Scheduled weekly dependency update for week 44

[pyup-bot]

Update Flask from 1.1.2 to 3.0.3.

Changelog

3.0.3

-------------

Released 2024-04-07

-   The default ``hashlib.sha1`` may not be available in FIPS builds. Don't
 access it at import time so the developer has time to change the default.
 :issue:`5448`
-   Don't initialize the ``cli`` attribute in the sansio scaffold, but rather in
 the ``Flask`` concrete class. :pr:`5270`

3.0.2

-------------

Released 2024-02-03

-   Correct type for ``jinja_loader`` property. :issue:`5388`
-   Fix error with ``--extra-files`` and ``--exclude-patterns`` CLI options.
 :issue:`5391`

3.0.1

-------------

Released 2024-01-18

-   Correct type for ``path`` argument to ``send_file``. :issue:`5230`
-   Fix a typo in an error message for the ``flask run --key`` option. :pr:`5344`
-   Session data is untagged without relying on the built-in ``json.loads``
 ``object_hook``. This allows other JSON providers that don't implement that.
 :issue:`5381`
-   Address more type findings when using mypy strict mode. :pr:`5383`

3.0.0

-------------

Released 2023-09-30

-   Deprecate the ``__version__`` attribute. Use feature detection, or
 ``importlib.metadata.version("flask")``, instead. :issue:`5230`
-   Restructure the code such that the Flask (app) and Blueprint
 classes have Sans-IO bases. :pr:`5127`
-   Allow self as an argument to url_for. :pr:`5264`

-   Remove previously deprecated code. :pr:`4995`

 -   The ``push`` and ``pop`` methods of the deprecated ``_app_ctx_stack`` and
     ``_request_ctx_stack`` objects are removed. ``top`` still exists to give
     extensions more time to update, but it will be removed.
 -   The ``FLASK_ENV`` environment variable, ``ENV`` config key, and ``app.env``
     property are removed.
 -   The ``session_cookie_name``, ``send_file_max_age_default``, ``use_x_sendfile``,
     ``propagate_exceptions``, and ``templates_auto_reload`` properties on ``app``
     are removed.
 -   The ``JSON_AS_ASCII``, ``JSON_SORT_KEYS``, ``JSONIFY_MIMETYPE``, and
     ``JSONIFY_PRETTYPRINT_REGULAR`` config keys are removed.
 -   The ``app.before_first_request`` and ``bp.before_app_first_request`` decorators
     are removed.
 -   ``json_encoder`` and ``json_decoder`` attributes on app and blueprint, and the
     corresponding ``json.JSONEncoder`` and ``JSONDecoder`` classes, are removed.
 -   The ``json.htmlsafe_dumps`` and ``htmlsafe_dump`` functions are removed.
 -   Calling setup methods on blueprints after registration is an error instead of a
     warning. :pr:`4997`

-   Importing ``escape`` and ``Markup`` from ``flask`` is deprecated. Import them
 directly from ``markupsafe`` instead. :pr:`4996`
-   The ``app.got_first_request`` property is deprecated. :pr:`4997`
-   The ``locked_cached_property`` decorator is deprecated. Use a lock inside the
 decorated function if locking is needed. :issue:`4993`
-   Signals are always available. ``blinker>=1.6.2`` is a required dependency. The
 ``signals_available`` attribute is deprecated. :issue:`5056`
-   Signals support ``async`` subscriber functions. :pr:`5049`
-   Remove uses of locks that could cause requests to block each other very briefly.
 :issue:`4993`
-   Use modern packaging metadata with ``pyproject.toml`` instead of ``setup.cfg``.
 :pr:`4947`
-   Ensure subdomains are applied with nested blueprints. :issue:`4834`
-   ``config.from_file`` can use ``text=False`` to indicate that the parser wants a
 binary file instead. :issue:`4989`
-   If a blueprint is created with an empty name it raises a ``ValueError``.
 :issue:`5010`
-   ``SESSION_COOKIE_DOMAIN`` does not fall back to ``SERVER_NAME``. The default is not
 to set the domain, which modern browsers interpret as an exact match rather than
 a subdomain match. Warnings about ``localhost`` and IP addresses are also removed.
 :issue:`5051`
-   The ``routes`` command shows each rule's ``subdomain`` or ``host`` when domain
 matching is in use. :issue:`5004`
-   Use postponed evaluation of annotations. :pr:`5071`

2.2.5

-------------

Released 2023-05-02

-   Update for compatibility with Werkzeug 2.3.3.
-   Set ``Vary: Cookie`` header when the session is accessed, modified, or refreshed.

2.2.4

-------------

Released 2023-04-25

-   Update for compatibility with Werkzeug 2.3.

2.2.3

-------------

Released 2023-02-15

-   Autoescape is enabled by default for ``.svg`` template files. :issue:`4831`
-   Fix the type of ``template_folder`` to accept ``pathlib.Path``. :issue:`4892`
-   Add ``--debug`` option to the ``flask run`` command. :issue:`4777`

2.2.2

-------------

Released 2022-08-08

-   Update Werkzeug dependency to >= 2.2.2. This includes fixes related
 to the new faster router, header parsing, and the development
 server. :pr:`4754`
-   Fix the default value for ``app.env`` to be ``"production"``. This
 attribute remains deprecated. :issue:`4740`

2.2.1

-------------

Released 2022-08-03

-   Setting or accessing ``json_encoder`` or ``json_decoder`` raises a
 deprecation warning. :issue:`4732`

2.2.0

-------------

Released 2022-08-01

-   Remove previously deprecated code. :pr:`4667`

 -   Old names for some ``send_file`` parameters have been removed.
     ``download_name`` replaces ``attachment_filename``, ``max_age``
     replaces ``cache_timeout``, and ``etag`` replaces ``add_etags``.
     Additionally, ``path`` replaces ``filename`` in
     ``send_from_directory``.
 -   The ``RequestContext.g`` property returning ``AppContext.g`` is
     removed.

-   Update Werkzeug dependency to >= 2.2.
-   The app and request contexts are managed using Python context vars
 directly rather than Werkzeug's ``LocalStack``. This should result
 in better performance and memory use. :pr:`4682`

 -   Extension maintainers, be aware that ``_app_ctx_stack.top``
     and ``_request_ctx_stack.top`` are deprecated. Store data on
     ``g`` instead using a unique prefix, like
     ``g._extension_name_attr``.

-   The ``FLASK_ENV`` environment variable and ``app.env`` attribute are
 deprecated, removing the distinction between development and debug
 mode. Debug mode should be controlled directly using the ``--debug``
 option or ``app.run(debug=True)``. :issue:`4714`
-   Some attributes that proxied config keys on ``app`` are deprecated:
 ``session_cookie_name``, ``send_file_max_age_default``,
 ``use_x_sendfile``, ``propagate_exceptions``, and
 ``templates_auto_reload``. Use the relevant config keys instead.
 :issue:`4716`
-   Add new customization points to the ``Flask`` app object for many
 previously global behaviors.

