do not allow non-cache-key entity objects in annotations

2023-04-30T18:53:31+00:00

Fixed critical caching issue where combination of :func:`_orm.aliased()`
:func:`_sql.case` and :func:`_hybrid.hybrid_property` expressions would
cause a cache key mismatch, leading to cache keys that held onto the actual
:func:`_orm.aliased` object while also not matching each other, filling up
the cache.

Fixes: #9728

dont assume _compile_options are present

2023-04-17T14:21:51+00:00

Fixed bug where various ORM-specific getters such as
:attr:`.ORMExecuteState.is_column_load`,
:attr:`.ORMExecuteState.is_relationship_load`,
:attr:`.ORMExecuteState.loader_strategy_path` etc. would throw an
``AttributeError`` if the SQL statement itself were a "compound select"
such as a UNION.

clarify get_isolation_level() excludes AUTOCOMMIT

2023-04-17T12:27:44+00:00

I thought this was documented but apparently not.

consider aliased mappers in cycles also

2023-04-02T18:27:58+00:00

Fixed endless loop which could occur when using "relationship to aliased
class" feature and also indicating a recursive eager loader such as
``lazy="selectinload"`` in the loader, in combination with another eager
loader on the opposite side. The check for cycles has been fixed to include
aliased class relationships.

Fixes: #9590

Version 1.4.48 placeholder

2023-03-18T17:09:08+00:00

implement content hashing for custom_op, not identity

2023-03-18T15:51:00+00:00

Fixed critical SQL caching issue where use of the :meth:`_sql.Operators.op`
custom operator function would not produce an appropriate cache key,
leading to reduce the effectiveness of the SQL cache.

Fixes: #9506

remove "listeners" docstring

2023-03-15T14:11:19+00:00

this should have been removed with #4638.

Add separate version notes for scalars

2023-02-27T13:18:41+00:00

Add separate 1.4.24 and 1.4.26 version notes for the .scalars method;
this covers Session, scoped_session, AsyncSession, async_scoped_session
as the "scoped" versions did not have the method added until 1.4.26
as part of :ticket:`7103`.

Also indicate scoped_session as ``sqlalchemy.orm.scoped_session`` in
docs rather than ``sqlalchemy.orm.scoping.scoped_session``.  This is
also happening in I77da54891860095edcb1f0625ead99fee89bd76f separately,
as both changesets refer to scoped_session without using ".scoping".

prevent float tests from running on asyncmy

2023-02-27T13:18:17+00:00

asyncmy 0.2.7 has had a loss in float precision for even
very low numbers of significant digits.
