# Django 6.0 release notes

December 3, 2025

Welcome to Django 6.0!

These release notes cover the new features, as well as some backwards incompatible changes you should be aware of when upgrading from Django 5.2 or earlier. We’ve begun the deprecation process for some features.

See the Django를 최신 버전으로 업그레이드하는 방법 guide if you’re updating an existing project.

## 파이썬 호환성

Django 6.0 supports Python 3.12, 3.13, and 3.14. We highly recommend, and only officially support, the latest release of each series.

The Django 5.2.x series is the last to support Python 3.10 and 3.11.

## Third-party library support for older versions of Django

Following the release of Django 6.0, we suggest that third-party app authors drop support for all versions of Django prior to 5.2. At that time, you should be able to run your package’s tests using `python -Wd` so that deprecation warnings appear. After making the deprecation warning fixes, your app should be compatible with Django 6.0.

## What’s new in Django 6.0

### Content Security Policy support

Built-in support for the Content Security Policy (CSP) standard is now available, making it easier to protect web applications against content injection attacks such as cross-site scripting (XSS). CSP allows declaring trusted sources of content by giving browsers strict rules about which scripts, styles, images, or other resources can be loaded.

CSP policies can now be enforced or monitored directly using built-in tools: headers are added via the `ContentSecurityPolicyMiddleware`, nonces are supported through the `csp()` context processor, and policies are configured using the `SECURE_CSP` and `SECURE_CSP_REPORT_ONLY` settings.

These settings accept Python dictionaries and support Django-provided constants for clarity and safety. For example:

    from django.utils.csp import CSP

    SECURE_CSP = {
        "default-src": [CSP.SELF],
        "script-src": [CSP.SELF, CSP.NONCE],
        "img-src": [CSP.SELF, "https:"],
    }

The resulting `Content-Security-Policy` header would be set to:

    default-src 'self'; script-src 'self' 'nonce-SECRET'; img-src 'self' https:

To get started, follow the CSP how-to guide. For in-depth guidance, see the CSP security overview and the reference docs, which include details about decorators to override or disable policies on a per-view basis.

### Template Partials

The Django Template Language now supports template partials, making it easier to encapsulate and reuse small named fragments within a template file. The new tags `{% partialdef %}` and `{% partial %}` define a partial and render it, respectively.

Partials can also be referenced using the `template_name#partial_name` syntax with `get_template()`, `render()`, `{% include %}`, and other template-loading tools, enabling more modular and maintainable templates without needing to split components into separate files.

A migration guide is available if you’re updating from the django-template-partials third-party package.

### Background Tasks

Django now includes a built-in Tasks framework for running code outside the HTTP request–response cycle. This enables offloading work, such as sending emails or processing data, to background workers.

The framework provides task definition, validation, queuing, and result handling. Django guarantees consistent behavior for creating and managing tasks, while the responsibility for running them continues to belong to external worker processes.

Tasks are defined using the `task()` decorator:

    from django.core.mail import send_mail
    from django.tasks import task

    @task
    def email_users(emails, subject, message):
        return send_mail(subject, message, None, emails)

Once defined, tasks can be enqueued through a configured backend:

    email_users.enqueue(
        emails=["user@example.com"],
        subject="You have a message",
        message="Hello there!",
    )

Backends are configured via the `TASKS` setting. The two built-in backends included in this release are primarily intended for development and testing.

Django handles task creation and queuing, but does not provide a worker mechanism to run tasks. Execution must be managed by external infrastructure, such as a separate process or service.

See Django’s Tasks framework for an overview and the Tasks reference for API details.

### Adoption of Python’s modern email API

Email handling in Django now uses Python’s modern email API, introduced in Python 3.6. This API, centered around the `email.message.EmailMessage` class, offers a cleaner and Unicode-friendly interface for composing and sending emails. It replaces use of Python’s older legacy (`Compat32`) API, which relied on lower-level MIME classes (from `email.mime`) and required more manual handling of message structure and encoding.

Notably, the return type of the `EmailMessage.message()` method is now an instance of Python’s `email.message.EmailMessage`. This supports the same API as the previous `SafeMIMEText` and `SafeMIMEMultipart` return types, but is not an instance of those now-deprecated classes.