 -   ``flask.url_for`` will call ``app.url_for``. :issue:`4568`
 -   ``flask.abort`` will call ``app.aborter``.
     ``Flask.aborter_class`` and ``Flask.make_aborter`` can be used
     to customize this aborter. :issue:`4567`
 -   ``flask.redirect`` will call ``app.redirect``. :issue:`4569`
 -   ``flask.json`` is an instance of ``JSONProvider``. A different
     provider can be set to use a different JSON library.
     ``flask.jsonify`` will call ``app.json.response``, other
     functions in ``flask.json`` will call corresponding functions in
     ``app.json``. :pr:`4692`

-   JSON configuration is moved to attributes on the default
 ``app.json`` provider. ``JSON_AS_ASCII``, ``JSON_SORT_KEYS``,
 ``JSONIFY_MIMETYPE``, and ``JSONIFY_PRETTYPRINT_REGULAR`` are
 deprecated. :pr:`4692`
-   Setting custom ``json_encoder`` and ``json_decoder`` classes on the
 app or a blueprint, and the corresponding ``json.JSONEncoder`` and
 ``JSONDecoder`` classes, are deprecated. JSON behavior can now be
 overridden using the ``app.json`` provider interface. :pr:`4692`
-   ``json.htmlsafe_dumps`` and ``json.htmlsafe_dump`` are deprecated,
 the function is built-in to Jinja now. :pr:`4692`
-   Refactor ``register_error_handler`` to consolidate error checking.
 Rewrite some error messages to be more consistent. :issue:`4559`
-   Use Blueprint decorators and functions intended for setup after
 registering the blueprint will show a warning. In the next version,
 this will become an error just like the application setup methods.
 :issue:`4571`
-   ``before_first_request`` is deprecated. Run setup code when creating
 the application instead. :issue:`4605`
-   Added the ``View.init_every_request`` class attribute. If a view
 subclass sets this to ``False``, the view will not create a new
 instance on every request. :issue:`2520`.
-   A ``flask.cli.FlaskGroup`` Click group can be nested as a
 sub-command in a custom CLI. :issue:`3263`
-   Add ``--app`` and ``--debug`` options to the ``flask`` CLI, instead
 of requiring that they are set through environment variables.
 :issue:`2836`
-   Add ``--env-file`` option to the ``flask`` CLI. This allows
 specifying a dotenv file to load in addition to ``.env`` and
 ``.flaskenv``. :issue:`3108`
-   It is no longer required to decorate custom CLI commands on
 ``app.cli`` or ``blueprint.cli`` with ``with_appcontext``, an app
 context will already be active at that point. :issue:`2410`
-   ``SessionInterface.get_expiration_time`` uses a timezone-aware
 value. :pr:`4645`
-   View functions can return generators directly instead of wrapping
 them in a ``Response``. :pr:`4629`
-   Add ``stream_template`` and ``stream_template_string`` functions to
 render a template as a stream of pieces. :pr:`4629`
-   A new implementation of context preservation during debugging and
 testing. :pr:`4666`

 -   ``request``, ``g``, and other context-locals point to the
     correct data when running code in the interactive debugger
     console. :issue:`2836`
 -   Teardown functions are always run at the end of the request,
     even if the context is preserved. They are also run after the
     preserved context is popped.
 -   ``stream_with_context`` preserves context separately from a
     ``with client`` block. It will be cleaned up when
     ``response.get_data()`` or ``response.close()`` is called.

-   Allow returning a list from a view function, to convert it to a
 JSON response like a dict is. :issue:`4672`
-   When type checking, allow ``TypedDict`` to be returned from view
 functions. :pr:`4695`
-   Remove the ``--eager-loading/--lazy-loading`` options from the
 ``flask run`` command. The app is always eager loaded the first
 time, then lazily loaded in the reloader. The reloader always prints
 errors immediately but continues serving. Remove the internal
 ``DispatchingApp`` middleware used by the previous implementation.
 :issue:`4715`

2.1.3

-------------

Released 2022-07-13

-   Inline some optional imports that are only used for certain CLI
 commands. :pr:`4606`
-   Relax type annotation for ``after_request`` functions. :issue:`4600`
-   ``instance_path`` for namespace packages uses the path closest to
 the imported submodule. :issue:`4610`
-   Clearer error message when ``render_template`` and
 ``render_template_string`` are used outside an application context.
 :pr:`4693`

2.1.2

-------------

Released 2022-04-28

-   Fix type annotation for ``json.loads``, it accepts str or bytes.
 :issue:`4519`
-   The ``--cert`` and ``--key`` options on ``flask run`` can be given
 in either order. :issue:`4459`

2.1.1

-------------

Released on 2022-03-30

-   Set the minimum required version of importlib_metadata to 3.6.0,
 which is required on Python < 3.10. :issue:`4502`

2.1.0

-------------

Released 2022-03-28

-   Drop support for Python 3.6. :pr:`4335`
-   Update Click dependency to >= 8.0. :pr:`4008`
-   Remove previously deprecated code. :pr:`4337`

 -   The CLI does not pass ``script_info`` to app factory functions.
 -   ``config.from_json`` is replaced by
     ``config.from_file(name, load=json.load)``.
 -   ``json`` functions no longer take an ``encoding`` parameter.
 -   ``safe_join`` is removed, use ``werkzeug.utils.safe_join``
     instead.
 -   ``total_seconds`` is removed, use ``timedelta.total_seconds``
     instead.
 -   The same blueprint cannot be registered with the same name. Use
     ``name=`` when registering to specify a unique name.
 -   The test client's ``as_tuple`` parameter is removed. Use
     ``response.request.environ`` instead. :pr:`4417`

-   Some parameters in ``send_file`` and ``send_from_directory`` were
 renamed in 2.0. The deprecation period for the old names is extended
 to 2.2. Be sure to test with deprecation warnings visible.

 -   ``attachment_filename`` is renamed to ``download_name``.
 -   ``cache_timeout`` is renamed to ``max_age``.
 -   ``add_etags`` is renamed to ``etag``.

-   The ``RequestContext.g`` property is deprecated. Use ``g`` directly
 or ``AppContext.g`` instead. :issue:`3898`
-   ``copy_current_request_context`` can decorate async functions.
 :pr:`4303`
-   The CLI uses ``importlib.metadata`` instead of ``pkg_resources`` to
 load command entry points. :issue:`4419`
-   Overriding ``FlaskClient.open`` will not cause an error on redirect.
 :issue:`3396`
-   Add an ``--exclude-patterns`` option to the ``flask run`` CLI
 command to specify patterns that will be ignored by the reloader.
 :issue:`4188`
-   When using lazy loading (the default with the debugger), the Click
 context from the ``flask run`` command remains available in the
 loader thread. :issue:`4460`
-   Deleting the session cookie uses the ``httponly`` flag.
 :issue:`4485`
-   Relax typing for ``errorhandler`` to allow the user to use more
 precise types and decorate the same function multiple times.
 :issue:`4095, 4295, 4297`
-   Fix typing for ``__exit__`` methods for better compatibility with
 ``ExitStack``. :issue:`4474`
-   From Werkzeug, for redirect responses the ``Location`` header URL
 will remain relative, and exclude the scheme and domain, by default.
 :pr:`4496`
-   Add ``Config.from_prefixed_env()`` to load config values from
 environment variables that start with ``FLASK_`` or another prefix.
 This parses values as JSON by default, and allows setting keys in
 nested dicts. :pr:`4479`

