Version 2.4.3
-------------

Released 2020-05-26

Released 2020-05-25

Log message:
py-flaks-sqlalchemy: updated to 2.3.2

Version 2.3.2
- Don't mask the parent table for single-table inheritance models.

Version 2.3.1
- If a model has a table name that matches an existing table in the metadata,
  use that table. Fixes a regression where reflected tables were not picked up
  by models.
- Raise the correct error when a model has a table name but no primary key.
- Fix repr on models that don't have an identity because they have not been
  flushed yet.
- Allow specifying a max_per_page limit for pagination, to avoid users
  specifying high values in the request args.
- For paginate with error_out=False, the minimum value for page is
  1 and per_page is 0.

Version 2.3.0
- Multiple bugs with __tablename__ generation are fixed. Names will be
  generated for models that define a primary key, but not for single-table
  inheritance subclasses. Names will not override a declared_attr.
  PrimaryKeyConstraint is detected.
- Passing an existing declarative_base() as model_class to
  SQLAlchemy.__init__ will use this as the base class instead of creating
  one. This allows customizing the metaclass used to construct the base.
- The undocumented DeclarativeMeta internals that the extension uses for
  binds and table name generation have been refactored to work as mixins.
  Documentation is added about how to create a custom metaclass that does not
  do table name generation.
- Model and metaclass code has been moved to a new models module.
  _BoundDeclarativeMeta is renamed to DefaultMeta; the old name will be
  removed in 3.0.
- Models have a default repr that shows the model name and primary key.
- Fixed a bug where using init_app would cause connectors to always use the
  current_app rather than the app they were created for. This caused issues
  when multiple apps were registered with the extension.

Log message:
Update py-flask-sqlalchemy to 2.2.

Version 2.2
-----------

Released on February 27, 2017, codename Dubnium

- Minimum SQLAlchemy version is 0.8 due to use of ``sqlalchemy.inspect``.
- Added support for custom ``query_class`` and ``model_class`` as args
  to the ``SQLAlchemy`` constructor. (`#328`_)
- Allow listening to SQLAlchemy events on ``db.session``. (`#364`_)
- Allow ``__bind_key__`` on abstract models. (`#373`_)
- Allow ``SQLALCHEMY_ECHO`` to be a string. (`#409`_)
- Warn when ``SQLALCHEMY_DATABASE_URI`` is not set. (`#443`_)
- Don't let pagination generate invalid page numbers. (`#460`_)
- Drop support of Flask < 0.10. This means the db session is always tied to
  the app context and its teardown event. (`#461`_)
- Tablename generation logic no longer accesses class properties unless they
  are ``declared_attr``. (`#467`_)
