Breaking changes from v1.6.1: * Removed support for Python <3.10 * Use of the `boto` library has been replaced by `boto3`. S3FileAdmin and S3Storage now accept an `s3_client` parameter taking a `boto3.client('s3')` instance rather than `aws_access_key_id`, `aws_secret_access_key`, and `region` parameters. * Azure Blob Storage SDK has been upgraded from the legacy version (v2) to the latest version (v12). AzureFileAdmin now accept `blob_service_client` rather than `connection_string` to give more flexibility with connection types. * Flask-BabelEx is no longer supported; the package is no longer maintained and Flask-Babel is recommended/active instead. * Mongoengine support in Flask-Admin no longer uses Flask-Mongoengine, as that library is no longer actively maintained. * 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_`. | Config variable name | What's changed | |------------------------------------|------------------------------------| | FLASK_ADMIN_SWATCH | Removed; use <span class="title-ref">Theme(swatch=...)</span> instead | | FLASK_ADMIN_FLUID_LAYOUT | Removed; use <span class="title-ref">Theme(fluid=...)</span> instead | | MAPBOX_MAP_ID | Renamed to FLASK_ADMIN_MAPBOX_MAP_ID | | MAPBOX_SEARCH | Renamed to FLASK_ADMIN_MAPBOX_SEARCH | | MAPBOX_ACCESS_TOKEN | Renamed to FLASK_ADMIN_MAPBOX_ACCESS_TOKEN | | GOOGLE_MAPS_API_KEY | Renamed to FLASK_ADMIN_GOOGLE_MAPS_API_KEY | | DEFAULT_CENTER_LAT | Renamed to FLASK_ADMIN_DEFAULT_CENTER_LAT | | DEFAULT_CENTER_LONG | Renamed to FLASK_ADMIN_DEFAULT_CENTER_LONG | | ADMIN_RAISE_ON_INTEGRITY_ERROR | Renamed to FLASK_ADMIN_RAISE_ON_INTEGRITY_ERROR | | ADMIN_RAISE_ON_VIEW_EXCEPTION | Renamed to FLASK_ADMIN_RAISE_ON_VIEW_EXCEPTION | New functionality: * Added support for Python <=3.13 * The default query for pymongo can be overridden * Flask async routes are supported * 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. Fixes: * Bootstrap menu icons should show up properly and not duplicated * Redis CLI commands are now case insensitive * SQLAlchemy boolean filters now convert "1" and "0" to Python booleans, which fixes a type coercion issue with psycopg(3). * Jinja templates can now be loaded in StrictUndefined mode. * Remove an implicit dependency on `packaging` * Fixed an error caused by the fallback implementation of `gettext()` (when used in templates) * Fixes compatibility with WTForms 3.2+. * The `Apply` button for filters will show/hide correctly again * Fix `translations_path` attribute when Flask-Admin is used with Flask-Babel * Some translation updates. * Date fields no longer override `widget` if set in `form_args` * “Save and Continue Editing” button no longer discards the “return URL” (allowing to retain filters when switching back to the list) Misc: * Translations and docs have been updated * Various type hinting improvements and fixes

Breaking changes: * Azure Blob Storage SDK has been upgraded from the legacy version (v2) to the latest version (v12). AzureFileAdmin now accept `blob_service_client` rather than `connection_string` to give more flexibility with connection types.

Fixes: Jinja templates can now be loaded in StrictUndefined mode. Remove an implicit dependency on packaging

2.0.0a1 ------- Fixes: * Fixes compatibility with WTForms 3.2+. * The `Apply` button for filters will show/hide correctly again * Fix `translations_path` attribute when Flask-Admin is used with Flask-Babel * Some translation updates. * Date fields no longer override `widget` if set in `form_args` * “Save and Continue Editing” button no longer discards the “return URL” (allowing to retain filters when switching back to the list)

## 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_`. | Config variable name | What’s changed | |----|-----------------------------------------------| | FLASK_ADMIN_SWATCH | Removed; use `Theme(swatch=...)` instead | | FLASK_ADMIN_FLUID_LAYOUT | Removed; use `Theme(fluid=...)` instead | | MAPBOX_MAP_ID | Renamed to FLASK_ADMIN_MAPBOX_MAP_ID | | MAPBOX_SEARCH | Renamed to FLASK_ADMIN_MAPBOX_SEARCH | | MAPBOX_ACCESS_TOKEN | Renamed to FLASK_ADMIN_MAPBOX_ACCESS_TOKEN | | GOOGLE_MAPS_API_KEY | Renamed to FLASK_ADMIN_GOOGLE_MAPS_API_KEY | | DEFAULT_CENTER_LAT | Renamed to FLASK_ADMIN_DEFAULT_CENTER_LAT | | DEFAULT_CENTER_LONG | Renamed to FLASK_ADMIN_DEFAULT_CENTER_LONG | | ADMIN_RAISE_ON_INTEGRITY_ERROR | Renamed to FLASK_ADMIN_RAISE_ON_INTEGRITY_ERROR | | ADMIN_RAISE_ON_VIEW_EXCEPTION | Renamed to FLASK_ADMIN_RAISE_ON_VIEW_EXCEPTION | 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.

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. And various smaller bug fixes and documentation updates.