2.0.3

-------------

Released 2022-02-14

-   The test client's ``as_tuple`` parameter is deprecated and will be
 removed in Werkzeug 2.1. It is now also deprecated in Flask, to be
 removed in Flask 2.1, while remaining compatible with both in
 2.0.x. Use ``response.request.environ`` instead. :pr:`4341`
-   Fix type annotation for ``errorhandler`` decorator. :issue:`4295`
-   Revert a change to the CLI that caused it to hide ``ImportError``
 tracebacks when importing the application. :issue:`4307`
-   ``app.json_encoder`` and ``json_decoder`` are only passed to
 ``dumps`` and ``loads`` if they have custom behavior. This improves
 performance, mainly on PyPy. :issue:`4349`
-   Clearer error message when ``after_this_request`` is used outside a
 request context. :issue:`4333`

2.0.2

-------------

Released 2021-10-04

-   Fix type annotation for ``teardown_*`` methods. :issue:`4093`
-   Fix type annotation for ``before_request`` and ``before_app_request``
 decorators. :issue:`4104`
-   Fixed the issue where typing requires template global
 decorators to accept functions with no arguments. :issue:`4098`
-   Support View and MethodView instances with async handlers. :issue:`4112`
-   Enhance typing of ``app.errorhandler`` decorator. :issue:`4095`
-   Fix registering a blueprint twice with differing names. :issue:`4124`
-   Fix the type of ``static_folder`` to accept ``pathlib.Path``.
 :issue:`4150`
-   ``jsonify`` handles ``decimal.Decimal`` by encoding to ``str``.
 :issue:`4157`
-   Correctly handle raising deferred errors in CLI lazy loading.
 :issue:`4096`
-   The CLI loader handles ``**kwargs`` in a ``create_app`` function.
 :issue:`4170`
-   Fix the order of ``before_request`` and other callbacks that trigger
 before the view returns. They are called from the app down to the
 closest nested blueprint. :issue:`4229`

2.0.1

-------------

Released 2021-05-21

-   Re-add the ``filename`` parameter in ``send_from_directory``. The
 ``filename`` parameter has been renamed to ``path``, the old name
 is deprecated. :pr:`4019`
-   Mark top-level names as exported so type checking understands
 imports in user projects. :issue:`4024`
-   Fix type annotation for ``g`` and inform mypy that it is a namespace
 object that has arbitrary attributes. :issue:`4020`
-   Fix some types that weren't available in Python 3.6.0. :issue:`4040`
-   Improve typing for ``send_file``, ``send_from_directory``, and
 ``get_send_file_max_age``. :issue:`4044`, :pr:`4026`
-   Show an error when a blueprint name contains a dot. The ``.`` has
 special meaning, it is used to separate (nested) blueprint names and
 the endpoint name. :issue:`4041`
-   Combine URL prefixes when nesting blueprints that were created with
 a ``url_prefix`` value. :issue:`4037`
-   Revert a change to the order that URL matching was done. The
 URL is again matched after the session is loaded, so the session is
 available in custom URL converters. :issue:`4053`
-   Re-add deprecated ``Config.from_json``, which was accidentally
 removed early. :issue:`4078`
-   Improve typing for some functions using ``Callable`` in their type
 signatures, focusing on decorator factories. :issue:`4060`
-   Nested blueprints are registered with their dotted name. This allows
 different blueprints with the same name to be nested at different
 locations. :issue:`4069`
-   ``register_blueprint`` takes a ``name`` option to change the
 (pre-dotted) name the blueprint is registered with. This allows the
 same blueprint to be registered multiple times with unique names for
 ``url_for``. Registering the same blueprint with the same name
 multiple times is deprecated. :issue:`1091`
-   Improve typing for ``stream_with_context``. :issue:`4052`

2.0.0

-------------

Released 2021-05-11

-   Drop support for Python 2 and 3.5.
-   Bump minimum versions of other Pallets projects: Werkzeug >= 2,
 Jinja2 >= 3, MarkupSafe >= 2, ItsDangerous >= 2, Click >= 8. Be sure
 to check the change logs for each project. For better compatibility
 with other applications (e.g. Celery) that still require Click 7,
 there is no hard dependency on Click 8 yet, but using Click 7 will
 trigger a DeprecationWarning and Flask 2.1 will depend on Click 8.
-   JSON support no longer uses simplejson. To use another JSON module,
 override ``app.json_encoder`` and ``json_decoder``. :issue:`3555`
-   The ``encoding`` option to JSON functions is deprecated. :pr:`3562`
-   Passing ``script_info`` to app factory functions is deprecated. This
 was not portable outside the ``flask`` command. Use
 ``click.get_current_context().obj`` if it's needed. :issue:`3552`
-   The CLI shows better error messages when the app failed to load
 when looking up commands. :issue:`2741`
-   Add ``SessionInterface.get_cookie_name`` to allow setting the
 session cookie name dynamically. :pr:`3369`
-   Add ``Config.from_file`` to load config using arbitrary file
 loaders, such as ``toml.load`` or ``json.load``.
 ``Config.from_json`` is deprecated in favor of this. :pr:`3398`
-   The ``flask run`` command will only defer errors on reload. Errors
 present during the initial call will cause the server to exit with
 the traceback immediately. :issue:`3431`
-   ``send_file`` raises a ``ValueError`` when passed an ``io`` object
 in text mode. Previously, it would respond with 200 OK and an empty
 file. :issue:`3358`
-   When using ad-hoc certificates, check for the cryptography library
 instead of PyOpenSSL. :pr:`3492`
-   When specifying a factory function with ``FLASK_APP``, keyword
 argument can be passed. :issue:`3553`
-   When loading a ``.env`` or ``.flaskenv`` file, the current working
 directory is no longer changed to the location of the file.
 :pr:`3560`
-   When returning a ``(response, headers)`` tuple from a view, the
 headers replace rather than extend existing headers on the response.
 For example, this allows setting the ``Content-Type`` for
 ``jsonify()``. Use ``response.headers.extend()`` if extending is
 desired. :issue:`3628`
-   The ``Scaffold`` class provides a common API for the ``Flask`` and
 ``Blueprint`` classes. ``Blueprint`` information is stored in
 attributes just like ``Flask``, rather than opaque lambda functions.
 This is intended to improve consistency and maintainability.
 :issue:`3215`
-   Include ``samesite`` and ``secure`` options when removing the
 session cookie. :pr:`3726`
-   Support passing a ``pathlib.Path`` to ``static_folder``. :pr:`3579`
-   ``send_file`` and ``send_from_directory`` are wrappers around the
 implementations in ``werkzeug.utils``. :pr:`3828`
-   Some ``send_file`` parameters have been renamed, the old names are
 deprecated. ``attachment_filename`` is renamed to ``download_name``.
 ``cache_timeout`` is renamed to ``max_age``. ``add_etags`` is
 renamed to ``etag``. :pr:`3828, 3883`
-   ``send_file`` passes ``download_name`` even if
 ``as_attachment=False`` by using ``Content-Disposition: inline``.
 :pr:`3828`
-   ``send_file`` sets ``conditional=True`` and ``max_age=None`` by
 default. ``Cache-Control`` is set to ``no-cache`` if ``max_age`` is
 not set, otherwise ``public``. This tells browsers to validate
 conditional requests instead of using a timed cache. :pr:`3828`
-   ``helpers.safe_join`` is deprecated. Use
 ``werkzeug.utils.safe_join`` instead. :pr:`3828`
-   The request context does route matching before opening the session.
 This could allow a session interface to change behavior based on
 ``request.endpoint``. :issue:`3776`
-   Use Jinja's implementation of the ``|tojson`` filter. :issue:`3881`
-   Add route decorators for common HTTP methods. For example,
 ``app.post("/login")`` is a shortcut for
 ``app.route("/login", methods=["POST"])``. :pr:`3907`
-   Support async views, error handlers, before and after request, and
 teardown functions. :pr:`3412`
-   Support nesting blueprints. :issue:`593, 1548`, :pr:`3923`
-   Set the default encoding to "UTF-8" when loading ``.env`` and
 ``.flaskenv`` files to allow to use non-ASCII characters. :issue:`3931`
-   ``flask shell`` sets up tab and history completion like the default
 ``python`` shell if ``readline`` is installed. :issue:`3941`
-   ``helpers.total_seconds()`` is deprecated. Use
 ``timedelta.total_seconds()`` instead. :pr:`3962`
-   Add type hinting. :pr:`3973`.

