These changes should be ported from 1.3 back to 1.0 or
possibly 0.9 to the extent they are relevant in each
version. In 1.3 we hope to turn all deprecation documentation
into warnings.

The mapping to B over a join defines an alternate primary key
based on all the primary key columns in the join unless we
re-define it explicitly. Similarly, people expect that
``.id`` looks the same. make sure these line up with the
old mapping.

Composites can behave in a "nested" fashion by defining the
class in that way. To make the constructor more convenient,
a callable can be passed to :func:`.composite` instead of the
class itself. This works now, so add a test to ensure this
pattern remains available.

Update documentation to include background on arbitrary superclass
usage, add full cross-linking between all related methods and parameters.
De-emphasize "twophase" and document that it is not well-supported
in drivers.

Include information about eager_defaults etc. These

we do now.

These docs were inaccurate and verbose, try to modernize them

MySQL dialects now query the server version using ``SELECT @@version``
explicitly to the server to ensure we are getting the correct version
information back. Proxy servers like MaxScale interfere with the value
that is passed to the DBAPI's connection.server_version value so this
is no longer reliable.

Repaired regression caused in 1.2.3 and 1.1.16 regarding association proxy
objects, revising the approach to 🎫`4185` when calculating the
"owning class" of an association proxy to default to choosing the current
class if the proxy object is not directly associated with a mapped class,
such as a mixin.

This section documents an aspect of the ORM that is
more generalized than just collections as well as more general
than just using session.delete(), even though session.delete()
with collections is the most common use case. Try to expand
out the scope here to explain the situation from the perspective
of any kind of relationship, include example with delete cascade
with many-to-one as well.

Fixed issue in post_update feature where an UPDATE is emitted
when the parent object has been deleted but the dependent object
is not. This issue has existed for a long time however
since 1.2 now asserts rows matched for post_update, this
was raising an error.

(cherry picked from commit 8607ae51fc)
Fixed regression caused by fix for issue 🎫`4116` affecting versions
1.2.2 as well as 1.1.15, which had the effect of mis-calculation of the
"owning class" of an :class:`.AssociationProxy` as the ``NoneType`` class
in some declarative mixin/inheritance situations as well as if the
association proxy were accessed off of an un-mapped class. The "figure out
the owner" logic has been replaced by an in-depth routine that searches
through the complete mapper hierarchy assigned to the class or subclass to
determine the correct (we hope) match; will not assign the owner if no
match is found. An exception is now raised if the proxy is used
against an un-mapped instance.

(cherry picked from commit 650b9eddae)
Fixed a fairly serious connection pool bug where a connection that is
acquired after being refreshed as a result of a user-defined
:class:`.DisconnectionError` or due to the 1.2-released "pre_ping" feature
would not be correctly reset if the connection were returned to the pool by
weakref cleanup (e.g. the front-facing object is garbage collected); the
weakref would still refer to the previously invalidated DBAPI connection
which would have the reset operation erroneously called upon it instead.
This would lead to stack traces in the logs and a connection being checked
into the pool without being reset, which can cause locking issues.

with op().
Not sure if this can be further improved at some point, such
as if a BinaryExpression automatically applied self_group()
when op() is called, however for the moment op() behaves consistently
as with all other operators without any ad-hoc effects.
