3.0.0

This is a feature release, which includes new features and removes previously deprecated code. The 3.0.x branch is now the supported bug fix branch, the 2.x branch will become a tag marking the end of support for that branch. We encourage everyone to upgrade, and to use a tool such as pip-tools to pin all dependencies and control upgrades.

3.0.0a2

This is a prerelease to preview the changes in 3.0, the next feature release. Prereleases are an opportunity to test and update your projects early before the final release.

pip install -U --pre Flask-SQLAlchemy

There were significant changes in pallets-eco/flask-sqlalchemy#1087, see the changelog for a full list. Many of those changes will raise deprecation warnings, but it was not feasible to implement warnings for some things.

Changelog

Sourced from flask-sqlalchemy's changelog.

Version 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

Version 3.0.2

Released 2022-10-14

• Update compatibility with SQLAlchemy 2. :issue:1122

Version 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

Version 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