1.1.4

-------------

Released 2021-05-13

-   Update ``static_folder`` to use ``_compat.fspath`` instead of
 ``os.fspath`` to continue supporting Python < 3.6 :issue:`4050`

1.1.3

-------------

Released 2021-05-13

-   Set maximum versions of Werkzeug, Jinja, Click, and ItsDangerous.
 :issue:`4043`
-   Re-add support for passing a ``pathlib.Path`` for ``static_folder``.

-   Bump minimum version of SQLAlchemy to 2.0.16.
-   Remove previously deprecated code.
-   Pass extra keyword arguments from ``get_or_404`` to ``session.get``. :issue:`1149`
-   Fix bug with finding right bind key for clause statements. :issue:`1211`

3.0.5

-------------

Released 2023-06-21

-   ``Pagination.next()`` enforces ``max_per_page``. :issue:`1201`
-   Improve type hint for ``get_or_404`` return value to be non-optional. :pr:`1226`

3.0.4

-------------

Released 2023-06-19

-   Fix type hint for ``get_or_404`` return value. :pr:`1208`
-   Fix type hints for pyright (used by VS Code Pylance extension). :issue:`1205`

3.0.3

-------------

Released 2023-01-31

-   Show helpful errors when mistakenly using multiple ``SQLAlchemy`` instances for the
 same app, or without calling ``init_app``. :pr:`1151`
-   Fix issue with getting the engine associated with a model that uses polymorphic
 table inheritance. :issue:`1155`

3.0.2

-------------

Released 2022-10-14

-   Update compatibility with SQLAlchemy 2. :issue:`1122`

3.0.1

-------------

Released 2022-10-11

-   Export typing information instead of using external typeshed definitions.
 :issue:`1112`
-   If default engine options are set, but ``SQLALCHEMY_DATABASE_URI`` is not set, an
 invalid default bind will not be configured. :issue:`1117`

3.0.0

-------------

Released 2022-10-04

-   Drop support for Python 2, 3.4, 3.5, and 3.6.
-   Bump minimum version of Flask to 2.2.
-   Bump minimum version of SQLAlchemy to 1.4.18.
-   Remove previously deprecated code.
-   The session is scoped to the current app context instead of the thread. This
 requires that an app context is active. This ensures that the session is cleaned up
 after every request.
-   An active Flask application context is always required to access ``session`` and
 ``engine``, regardless of if an application was passed to the constructor.
 :issue:`508, 944`
-   Different bind keys use different SQLAlchemy ``MetaData`` registries, allowing
 tables in different databases to have the same name. Bind keys are stored and looked
 up on the resulting metadata rather than the model or table.
-   ``SQLALCHEMY_DATABASE_URI`` does not default to ``sqlite:///:memory:``. An error is
 raised if neither it nor ``SQLALCHEMY_BINDS`` define any engines. :pr:`731`
-   Configuring SQLite with a relative path is relative to ``app.instance_path`` instead
 of ``app.root_path``. The instance folder is created if necessary. :issue:`462`
-   Added ``get_or_404``, ``first_or_404``, ``one_or_404``, and ``paginate`` methods to
 the extension object. These use SQLAlchemy's preferred ``session.execute(select())``
 pattern instead of the legacy query interface. :issue:`1088`
-   Setup methods that create the engines and session are renamed with a leading
 underscore. They are considered internal interfaces which may change at any time.
-   All parameters to ``SQLAlchemy`` except ``app`` are keyword-only.
-   Renamed the ``bind`` parameter to ``bind_key`` and removed the ``app`` parameter
 from various ``SQLAlchemy`` methods.
-   The extension object uses ``__getattr__`` to alias names from the SQLAlchemy
 package, rather than copying them as attributes.
-   The extension object is stored directly as ``app.extensions["sqlalchemy"]``.
 :issue:`698`
-   The session class can be customized by passing the ``class_`` key in the
 ``session_options`` parameter. :issue:`327`
-   ``SignallingSession`` is renamed to ``Session``.
-   ``Session.get_bind`` more closely matches the base implementation.
-   Model classes and the ``db`` instance are available without imports in
 ``flask shell``. :issue:`1089`
-   The ``CamelCase`` to ``snake_case`` table name converter handles more patterns
 correctly. If model that was already created in the database changed, either use
 Alembic to rename the table, or set ``__tablename__`` to keep the old name.
 :issue:`406`
-   ``Model`` ``repr`` distinguishes between transient and pending instances.
 :issue:`967`
-   A custom model class can implement ``__init_subclass__`` with class parameters.
 :issue:`1002`
-   ``db.Table`` is a subclass instead of a function.
-   The ``engine_options`` parameter is applied as defaults before per-engine
 configuration.
-   ``SQLALCHEMY_BINDS`` values can either be an engine URL, or a dict of engine options
 including URL, for each bind. ``SQLALCHEMY_DATABASE_URI`` and
 ``SQLALCHEMY_ENGINE_OPTIONS`` correspond to the ``None`` key and take precedence.
 :issue:`783`
-   Engines are created when calling ``init_app`` rather than the first time they are
 accessed. :issue:`698`
-   ``db.engines`` exposes the map of bind keys to engines for the current app.
-   ``get_engine``, ``get_tables_for_bind``, and ``get_binds`` are deprecated.
-   SQLite driver-level URIs that look like ``sqlite:///file:name.db?uri=true`` are
 supported. :issue:`998, 1045`
-   SQLite engines do not use ``NullPool`` if ``pool_size`` is 0.
-   MySQL engines use the "utf8mb4" charset by default. :issue:`875`
-   MySQL engines do not set ``pool_size`` to 10.
-   MySQL engines don't set a default for ``pool_recycle`` if not using a queue pool.
 :issue:`803`
-   ``Query`` is renamed from ``BaseQuery``.
-   Added ``Query.one_or_404``.
-   The query class is applied to ``backref`` in ``relationship``. :issue:`417`
-   Creating ``Pagination`` objects manually is no longer a public API. They should be
 created with ``db.paginate`` or ``query.paginate``. :issue:`1088`
-   ``Pagination.iter_pages`` and ``Query.paginate`` parameters are keyword-only.
-   ``Pagination`` is iterable, iterating over its items. :issue:`70`
-   Pagination count query is more efficient.
-   ``Pagination.iter_pages`` is more efficient. :issue:`622`
-   ``Pagination.iter_pages`` ``right_current`` parameter is inclusive.
-   Pagination ``per_page`` cannot be 0. :issue:`1091`
-   Pagination ``max_per_page`` defaults to 100. :issue:`1091`
-   Added ``Pagination.first`` and ``last`` properties, which give the number of the
 first and last item on the page. :issue:`567`
-   ``SQLALCHEMY_RECORD_QUERIES`` is disabled by default, and is not enabled
 automatically with ``app.debug`` or ``app.testing``. :issue:`1092`
-   ``get_debug_queries`` is renamed to ``get_recorded_queries`` to better match the
 config and functionality.
-   Recorded query info is a dataclass instead of a tuple. The ``context`` attribute is
 renamed to ``location``. Finding the location uses a more inclusive check.
-   ``SQLALCHEMY_TRACK_MODIFICATIONS`` is disabled by default. :pr:`727`
-   ``SQLALCHEMY_COMMIT_ON_TEARDOWN`` is deprecated. It can cause various design issues
 that are difficult to debug. Call ``db.session.commit()`` directly instead.
 :issue:`216`

