-Fixed bug where Postgresql JSON type was not able to persist or
otherwise render a SQL NULL column value, rather than a JSON-encoded
``'null'``. To support this case, changes are as follows:
* The value :func:`.null` can now be specified, which will always
result in a NULL value resulting in the statement.
* A new parameter :paramref:`.JSON.none_as_null` is added, which
when True indicates that the Python ``None`` value should be
peristed as SQL NULL, rather than JSON-encoded ``'null'``.
Retrival of NULL as None is also repaired for DBAPIs other than
psycopg2, namely pg8000.

- The MySQL dialect will now disable :meth:`.ConnectionEvents.handle_error`
events from firing for those statements which it uses internally
to detect if a table exists or not. This is achieved using an
execution option ``skip_user_error_events`` that disables the handle
error event for the scope of that execution. In this way, user code
that rewrites exceptions doesn't need to worry about the MySQL
dialect or other dialects that occasionally need to catch
SQLAlchemy specific exceptions.

clause with the given alias name, where the column itself is
anonymously named.

- Fixed a regression caused by :ticket:`2976` released in 0.9.4 where
the "outer join" propagation along a chain of joined eager loads
would incorrectly convert an "inner join" along a sibling join path
into an outer join as well, when only descendant paths should be
receiving the "outer join" propagation; additionally, fixed related
issue where "nested" join propagation would take place inappropriately
between two sibling join paths.
this is accomplished by re-introducing the removed flag "allow_innerjoin",
now inverted and named "chained_from_outerjoin". Propagating this flag
allows us to know when we have encountered an outerjoin along a load
path, without confusing it for state obtained from a sibling path.
