* Geometries now allow list-like manipulation, e.g., can add, insert, delete vertexes (or other geometries in collections) like Python lists. Thanks, Aryeh Leib Taurog.
* Added support for GEOS prepared geometries via `prepared` property. Prepared geometries significantly speed up certain operations.
* Added support for GEOS cascaded union as `MultiPolygon.cascaded_union` property.
* Added support for GEOS line merge as `merged` property on `LineString`, and `MultiLineString` geometries. Thanks, Paul Smith.
* No longer use the deprecated C API for serialization to/from WKB and WKT. Now use the GEOS I/O classes, which are now exposed as `WKTReader`, `WKTWriter`, `WKBReader`, and `WKBWriter` (which supports 3D and SRID inclusion)
* Moved each type of geometry to their own module, eliminating the cluttered `geometries.py`.
* Internally, all C API methods are explicitly called from a module rather than a star import.

Most of the hard work for this was done by akaihola.
There are still possibly some problems with the i18n template tags,
since they are written quite differently and a few other bug fixes have
to made before they can be fixed.

Some template filters and tags understood single-quoted arguments, others
didn't. This makes everything consistent. Based on a patch from akaihola.

The conditional processing decorator from r10114 wasn't parsing ETags

This provides support for views that can have their ETag and/or Last-modified
values computed much more quickly than the view itself. Supports all HTTP
verbs (not just GET).
Documentation and tests need a little more fleshing out (I'm not happy with the
documentation at the moment, since it's a bit backwards), but the functionality
is correct.

Previously on "things we changed in the recent past".... the database
connection setup was changed. People were happy. Except for those
running on Python 2.3.
We had completely broken Django on Python 2.3. Turns out, this is due to
a long-standing bug in the _threading_local module that interacts with
object creation in 2.3.
Interestingly, although the bug remains in Python 2.4 and 2.5, they
don't trip over it for reasons I don't entirely understand at the
moment.

In extreme cases, some fields are expensive to load from the database

Affects the postgresql_psycopg2 backend only. We now don't use the
"RETURNING" syntax in SQL INSERT statements unless it's required by the
autocommit behaviour. This fixes an edge-case that could cause crashes
with earlier PostgreSQL versions, but the broader problem remains to be
fixed (which is #10509).
Fixed#10467. Refs #10509.

We can't use the default manager in Model.save_base(), since we need to
retrieve existing objects which might be filtered out by that manager. We now
always use a plain Manager instance at that point (or something that can
replace it, such as a GeoManager), making all existing rows in the
database visible to the saving code.
The logic for detecting a "suitable replacement" plain base is the same as for
related fields: if the use_for_related_fields is set on the manager subclass,
we can use it. The general requirement here is that we want a base class that
returns the appropriate QuerySet subclass, but does not restrict the rows
returned.
Fixed#8990, #9527.
Refs #2698 (which is not fixed by this change, but it's the first part of a
larger change to fix that bug.)

In order to report more comphrehensible tracebacks, remove the super()
constructor call, since passing args to object.__init__ ends badly. So some
subclassing possibilities are now removed, but it's the "dummy" backend, so
we can make some compromises.

I introduced a bad regression in r10029, forgetting to check that some
syntax was supported. For now, you can't use autocommit=True with 8.1

get the SQL regression for the default path out of the code right now.

Ensure to read the documentation before blindly enabling this: requires some

This is backwards-compatible but will likely break third-party database backends. Specific API changes are:
* BaseDatabaseWrapper.__init__() now takes a settings_dict instead of a settings module. It's called settings_dict to disambiguate, and for easy grepability. This should be a dictionary containing DATABASE_NAME, etc.
* BaseDatabaseWrapper has a settings_dict attribute instead of an options attribute. BaseDatabaseWrapper.options is now BaseDatabaseWrapper['DATABASE_OPTIONS']
* BaseDatabaseWrapper._cursor() no longer takes a settings argument.
* BaseDatabaseClient.__init__() now takes a connection argument (a DatabaseWrapper instance) instead of no arguments.

Adding a get_db_prep_save() call to the UpdateQuery code path meant it
was being called twice if you updated an existing model attribute. This
change removes that double call and also makes TimeField.to_python() a
little more robust for the benefit of the Oracle backend (just in case).

Previously, you could explicitly assign None to a non-null ForeignKey
(or other) field when creating the model (Child(parent=None), etc). We
now throw an exception when you do that, which matches the behaviour
when you assign None to the attribute after creation.

This includes a fairly large refactor of the update() query path (and
the initial portions of constructing the SQL for any query). The
previous code appears to have been only working more or less by accident
and was very fragile.

If an update only affected an ancestor model (not the child), we were
returning 0 for the number of rows updated. This could have been
misleading if the value is used to detect an update occuring. So we now
return the rowcount from the first non-trivial query that is executed
(if any). Still a slight compromise, but better than what we had.

This permits running Django's core tests under an alternative test runner. Most

In r9707 we added a preference to use Python's standard json module (Python 2.6

This avoids the problem of, for example, saving a change to the Site model in
the admin interface and then seeing the wrong instanec returned in the next
call to get_current_site().
It's still possible to end up with an inconsistent cache if update() is used to
change the Site model, but that's pretty unavoidable. It's also a slightly odd
way to update a Site model, so if you really need to do that, you can manage to
call SiteManager.clear() at the same time.
