that using the caption for this previously
non-visible part of the table element was not semantic, so in this
patch is moves that summary to the `title` attribute of the `a`
tag which when overed over, on most browsers, will show the text.

self.settings_override from test subclasses were overwriting parent
attribute.

When using the template system in standalone mode and if the url
template tag is used, ROOT_URLCONF has to be defined.
Thanks techtonik for the report.

Implemented this by adding a stealth table_name_filter option for the
command.

Fixed #18409 -- Made RegexField work with unicode characters.

Resolves Flatpages test issues by:
 - Creating an example_site fixture
 - Overriding project SITE_ID setting to 1
 - Normalizing the use of the hardcoded (1) site_id to settings.SITE_ID

When generating error message in to_python, any unicode string
containing non-ascii characters triggered a UnicodeEncodeError for
most field types.

gzip.GzipFile does not support files with mode set to None.

Fixed #18393 -- Prevented blocktrans to crash when a variable name is badly formatted.
