- reword and update documentation on passive_updates=False; as virtually

2015-08-27T19:56:00+00:00

all DBs now support ON UPDATE CASCADE other than Oracle, there's no need
to try to reimplement more functionality here and users should be encouraged
to forego natural PKs unless their target platform supports them.

Fix typo in 'Relationships API' docs

- Fixed more regressions caused by NEVER_SET; comparisons

2015-04-20T21:38:03+00:00

to transient objects with attributes unset would leak NEVER_SET,
and negated_contains_or_equals would do so for any transient
object as the comparison used only the committed value.
Repaired the NEVER_SET cases, fixes #3371, and also made
negated_contains_or_equals() use state_attr_by_column() just
like a non-negated comparison, fixes #3374

- Made a small improvement to the heuristics of relationship when

determining remote side with semi-self-referential (e.g. two joined
inh subclasses referring to each other), non-simple join conditions
such that the parententity is taken into account and can reduce the
need for using the ``remote()`` annotation; this can restore some
cases that might have worked without the annotation prior to 0.9.4
via :ticket:`2948`. fixes #3364

- Added a new extension suite :mod:`sqlalchemy.ext.baked`. This

simple but unusual system allows for a dramatic savings in Python
overhead for the construction and processing of orm :class:`.Query`
objects, from query construction up through rendering of a string
SQL statement.

- Fixed bugs in ORM object comparisons where comparison of

2015-02-20T20:14:08+00:00

many-to-one ``!= None`` would fail if the source were an aliased
class, or if the query needed to apply special aliasing to the
expression due to aliased joins or polymorphic querying; also fixed
bug in the case where comparing a many-to-one to an object state
would fail if the query needed to apply special aliasing
due to aliased joins or polymorphic querying.
fixes #3310

- Fixed bug in lazy loading SQL construction whereby a complex

2015-02-03T00:46:13+00:00

primaryjoin that referred to the same "local" column multiple
times in the "column that points to itself" style of self-referential
join would not be substituted in all cases.   The logic to determine
substitutions here has been reworked to be more open-ended.
fixes #3300

- add MemoizedSlots, a generalized solution to using getattr

2015-01-06T00:02:08+00:00

for memoization on a class that uses slots.
- apply many more __slots__.  mem use for nova now at 46% savings

- fix links for loading, add a redirect page
