:version: 2.0.6
- :include_notes_from: unreleased_20
+ :released: March 13, 2023
+
+ .. change::
+ :tags: bug, sql, regression
+ :tickets: 9461
+
+ Fixed regression where the fix for :ticket:`8098`, which was released in
+ the 1.4 series and provided a layer of concurrency-safe checks for the
+ lambda SQL API, included additional fixes in the patch that failed to be
+ applied to the main branch. These additional fixes have been applied.
+
+ .. change::
+ :tags: bug, typing
+ :tickets: 9451
+
+ Fixed typing issue where :meth:`.ColumnElement.cast` did not allow a
+ :class:`.TypeEngine` argument independent of the type of the
+ :class:`.ColumnElement` itself, which is the purpose of
+ :meth:`.ColumnElement.cast`.
+
+ .. change::
+ :tags: bug, orm
+ :tickets: 9460
+
+ Fixed bug where the "active history" feature was not fully
+ implemented for composite attributes, making it impossible to receive
+ events that included the "old" value. This seems to have been the case
+ with older SQLAlchemy versions as well, where "active_history" would
+ be propagated to the underlying column-based attributes, but an event
+ handler listening to the composite attribute itself would not be given
+ the "old" value being replaced, even if the composite() were set up
+ with active_history=True.
+
+ Additionally, fixed a regression that's local to 2.0 which disallowed
+ active_history on composite from being assigned to the impl with
+ ``attr.impl.active_history=True``.
+
+
+ .. change::
+ :tags: bug, oracle
+ :tickets: 9459
+
+ Fixed reflection bug where Oracle "name normalize" would not work correctly
+ for reflection of symbols that are in the "PUBLIC" schema, such as
+ synonyms, meaning the PUBLIC name could not be indicated as lower case on
+ the Python side for the :paramref:`_schema.Table.schema` argument. Using
+ uppercase "PUBLIC" would work, but would then lead to awkward SQL queries
+ including a quoted ``"PUBLIC"`` name as well as indexing the table under
+ uppercase "PUBLIC", which was inconsistent.
+
+ .. change::
+ :tags: bug, typing
+
+ Fixed issues to allow typing tests to pass under Mypy 1.1.1.
+
+ .. change::
+ :tags: bug, sql
+ :tickets: 9440
+
+ Fixed regression where the :func:`_sql.select` construct would not be able
+ to render if it were given no columns and then used in the context of an
+ EXISTS, raising an internal exception instead. While an empty "SELECT" is
+ not typically valid SQL, in the context of EXISTS databases such as
+ PostgreSQL allow it, and in any case the condition now no longer raises
+ an internal exception.
+
+
+ .. change::
+ :tags: bug, orm
+ :tickets: 9418
+
+ Fixed regression involving pickling of Python rows between the cython and
+ pure Python implementations of :class:`.Row`, which occurred as part of
+ refactoring code for version 2.0 with typing. A particular constant were
+ turned into a string based ``Enum`` for the pure Python version of
+ :class:`.Row` whereas the cython version continued to use an integer
+ constant, leading to deserialization failures.
