v2.0.0a0

Changes from v1.x

Breaking changes:

• Added support for Python 3.12
• Dropped support for Python 3.7
• Flask-BabelEx is no longer supported; the package is no longer maintained and Flask-Babel is recommended/active instead.
• Flask-Mongoengine is no longer supported due to that package being unmaintained.
• Bootstrap2 and Bootstrap3 themes are no longer available.
• Admin() now takes a theme parameter that encapsulates all of the configuration options for theming the admin instance. This replaces the template_mode parameter.
• All remaining Flask-Admin config has been namespaced under FLASK_ADMIN_.

Title

New features:

• Flask-Admin now supports the host_matching mode of Flask apps. See documentation for how to configure this where needed.
• Flask-Admin is now compatible with SQLAlchemy v2+, Flask v3+, WTForms v3+, and Pillow v10+.
• Flask-Admin now declares its dependencies and supported dependency versions more cleanly, including using pip extras. If you use Flask-Admin with SQLAlchemy, for example, you should use pip install flask-admin[sqlalchemy] or list flask-admin[sqlalchemy] in your requirements.txt or pyproject.toml files.
• Apps using content security policies to restrict the assets that can be loaded can now whitelist Flask-Admin’s assets by passing a csp_nonce_generator function to the Admin instance. See examples or documentation for how to configure this where needed.
• page_size_options can now be configured on Admin models, to restrict the page sizes that users can select. These are now enforced properly and cannot be bypassed by URL hacking.