2.5.1

-------------

Released 2021-03-18

-   Fix compatibility with Python 2.7.

2.5.0

-------------

Released 2021-03-18

-   Update to support SQLAlchemy 1.4.
-   SQLAlchemy ``URL`` objects are immutable. Some internal methods have changed to
 return a new URL instead of ``None``. :issue:`885`

Changelog

2.0.36

:released: October 15, 2024

 .. change::
     :tags: bug, schema
     :tickets: 11317

     Fixed bug where SQL functions passed to
     :paramref:`_schema.Column.server_default` would not be rendered with the
     particular form of parenthesization now required by newer versions of MySQL
     and MariaDB. Pull request courtesy of huuya.

 .. change::
     :tags: bug, orm
     :tickets: 11912

     Fixed bug in ORM bulk update/delete where using RETURNING with bulk
     update/delete in combination with ``populate_existing`` would fail to
     accommodate the ``populate_existing`` option.

 .. change::
     :tags: bug, orm
     :tickets: 11917

     Continuing from :ticket:`11912`, columns marked with
     :paramref:`.mapped_column.onupdate`,
     :paramref:`.mapped_column.server_onupdate`, or :class:`.Computed` are now
     refreshed in ORM instances when running an ORM enabled UPDATE with WHERE
     criteria, even if the statement does not use RETURNING or
     ``populate_existing``.

 .. change::
     :tags: usecase, orm
     :tickets: 11923

     Added new parameter :paramref:`_orm.mapped_column.hash` to ORM constructs
     such as :meth:`_orm.mapped_column`, :meth:`_orm.relationship`, etc.,
     which is interpreted for ORM Native Dataclasses in the same way as other
     dataclass-specific field parameters.

 .. change::
     :tags: bug, postgresql, reflection
     :tickets: 11961

     Fixed bug in reflection of table comments where unrelated text would be
     returned if an entry in the ``pg_description`` table happened to share the
     same oid (objoid) as the table being reflected.

 .. change::
     :tags: bug, orm
     :tickets: 11965

     Fixed regression caused by fixes to joined eager loading in :ticket:`11449`
     released in 2.0.31, where a particular joinedload case could not be
     asserted correctly.   We now have an example of that case so the assertion
     has been repaired to allow for it.


 .. change::
     :tags: orm, bug
     :tickets: 11973

     Improved the error message emitted when trying to map as dataclass a class
     while also manually providing the ``__table__`` attribute.
     This usage is currently not supported.

 .. change::
     :tags: mysql, performance
     :tickets: 11975

     Improved a query used for the MySQL 8 backend when reflecting foreign keys
     to be better optimized.   Previously, for a database that had millions of
     columns across all tables, the query could be prohibitively slow; the query
     has been reworked to take better advantage of existing indexes.

 .. change::
     :tags: usecase, sql
     :tickets: 11978

     Datatypes that are binary based such as :class:`.VARBINARY` will resolve to
     :class:`.LargeBinary` when the :meth:`.TypeEngine.as_generic()` method is
     called.

 .. change::
     :tags: postgresql, bug
     :tickets: 11994

     The :class:`.postgresql.JSON` and :class:`.postgresql.JSONB` datatypes will
     now render a "bind cast" in all cases for all PostgreSQL backends,
     including psycopg2, whereas previously it was only enabled for some
     backends.   This allows greater accuracy in allowing the database server to
     recognize when a string value is to be interpreted as JSON.

 .. change::
     :tags: bug, orm
     :tickets: 11995

     Refined the check which the ORM lazy loader uses to detect "this would be
     loading by primary key and the primary key is NULL, skip loading" to take
     into account the current setting for the
     :paramref:`.orm.Mapper.allow_partial_pks` parameter. If this parameter is
     ``False``, then a composite PK value that has partial NULL elements should
     also be skipped.   This can apply to some composite overlapping foreign key
     configurations.


 .. change::
     :tags: bug, orm
     :tickets: 11997

     Fixed bug in ORM "update with WHERE clause" feature where an explicit
     ``.returning()`` would interfere with the "fetch" synchronize strategy due
     to an assumption that the ORM mapped class featured the primary key columns
     in a specific position within the RETURNING.  This has been fixed to use
     appropriate ORM column targeting.

 .. change::
     :tags: bug, sql, regression
     :tickets: 12002

     Fixed regression from 1.4 where some datatypes such as those derived from
     :class:`.TypeDecorator` could not be pickled when they were part of a
     larger SQL expression composition due to internal supporting structures
     themselves not being pickleable.

.. changelog::

2.0.35

:released: September 16, 2024

 .. change::
     :tags: bug, orm, typing
     :tickets: 11820

     Fixed issue where it was not possible to use ``typing.Literal`` with
     ``Mapped[]`` on Python 3.8 and 3.9.  Pull request courtesy Frazer McLean.

