:version: 2.0.11
- :include_notes_from: unreleased_20
+ :released: April 26, 2023
+
+ .. change::
+ :tags: bug, engine, regression
+ :tickets: 9682
+
+ Fixed regression which prevented the :attr:`_engine.URL.normalized_query`
+ attribute of :class:`_engine.URL` from functioning.
+
+ .. change::
+ :tags: bug, postgresql, regression
+ :tickets: 9701
+
+ Fixed critical regression caused by :ticket:`9618`, which modified the
+ architecture of the :term:`insertmanyvalues` feature for 2.0.10, which
+ caused floating point values to lose all decimal places when being inserted
+ using the insertmanyvalues feature with either the psycopg2 or psycopg
+ drivers.
+
+
+ .. change::
+ :tags: bug, mssql
+
+ Implemented the :class:`_sqltypes.Double` type for SQL Server, where it
+ will render ``DOUBLE PRECISION`` at DDL time. This is implemented using
+ a new MSSQL datatype :class:`_mssql.DOUBLE_PRECISION` which also may
+ be used directly.
+
+
+ .. change::
+ :tags: bug, oracle
+
+ Fixed issue in Oracle dialects where ``Decimal`` returning types such as
+ :class:`_sqltypes.Numeric` would return floating point values, rather than
+ ``Decimal`` objects, when these columns were used in the
+ :meth:`_dml.Insert.returning` clause to return INSERTed values.
+
+ .. change::
+ :tags: bug, orm
+ :tickets: 9583, 9595
+
+ Fixed 2.0 regression where use of :func:`_sql.bindparam()` inside of
+ :meth:`_dml.Insert.values` would fail to be interpreted correctly when
+ executing the :class:`_dml.Insert` statement using the ORM
+ :class:`_orm.Session`, due to the new
+ :ref:`ORM-enabled insert feature <orm_queryguide_bulk_insert>` not
+ implementing this use case.
+
+ .. change::
+ :tags: usecase, orm
+ :tickets: 9583, 9595
+
+ The :ref:`ORM bulk INSERT and UPDATE <orm_expression_update_delete>`
+ features now add these capabilities:
+
+ * The requirement that extra parameters aren't passed when using ORM
+ INSERT using the "orm" dml_strategy setting is lifted.
+ * The requirement that additional WHERE criteria is not passed when using
+ ORM UPDATE using the "bulk" dml_strategy setting is lifted. Note that
+ in this case, the check for expected row count is turned off.
+
+ .. change::
+ :tags: usecase, sql
+ :tickets: 8285
+
+ Added support for slice access with :class:`.ColumnCollection`, e.g.
+ ``table.c[0:5]``, ``subquery.c[:-1]`` etc. Slice access returns a sub
+ :class:`.ColumnCollection` in the same way as passing a tuple of keys. This
+ is a natural continuation of the key-tuple access added for :ticket:`8285`,
+ where it appears to be an oversight that the slice access use case was
+ omitted.
+
+ .. change::
+ :tags: bug, typing
+ :tickets: 9644
+
+ Improved typing of :class:`_engine.RowMapping` to indicate that it
+ support also :class:`_schema.Column` as index objects, not only
+ string names. Pull request courtesy Andy Freeland.
+
+ .. change::
+ :tags: engine, performance
+ :tickets: 9678, 9680
+
+ A series of performance enhancements to :class:`_engine.Row`:
+
+ * ``__getattr__`` performance of the row's "named tuple" interface has
+ been improved; within this change, the :class:`_engine.Row`
+ implementation has been streamlined, removing constructs and logic
+ that were specific to the 1.4 and prior series of SQLAlchemy.
+ As part of this change, the serialization format of :class:`_engine.Row`
+ has been modified slightly, however rows which were pickled with previous
+ SQLAlchemy 2.0 releases will be recognized within the new format.
+ Pull request courtesy J. Nick Koston.
+
+ * Improved row processing performance for "binary" datatypes by making the
+ "bytes" handler conditional on a per driver basis. As a result, the
+ "bytes" result handler has been removed for nearly all drivers other than
+ psycopg2, all of which in modern forms support returning Python "bytes"
+ directly. Pull request courtesy J. Nick Koston.
+
+ * Additional refactorings inside of :class:`_engine.Row` to improve
+ performance by Federico Caselli.
