🚀 Django 6.1: Loading related data on demand, cascading deletion handled by the database, and a new email configuration.

The release was made on August 5th. Three major changes:

1. New Field Loading Modes 📂

FETCH_PEERS retrieves data for related objects from the same QuerySet when accessing an un-loaded field. This helps combat the N+1 problem:

from django.db import models

books = Book.objects.fetch_mode(models.FETCH_PEERS)

for book in books:
    print(book.author.name)

In this example, Django executes two queries: one for the books and one for their authors.

The FETCH_RAISE mode raises an exception instead of performing an implicit query – useful for detecting unexpected database accesses.

2. Deletion at the Database Level 🗑

For ForeignKey.on_delete, the options DB_CASCADE, DB_SET_NULL, and DB_SET_DEFAULT are now available. The logic is handled directly by the database using SQL ON DELETE.

Note: DB_CASCADE does not trigger pre_delete and post_delete signals.

3. Multiple Email Backends 📧

The MAILERS configuration allows you to define different connections using a dictionary, and you can select the desired connection when sending emails using the using parameter.

Before upgrading, check your database versions: you need PostgreSQL 15+, MySQL 8.4+, MariaDB 10.11+, or SQLite 3.37+.