 .. change::
     :tags: bug, sqlite, regression
     :tickets: 11840

     The changes made for SQLite CHECK constraint reflection in versions 2.0.33
     and 2.0.34 , :ticket:`11832` and :ticket:`11677`, have now been fully
     reverted, as users continued to identify existing use cases that stopped
     working after this change.   For the moment, because SQLite does not
     provide any consistent way of delivering information about CHECK
     constraints, SQLAlchemy is limited in what CHECK constraint syntaxes can be
     reflected, including that a CHECK constraint must be stated all on a
     single, independent line (or inline on a column definition)  without
     newlines, tabs in the constraint definition or unusual characters in the
     constraint name.  Overall, reflection for SQLite is tailored towards being
     able to reflect CREATE TABLE statements that were originally created by
     SQLAlchemy DDL constructs.  Long term work on a DDL parser that does not
     rely upon regular expressions may eventually improve upon this situation.
     A wide range of additional cross-dialect CHECK constraint reflection tests
     have been added as it was also a bug that these changes did not trip any
     existing tests.

 .. change::
     :tags: orm, bug
     :tickets: 11849

     Fixed issue in ORM evaluator where two datatypes being evaluated with the
     SQL concatenator operator would not be checked for
     :class:`.UnevaluatableError` based on their datatype; this missed the case
     of :class:`_postgresql.JSONB` values being used in a concatenate operation
     which is supported by PostgreSQL as well as how SQLAlchemy renders the SQL
     for this operation, but does not work at the Python level. By implementing
     :class:`.UnevaluatableError` for this combination, ORM update statements
     will now fall back to "expire" when a concatenated JSON value used in a SET
     clause is to be synchronized to a Python object.

 .. change::
     :tags: bug, orm
     :tickets: 11853

     An warning is emitted if :func:`_orm.joinedload` or
     :func:`_orm.subqueryload` are used as a top level option against a
     statement that is not a SELECT statement, such as with an
     ``insert().returning()``.   There are no JOINs in INSERT statements nor is
     there a "subquery" that can be repurposed for subquery eager loading, and
     for UPDATE/DELETE joinedload does not support these either, so it is never
     appropriate for this use to pass silently.

 .. change::
     :tags: bug, orm
     :tickets: 11855

     Fixed issue where using loader options such as :func:`_orm.selectinload`
     with additional criteria in combination with ORM DML such as
     :func:`_sql.insert` with RETURNING would not correctly set up internal
     contexts required for caching to work correctly, leading to incorrect
     results.

 .. change::
     :tags: bug, mysql
     :tickets: 11870

     Fixed issue in mariadbconnector dialect where query string arguments that
     weren't checked integer or boolean arguments would be ignored, such as
     string arguments like ``unix_socket``, etc.  As part of this change, the
     argument parsing for particular elements such as ``client_flags``,
     ``compress``, ``local_infile`` has been made more consistent across all
     MySQL / MariaDB dialect which accept each argument. Pull request courtesy
     Tobias Alex-Petersen.


.. changelog::

2.0.34

:released: September 4, 2024

 .. change::
     :tags: bug, orm
     :tickets: 11831

     Fixed regression caused by issue :ticket:`11814` which broke support for
     certain flavors of :pep:`593` ``Annotated`` in the type_annotation_map when
     builtin types such as ``list``, ``dict`` were used without an element type.
     While this is an incomplete style of typing, these types nonetheless
     previously would be located in the type_annotation_map correctly.

 .. change::
     :tags: bug, sqlite
     :tickets: 11832

     Fixed regression in SQLite reflection caused by :ticket:`11677` which
     interfered with reflection for CHECK constraints that were followed
     by other kinds of constraints within the same table definition.   Pull
     request courtesy Harutaka Kawamura.


.. changelog::

2.0.33

:released: September 3, 2024

 .. change::
     :tags: bug, sqlite
     :tickets: 11677

     Improvements to the regex used by the SQLite dialect to reflect the name
     and contents of a CHECK constraint.  Constraints with newline, tab, or
     space characters in either or both the constraint text and constraint name
     are now properly reflected.   Pull request courtesy Jeff Horemans.



 .. change::
     :tags: bug, engine
     :tickets: 11687

     Fixed issue in internal reflection cache where particular reflection
     scenarios regarding same-named quoted_name() constructs would not be
     correctly cached.  Pull request courtesy Felix Lüdin.

 .. change::
     :tags: bug, sql, regression
     :tickets: 11703

     Fixed regression in :meth:`_sql.Select.with_statement_hint` and others
     where the generative behavior of the method stopped producing a copy of the
     object.

 .. change::
     :tags: bug, mysql
     :tickets: 11731

     Fixed issue in MySQL dialect where using INSERT..FROM SELECT in combination
     with ON DUPLICATE KEY UPDATE would erroneously render on MySQL 8 and above
     the "AS new" clause, leading to syntax failures.  This clause is required
     on MySQL 8 to follow the VALUES clause if use of the "new" alias is
     present, however is not permitted to follow a FROM SELECT clause.


 .. change::
     :tags: bug, sqlite
     :tickets: 11746

     Improvements to the regex used by the SQLite dialect to reflect the name
     and contents of a UNIQUE constraint that is defined inline within a column
     definition inside of a SQLite CREATE TABLE statement, accommodating for tab
     characters present within the column / constraint line. Pull request
     courtesy John A Stevenson.




 .. change::
     :tags: bug, typing
     :tickets: 11782

     Fixed typing issue with :meth:`_sql.Select.with_only_columns`.

 .. change::
     :tags: bug, orm
     :tickets: 11788

     Correctly cleanup the internal top-level module registry when no
     inner modules or classes are registered into it.

 .. change::
     :tags: bug, schema
     :tickets: 11802

     Fixed bug where the ``metadata`` element of an ``Enum`` datatype would not
     be transferred to the new :class:`.MetaData` object when the type had been
     copied via a :meth:`.Table.to_metadata` operation, leading to inconsistent
     behaviors within create/drop sequences.

 .. change::
     :tags: bug, orm
     :tickets: 11814

     Improvements to the ORM annotated declarative type map lookup dealing with
     composed types such as ``dict[str, Any]`` linking to JSON (or others) with
     or without "future annotations" mode.



 .. change::
     :tags: change, general
     :tickets: 11818

     The pin for ``setuptools<69.3`` in ``pyproject.toml`` has been removed.
     This pin was to prevent a sudden change in setuptools to use :pep:`625`
     from taking place, which would change the file name of SQLAlchemy's source
     distribution on pypi to be an all lower case name, which is likely to cause
     problems with various build environments that expected the previous naming
     style.  However, the presence of this pin is holding back environments that
     otherwise want to use a newer setuptools, so we've decided to move forward
     with this change, with the assumption that build environments will have
     largely accommodated the setuptools change by now.



 .. change::
     :tags: bug, postgresql
     :tickets: 11821

     Revising the asyncpg ``terminate()`` fix first made in :ticket:`10717`
     which improved the resiliency of this call under all circumstances, adding
     ``asyncio.CancelledError`` to the list of exceptions that are intercepted
     as failing for a graceful ``.close()`` which will then proceed to call
     ``.terminate()``.

 .. change::
     :tags: bug, mssql
     :tickets: 11822

     Added error "The server failed to resume the transaction" to the list of
     error strings for the pymssql driver in determining a disconnect scenario,
     as observed by one user using pymssql under otherwise unknown conditions as
     leaving an unusable connection in the connection pool which fails to ping
     cleanly.

 .. change::
     :tags: bug, tests

     Added missing ``array_type`` property to the testing suite
     ``SuiteRequirements`` class.

