Reference for Database Migrations
'''''''''''''''''''''''''''''''''

Here's the list of all the Database Migrations that are executed via when you run ``airflow fab-db migrate``.

.. warning::

   Those migration details are mostly used here to make the users aware when and what kind of migrations
   will be executed during migrations between specific FAB provider versions. The intention here is that the
   "DB conscious" users might perform an analysis on the migrations and draw conclusions about the impact
   of the migrations on their Airflow database.

 .. This table is automatically updated by prek hook: ``scripts/ci/prek/migration_reference.py``
 .. All table elements are scraped from migration files
