- Added a new directive used within the scope of an attribute "set" operation

2014-02-01T00:57:38+00:00

to disable autoflush, in the case that the attribute needs to lazy-load
the "old" value, as in when replacing one-to-one values or some
kinds of many-to-one.  A flush at this point otherwise occurs
at the point that the attribute is None and can cause NULL violations.

- remove informix dialect, moved out to https://bitbucket.org/zzzeek/sqlalchemy_informixdb

2013-11-17T18:45:23+00:00

- remove informix, maxdb, access symbols from tests etc.

- merge ticket_1418 branch, [ticket:1418]

- The system of loader options has been entirely rearchitected to build
upon a much more comprehensive base, the :class:`.Load` object.  This
base allows any common loader option like :func:`.joinedload`,
:func:`.defer`, etc. to be used in a "chained" style for the purpose
of specifying options down a path, such as ``joinedload("foo").subqueryload("bar")``.
The new system supersedes the usage of dot-separated path names,
multiple attributes within options, and the usage of ``_all()`` options.
-  Added a new load option :func:`.orm.load_only`.  This allows a series
of column names to be specified as loading "only" those attributes,
deferring the rest.

Can set/change the "cascade" attribute on a :func:`.relationship`

construct after it's been constructed already.  This is not
a pattern for normal use but we like to change the setting
for demonstration purposes in tutorials.

the consideration of a pending object as

2013-01-25T02:31:23+00:00

an "orphan" has been modified to more closely match the
behavior as that of persistent objects, which is that the object
is expunged from the :class:`.Session` as soon as it is
de-associated from any of its orphan-enabled parents.  Previously,
the pending object would be expunged only if de-associated
from all of its orphan-enabled parents.  The new flag ``legacy_is_orphan``
is added to :func:`.orm.mapper` which re-establishes the
legacy behavior. [ticket:2655]

trying different approaches to test layout. in this one, the testing modules

become an externally usable package but still remains within the main sqlalchemy parent package.
in this system, we use kind of an ugly hack to get the noseplugin imported outside of the
"sqlalchemy" package, while still making it available within sqlalchemy for usage by
third party libraries.

- [feature] Adding/removing None from a mapped collection

2012-08-13T15:00:58+00:00

now generates attribute events.  Previously, a None
append would be ignored in some cases.  Related
to [ticket:2229].

- [feature] The presence of None in a mapped collection
now raises an error during flush.   Previously,
None values in collections would be silently ignored.