.. changelog::

2.0.32

:released: August 5, 2024

 .. change::
     :tags: bug, examples
     :tickets: 10267

     Fixed issue in history_meta example where the "version" column in the
     versioned table needs to default to the most recent version number in the
     history table on INSERT, to suit the use case of a table where rows are
     deleted, and can then be replaced by new rows that re-use the same primary
     key identity.  This fix adds an additonal SELECT query per INSERT in the
     main table, which may be inefficient; for cases where primary keys are not
     re-used, the default function may be omitted.  Patch courtesy  Philipp H.
     v. Loewenfeld.

 .. change::
     :tags: bug, oracle
     :tickets: 11557

     Fixed table reflection on Oracle 10.2 and older where compression options
     are not supported.

 .. change::
     :tags: oracle, usecase
     :tickets: 10820

     Added API support for server-side cursors for the oracledb async dialect,
     allowing use of the :meth:`_asyncio.AsyncConnection.stream` and similar
     stream methods.

 .. change::
     :tags: bug, orm
     :tickets: 10834

     Fixed issue where using the :meth:`_orm.Query.enable_eagerloads` and
     :meth:`_orm.Query.yield_per` methods at the same time, in order to disable
     eager loading that's configured on the mapper directly, would be silently
     ignored, leading to errors or unexpected eager population of attributes.

 .. change::
     :tags: orm
     :tickets: 11163

     Added a warning noting when an
     :meth:`_engine.ConnectionEvents.engine_connect` event may be leaving
     a transaction open, which can alter the behavior of a
     :class:`_orm.Session` using such an engine as bind.
     On SQLAlchemy 2.1 :paramref:`_orm.Session.join_transaction_mode` will
     instead be ignored in all cases when the session bind is
     an :class:`_engine.Engine`.

 .. change::
     :tags: bug, general, regression
     :tickets: 11435

     Restored legacy class names removed from
     ``sqlalalchemy.orm.collections.*``, including
     :class:`_orm.MappedCollection`, :func:`_orm.mapped_collection`,
     :func:`_orm.column_mapped_collection`,
     :func:`_orm.attribute_mapped_collection`. Pull request courtesy Takashi
     Kajinami.

 .. change::
     :tags: bug, sql
     :tickets: 11471

     Follow up of :ticket:`11471` to fix caching issue where using the
     :meth:`.CompoundSelectState.add_cte` method of the
     :class:`.CompoundSelectState` construct would not set a correct cache key
     which distinguished between different CTE expressions. Also added tests
     that would detect issues similar to the one fixed in :ticket:`11544`.

 .. change::
     :tags: bug, mysql
     :tickets: 11479

     Fixed issue in MySQL dialect where ENUM values that contained percent signs
     were not properly escaped for the driver.


 .. change::
     :tags: usecase, oracle
     :tickets: 11480

     Implemented two-phase transactions for the oracledb dialect. Historically,
     this feature never worked with the cx_Oracle dialect, however recent
     improvements to the oracledb successor now allow this to be possible.  The
     two phase transaction API is available at the Core level via the
     :meth:`_engine.Connection.begin_twophase` method.

 .. change::
     :tags: bug, postgresql
     :tickets: 11522

     It is now considered a pool-invalidating disconnect event when psycopg2
     throws an "SSL SYSCALL error: Success" error message, which can occur when
     the SSL connection to Postgres is terminated abnormally.

 .. change::
     :tags: bug, schema
     :tickets: 11530

     Fixed additional issues in the event system triggered by unpickling of a
     :class:`.Enum` datatype, continuing from :ticket:`11365` and
     :ticket:`11360`,  where dynamically generated elements of the event
     structure would not be present when unpickling in a new process.

 .. change::
     :tags: bug, engine
     :tickets: 11532

     Fixed issue in "insertmanyvalues" feature where a particular call to
     ``cursor.fetchall()`` were not wrapped in SQLAlchemy's exception wrapper,
     which apparently can raise a database exception during fetch when using
     pyodbc.

     :tickets: 11575

     The :paramref:`_orm.aliased.name` parameter to :func:`_orm.aliased` may now
     be combined with the :paramref:`_orm.aliased.flat` parameter, producing
     per-table names based on a name-prefixed naming convention.  Pull request
     courtesy Eric Atkin.

 .. change::
     :tags: bug, postgresql
     :tickets: 11576

     Fixed issue where the :func:`_sql.collate` construct, which explicitly sets
     a collation for a given expression, would maintain collation settings for
     the underlying type object from the expression, causing SQL expressions to
     have both collations stated at once when used in further expressions for
     specific dialects that render explicit type casts, such as that of asyncpg.
     The :func:`_sql.collate` construct now assigns its own type to explicitly
     include the new collation, assuming it's a string type.

 .. change::
     :tags: bug, sql
     :tickets: 11592

     Fixed bug where the :meth:`.Operators.nulls_first()` and
     :meth:`.Operators.nulls_last()` modifiers would not be treated the same way
     as :meth:`.Operators.desc()` and :meth:`.Operators.asc()` when determining
     if an ORDER BY should be against a label name already in the statement. All
     four modifiers are now treated the same within ORDER BY.

 .. change::
     :tags: bug, orm, regression
     :tickets: 11625

     Fixed regression appearing in 2.0.21 caused by :ticket:`10279` where using
     a :func:`_sql.delete` or :func:`_sql.update` against an ORM class that is
     the base of an inheritance hierarchy, while also specifying that subclasses
     should be loaded polymorphically, would leak the polymorphic joins into the
     UPDATE or DELETE statement as well creating incorrect SQL.

 .. change::
     :tags: bug, orm, regression
     :tickets: 11661

     Fixed regression from version 1.4 in
     :meth:`_orm.Session.bulk_insert_mappings` where using the
     :paramref:`_orm.Session.bulk_insert_mappings.return_defaults` parameter
     would not populate the passed in dictionaries with newly generated primary
     key values.


 .. change::
     :tags: bug, oracle, sqlite
     :tickets: 11663

     Implemented bitwise operators for Oracle which was previously
     non-functional due to a non-standard syntax used by this database.
     Oracle's support for bitwise "or" and "xor" starts with server version 21.
     Additionally repaired the implementation of "xor" for SQLite.

     As part of this change, the dialect compliance test suite has been enhanced
     to include support for server-side bitwise tests; third party dialect
     authors should refer to new "supports_bitwise" methods in the
     requirements.py file to enable these tests.




 .. change::
     :tags: bug, typing

     Fixed internal typing issues to establish compatibility with mypy 1.11.0.
     Note that this does not include issues which have arisen with the
     deprecated mypy plugin used by SQLAlchemy 1.4-style code; see the addiional
     change note for this plugin indicating revised compatibility.

2.0.31

:released: June 18, 2024

 .. change::
     :tags: usecase, reflection, mysql
     :tickets: 11285

     Added missing foreign key reflection option ``SET DEFAULT``
     in the MySQL and MariaDB dialects.
     Pull request courtesy of Quentin Roche.

 .. change::
     :tags: usecase, orm
     :tickets: 11361

     Added missing parameter :paramref:`_orm.with_polymorphic.name` that
     allows specifying the name of returned :class:`_orm.AliasedClass`.

