:version: 1.11.0
- :include_notes_from: unreleased
+ :released: May 15, 2023
+
+ .. change::
+ :tags: bug, batch
+ :tickets: 1237
+
+ Added placeholder classes for :class:`~.sqla.Computed` and
+ :class:`~.sqla.Identity` when older 1.x SQLAlchemy versions are in use,
+ namely prior to SQLAlchemy 1.3.11 when the :class:`~.sqla.Computed`
+ construct was introduced. Previously these were set to None, however this
+ could cause issues with certain codepaths that were using ``isinstance()``
+ such as one within "batch mode".
+
+ .. change::
+ :tags: bug, batch
+ :tickets: 1221
+
+ Correctly pass previously ignored arguments ``insert_before`` and
+ ``insert_after`` in ``batch_alter_column``
+
+ .. change::
+ :tags: change, py3k
+ :tickets: 1130
+
+ Argument signatures of Alembic operations now enforce keyword-only
+ arguments as passed as keyword and not positionally, such as
+ :paramref:`.Operations.create_table.schema`,
+ :paramref:`.Operations.add_column.type_`, etc.
+
+ .. change::
+ :tags: bug, postgresql
+ :tickets: 1230
+
+ Fix autogenerate issue with PostgreSQL :class:`.ExcludeConstraint`
+ that included sqlalchemy functions. The function text was previously
+ rendered as a plain string without surrounding with ``text()``.
+
+ .. change::
+ :tags: bug, mysql, regression
+ :tickets: 1240
+
+ Fixed regression caused by :ticket:`1166` released in version 1.10.0 which
+ caused MySQL unique constraints with multiple columns to not compare
+ correctly within autogenerate, due to different sorting rules on unique
+ constraints vs. indexes, which in MySQL are shared constructs.
+
+ .. change::
+ :tags: misc
+ :tickets: 1220
+
+ Update code snippets within docstrings to use ``black`` code formatting.

+
+ .. change::
+ :tags: bug, typing
+ :tickets: 1093
+
+ Updated stub generator script to also add stubs method definitions for the
+ :class:`.Operations` class and the :class:`.BatchOperations` class obtained
+ from :meth:`.Operations.batch_alter_table`. As part of this change, the
+ class hierarchy of :class:`.Operations` and :class:`.BatchOperations` has
+ been rearranged on top of a common base class :class:`.AbstractOperations`
+ in order to type correctly, as :class:`.BatchOperations` uses different
+ method signatures for operations than :class:`.Operations`.
+
+
+ .. change::
+ :tags: bug, typing
+
+ Repaired the return signatures for :class:`.Operations` that mostly
+ return ``None``, and were erroneously referring to ``Optional[Table]``
+ in many cases.
+
+ .. change::
+ :tags: usecase, commands
+ :tickets: 1109
+
+ Added quiet option to the command line, using the ``-q/--quiet``
+ option. This flag will prevent alembic from logging anything
+ to stdout.
+
+ .. change::
+ :tags: bug, autogenerate
+ :tickets: 1178
+
+ Modified the autogenerate implementation for comparing "server default"
+ values from user-defined metadata to not apply any quoting to the value
+ before comparing it to the server-reported default, except for within
+ dialect-specific routines as needed. This change will affect the format of
+ the server default as passed to the
+ :paramref:`.EnvironmentContext.configure.compare_server_default` hook, as
+ well as for third party dialects that implement a custom
+ ``compare_server_default`` hook in their alembic impl, to be passed "as is"
+ and not including additional quoting. Custom implementations which rely
+ on this quoting should adjust their approach based on observed formatting.
+
+ .. change::
+ :tags: bug, api, autogenerate
+ :tickets: 1235
+
+ Fixed issue where :func:`.autogenerate.render_python_code` function did not
+ provide a default value for the ``user_module_prefix`` variable, leading to
+ ``NoneType`` errors when autogenerate structures included user-defined
+ types. Added new parameter
+ :paramref:`.autogenerate.render_python_code.user_module_prefix` to allow
+ this to be set as well as to default to ``None``. Pull request courtesy
+ tangkikodo.
+
+
+ .. change::
+ :tags: usecase, asyncio
+ :tickets: 1231
+
+ Added :meth:`.AbstractOperations.run_async` to the operation module to
+ allow running async functions in the ``upgrade`` or ``downgrade`` migration
+ function when running alembic using an async dialect. This function will
+ receive as first argument an
+ :class:`~sqlalchemy.ext.asyncio.AsyncConnection` sharing the transaction
+ used in the migration context.
