3.1.1

This is the Flask-Alembic 3.1.1 fix release. It fixes bugs but does not otherwise change behavior and should not result in breaking changes.

PyPI: https://pypi.org/project/Flask-Alembic/3.1.1/
Changes: https://flask-alembic.readthedocs.io/page/changes/#version-3-1-1

• flask db merge merges all heads by default and does not require an argument.

3.1.0

This is the Flask-Alembic 3.1.0 feature release, which may include new features, remove previously deprecated code, or add new deprecations.

PyPI: https://pypi.org/project/Flask-Alembic/3.1.0/
Changes: https://flask-alembic.readthedocs.io/page/changes/

• Drop support for Python 3.8.
• Support Flask-SQLAlchemy-Lite and plain SQLAlchemy, in addition to Flask-SQLAlchemy.
• Support multiple databases, and multiple metadata per database.
• The constructor args run_mkdir and command_name are keyword only.
• Deprecate the init_app args run_mkdir and command_name. They can be passed to the constructor instead.
• Dict values in the ALEMBIC config are treated as Alembic config sections, allowing use of Alembic features like post_write_hooks.

3.0.1

This is a fix release for the 3.0.x feature release branch. It fixes bugs but does not otherwise change behavior and should not result in breaking changes.

Changes: https://flask-alembic.readthedocs.io/en/latest/changes/#version-3-0-1
PyPI: https://pypi.org/project/Flask-Alembic/3.0.1/

• Fix handling of relative ids (-1, +1) passed to downgrade and upgrade.

3.0.0

This updates compatibility with Flask-SQLAlchemy 3.1, and generally modernizes the project layout, tooling, code, and minimum versions. I've made this a milestone release (3.0) rather than a feature release (2.1) given that the library has gone so long without needing an update.