 .. change::
     :tags: bug, orm
     :tickets: 11365

     Fixed issue where a :class:`.MetaData` collection would not be
     serializable, if an :class:`.Enum` or :class:`.Boolean` datatype were
     present which had been adapted. This specific scenario in turn could occur
     when using the :class:`.Enum` or :class:`.Boolean` within ORM Annotated
     Declarative form where type objects frequently get copied.

 .. change::
     :tags: schema, usecase
     :tickets: 11374

     Added :paramref:`_schema.Column.insert_default` as an alias of
     :paramref:`_schema.Column.default` for compatibility with
     :func:`_orm.mapped_column`.

 .. change::
     :tags: bug, general
     :tickets: 11417

     Set up full Python 3.13 support to the extent currently possible, repairing
     issues within internal language helpers as well as the serializer extension
     module.

 .. change::
     :tags: bug, sql
     :tickets: 11422

     Fixed issue when serializing an :func:`_sql.over` clause with
     unbounded range or rows.

 .. change::
     :tags: bug, sql
     :tickets: 11423

     Added missing methods :meth:`_sql.FunctionFilter.within_group`
     and :meth:`_sql.WithinGroup.filter`

 .. change::
     :tags: bug, sql
     :tickets: 11426

     Fixed bug in :meth:`_sql.FunctionFilter.filter` that would mutate
     the existing function in-place. It now behaves like the rest of the
     SQLAlchemy API, returning a new instance instead of mutating the
     original one.

 .. change::
     :tags: bug, orm
     :tickets: 11446

     Fixed issue where the :func:`_orm.selectinload` and
     :func:`_orm.subqueryload` loader options would fail to take effect when
     made against an inherited subclass that itself included a subclass-specific
     :paramref:`_orm.Mapper.with_polymorphic` setting.

 .. change::
     :tags: bug, orm
     :tickets: 11449

     Fixed very old issue involving the :paramref:`_orm.joinedload.innerjoin`
     parameter where making use of this parameter mixed into a query that also
     included joined eager loads along a self-referential or other cyclical
     relationship, along with complicating factors like inner joins added for
     secondary tables and such, would have the chance of splicing a particular
     inner join to the wrong part of the query.  Additional state has been added
     to the internal method that does this splice to make a better decision as
     to where splicing should proceed.

 .. change::
     :tags: bug, orm, regression
     :tickets: 11509

     Fixed bug in ORM Declarative where the ``__table__`` directive could not be
     declared as a class function with :func:`_orm.declared_attr` on a
     superclass, including an ``__abstract__`` class as well as coming from the
     declarative base itself.  This was a regression since 1.4 where this was
     working, and there were apparently no tests for this particular use case.

.. changelog::

2.0.30

:released: May 5, 2024

 .. change::
     :tags: bug, typing, regression
     :tickets: 11200

     Fixed typing regression caused by :ticket:`11055` in version 2.0.29 that
     added ``ParamSpec`` to the asyncio ``run_sync()`` methods, where using
     :meth:`_asyncio.AsyncConnection.run_sync` with
     :meth:`_schema.MetaData.reflect` would fail on mypy due to a mypy issue.
     Pull request courtesy of Francisco R. Del Roio.

 .. change::
     :tags: bug, engine
     :tickets: 11210

     Fixed issue in the
     :paramref:`_engine.Connection.execution_options.logging_token` option,
     where changing the value of ``logging_token`` on a connection that has
     already logged messages would not be updated to reflect the new logging
     token.  This in particular prevented the use of
     :meth:`_orm.Session.connection` to change the option on the connection,
     since the BEGIN logging message would already have been emitted.

 .. change::
     :tags: bug, orm
     :tickets: 11220

     Added new attribute :attr:`_orm.ORMExecuteState.is_from_statement` to
     detect statements created using :meth:`_sql.Select.from_statement`, and
     enhanced ``FromStatement`` to set :attr:`_orm.ORMExecuteState.is_select`,
     :attr:`_orm.ORMExecuteState.is_insert`,
     :attr:`_orm.ORMExecuteState.is_update`, and
     :attr:`_orm.ORMExecuteState.is_delete` according to the element that is
     sent to the :meth:`_sql.Select.from_statement` method itself.

 .. change::
     :tags: bug, test
     :tickets: 11268

     Ensure the ``PYTHONPATH`` variable is properly initialized when
     using ``subprocess.run`` in the tests.

 .. change::
     :tags: bug, orm
     :tickets: 11291

     Fixed issue in  :func:`_orm.selectin_polymorphic` loader option where
     attributes defined with :func:`_orm.composite` on a superclass would cause
     an internal exception on load.


 .. change::
     :tags: bug, orm, regression
     :tickets: 11292

     Fixed regression from 1.4 where using :func:`_orm.defaultload` in
     conjunction with a non-propagating loader like :func:`_orm.contains_eager`
     would nonetheless propagate the :func:`_orm.contains_eager` to a lazy load
     operation, causing incorrect queries as this option is only intended to
     come from an original load.



 .. change::
     :tags: bug, orm
     :tickets: 11305

     Fixed issue in ORM Annotated Declarative where typing issue where literals
     defined using :pep:`695` type aliases would not work with inference of
     :class:`.Enum` datatypes. Pull request courtesy of Alc-Alc.

 .. change::
     :tags: bug, engine
     :tickets: 11306

     Fixed issue in cursor handling which affected handling of duplicate
     :class:`_sql.Column` or similar objcts in the columns clause of
     :func:`_sql.select`, both in combination with arbitary :func:`_sql.text()`
     clauses in the SELECT list, as well as when attempting to retrieve
     :meth:`_engine.Result.mappings` for the object, which would lead to an
     internal error.



 .. change::
     :tags: bug, orm
     :tickets: 11327

     Fixed issue in :func:`_orm.selectin_polymorphic` loader option where the
     SELECT emitted would only accommodate for the child-most class among the
     result rows that were returned, leading intermediary-class attributes to be
     unloaded if there were no concrete instances of that intermediary-class
     present in the result.   This issue only presented itself for multi-level
     inheritance hierarchies.

 .. change::
     :tags: bug, orm
     :tickets: 11332

     Fixed issue in :meth:`_orm.Session.bulk_save_objects` where the form of the
     identity key produced when using ``return_defaults=True`` would be
     incorrect. This could lead to an errors during pickling as well as identity
     map mismatches.

 .. change::
     :tags: bug, installation
     :tickets: 11334

     Fixed an internal class that was testing for unexpected attributes to work
     correctly under upcoming Python 3.13.   Pull request courtesy Edgar
     Ramírez-Mondragón.

 .. change::
     :tags: bug, orm
     :tickets: 11347

     Fixed issue where attribute key names in :class:`_orm.Bundle` would not be
     correct when using ORM enabled :class:`_sql.select` vs.
     :class:`_orm.Query`, when the statement contained duplicate column names.

 .. change::
     :tags: bug, typing

     Fixed issue in typing for :class:`_orm.Bundle` where creating a nested
     :class:`_orm.Bundle` structure were not allowed.
