:version: 1.3.20
- :include_notes_from: unreleased_13
+ :released: October 12, 2020
+
+ .. change::
+ :tags: bug, orm
+ :tickets: 4428
+
+ An :class:`.ArgumentError` with more detail is now raised if the target
+ parameter for :meth:`_query.Query.join` is set to an unmapped object.
+ Prior to this change a less detailed ``AttributeError`` was raised.
+ Pull request courtesy Ramon Williams.
+
+ .. change::
+ :tags: bug, mysql
+ :tickets: 5568
+
+ The "skip_locked" keyword used with ``with_for_update()`` will emit a
+ warning when used on MariaDB backends, and will then be ignored. This is
+ a deprecated behavior that will raise in SQLAlchemy 1.4, as an application
+ that requests "skip locked" is looking for a non-blocking operation which
+ is not available on those backends.
+
+
+
+ .. change::
+ :tags: bug, engine
+ :tickets: 5599
+
+ Fixed issue where a non-string object sent to
+ :class:`_exc.SQLAlchemyError` or a subclass, as occurs with some third
+ party dialects, would fail to stringify correctly. Pull request
+ courtesy Andrzej Bartosiński.
+
+ .. change::
+ :tags: bug, sql
+ :tickets: 5644
+
+ Fixed issue where the ``pickle.dumps()`` operation against
+ :class:`_expression.Over` construct would produce a recursion overflow.
+
+ .. change::
+ :tags: postgresql, usecase
+ :tickets: 4392
+
+ The psycopg2 dialect now support PostgreSQL multiple host connections, by
+ passing host/port combinations to the query string. Pull request courtesy
+ Ramon Williams.
+
+ .. seealso::
+
+ :ref:`psycopg2_multi_host`
+
+ .. change::
+ :tags: bug, mysql
+ :tickets: 5617
+
+ Fixed bug where an UPDATE statement against a JOIN using MySQL multi-table
+ format would fail to include the table prefix for the target table if the
+ statement had no WHERE clause, as only the WHERE clause were scanned to
+ detect a "multi table update" at that particular point. The target
+ is now also scanned if it's a JOIN to get the leftmost table as the
+ primary table and the additional entries as additional FROM entries.
+
+
+ .. change::
+ :tags: bug, postgresql
+ :tickets: 5518
+
+ Adjusted the :meth:`_types.ARRAY.Comparator.any` and
+ :meth:`_types.ARRAY.Comparator.all` methods to implement a straight "NOT"
+ operation for negation, rather than negating the comparison operator.
+
+ .. change::
+ :tags: bug, pool
+ :tickets: 5582
+
+ Fixed issue where the following pool parameters were not being propagated
+ to the new pool created when :meth:`_engine.Engine.dispose` were called:
+ ``pre_ping``, ``use_lifo``. Additionally the ``recycle`` and
+ ``reset_on_return`` parameter is now propagated for the
+ :class:`_engine.AssertionPool` class.
+
+ .. change::
+ :tags: bug, ext, associationproxy
+ :tickets: 5541, 5542
+
+ An informative error is now raised when attempting to use an association
+ proxy element as a plain column expression to be SELECTed from or used in a
+ SQL function; this use case is not currently supported.
+
+
+ .. change::
+ :tags: bug, sql
+ :tickets: 5618
+
+ Fixed bug where an error was not raised in the case where a
+ :func:`_sql.column` were added to more than one :func:`_sql.table` at a
+ time. This raised correctly for the :class:`_schema.Column` and
+ :class:`_schema.Table` objects. An :class:`_exc.ArgumentError` is now
+ raised when this occurs.
+
+ .. change::
+ :tags: bug, orm
+ :tickets: 4589
+
+ Fixed issue where using a loader option against a string attribute name
+ that is not actually a mapped attribute, such as a plain Python descriptor,
+ would raise an uninformative AttributeError; a descriptive error is now
+ raised.
+
+
+
+ .. change::
+ :tags: mysql, usecase
+ :tickets: 5462
+
+ Adjusted the MySQL dialect to correctly parenthesize functional index
+ expressions as accepted by MySQL 8. Pull request courtesy Ramon Williams.
+
+ .. change::
+ :tags: bug, engine
+ :tickets: 5632
+
+ Repaired a function-level import that was not using SQLAlchemy's standard
+ late-import system within the sqlalchemy.exc module.
+
+
+ .. change::
+ :tags: change, mysql
+ :tickets: 5539
+
+ Add new MySQL reserved words: ``cube``, ``lateral`` added in MySQL 8.0.1
+ and 8.0.14, respectively; this indicates that these terms will be quoted if
+ used as table or column identifier names.
+
+ .. change::
+ :tags: bug, mssql
+ :tickets: 5592
+
+ Fixed issue where a SQLAlchemy connection URI for Azure DW with
+ ``authentication=ActiveDirectoryIntegrated`` (and no username+password)
+ was not constructing the ODBC connection string in a way that was
+ acceptable to the Azure DW instance.
+
+ .. change::
+ :tags: bug, postgresql
+ :tickets: 5520
+
+ Fixed issue where the :class:`_postgresql.ENUM` type would not consult the
+ schema translate map when emitting a CREATE TYPE or DROP TYPE during the
+ test to see if the type exists or not. Additionally, repaired an issue
+ where if the same enum were encountered multiple times in a single DDL
+ sequence, the "check" query would run repeatedly rather than relying upon a
+ cached value.
+
+
+ .. change::
+ :tags: bug, tests
+ :tickets: 5635
+
+ Fixed incompatibilities in the test suite when running against Pytest 6.x.