### Minor features

#### `django.contrib.admin`

- The Font Awesome Free icon set (version 6.7.2) is now used for the admin interface icons.

- The new `AdminSite.password_change_form` attribute allows customizing the form used in the admin site password change view.

- Message levels `messages.DEBUG` and `messages.INFO` now have distinct icons and CSS styling. Previously, both levels shared the same appearance as `messages.SUCCESS`. Given that `ModelAdmin.message_user()` uses `messages.INFO` by default, set the level to `messages.SUCCESS` to keep the previous icon and styling.

#### `django.contrib.auth`

- The default iteration count for the PBKDF2 password hasher is increased from 1,000,000 to 1,200,000.

#### `django.contrib.gis`

- The new `GEOSGeometry.hasm` property checks whether the geometry has the M dimension.

- The new `Rotate` database function rotates a geometry by a specified angle around the origin or a specified point.

- The new `BaseGeometryWidget.base_layer` attribute allows specifying a JavaScript map base layer, enabling customization of map tile providers.

- `coveredby` and `isvalid` lookups, `Collect` aggregation, and `GeoHash` and `IsValid` database functions are now supported on MariaDB 12.0.1+.

- The new `geom_type` lookup and `GeometryType()` database function allow filtering geometries by their types.

- Widgets from `django.contrib.gis.forms.widgets` now render without inline JavaScript in templates. If you have customized any geometry widgets or their templates, you may need to update them to match the new layout.

#### `django.contrib.postgres`

- The new `Lexeme` expression for full text search provides fine-grained control over search terms. `Lexeme` objects automatically escape their input and support logical combination operators (`&`, `|`, `~`), prefix matching, and term weighting.

- Model fields, indexes, and constraints from `django.contrib.postgres` now include system checks to verify that `django.contrib.postgres` is an installed app.

- The `CreateExtension`, `BloomExtension`, `BtreeGinExtension`, `BtreeGistExtension`, `CITextExtension`, `CryptoExtension`, `HStoreExtension`, `TrigramExtension`, and `UnaccentExtension` operations now support the optional `hints` parameter. This allows providing database hints to database routers to assist them in making routing decisions.

#### `django.contrib.staticfiles`

- `ManifestStaticFilesStorage` now ensures consistent path ordering in manifest files, making them more reproducible and reducing unnecessary diffs.

- The `collectstatic` command now reports only a summary for skipped files (and for deleted files when using `--clear`) at `--verbosity` 1. To see per-file details for either case, set `--verbosity` to 2 or higher.

#### 이메일

- The new `policy` argument for `EmailMessage.message()` allows specifying the email policy, the set of rules for updating and serializing the representation of the message. Defaults to `email.policy.default`.

- `EmailMessage.attach()` now accepts a `MIMEPart` object from Python’s modern email API.

#### 국제화

- Added support and translations for the Haitian Creole language.

#### Management Commands

- The `startproject` and `startapp` commands now create the custom target directory if it doesn’t exist.

- Common utilities, such as `django.conf.settings`, are now automatically imported to the `shell` by default.

#### 마이그레이션

- Squashed migrations can now themselves be squashed before being transitioned to normal migrations.

- Migrations now support serialization of `zoneinfo.ZoneInfo` instances.

- Serialization of deconstructible objects now supports keyword arguments with names that are not valid Python identifiers.

#### 모델

- Constraints now implement a `check()` method that is already registered with the check framework.

- The new `order_by` argument for `Aggregate` allows specifying the ordering of the elements in the result.

- The new `Aggregate.allow_order_by` class attribute determines whether the aggregate function allows passing an `order_by` keyword argument.

- The new `StringAgg` aggregate returns the input values concatenated into a string, separated by the `delimiter` string. This aggregate was previously supported only for PostgreSQL.

- The `save()` method now raises a specialized `Model.NotUpdated` exception, when a forced update results in no affected rows, instead of a generic `django.db.DatabaseError`.

- `QuerySet.raw()` now supports models with a `CompositePrimaryKey`.

- Subqueries returning a `CompositePrimaryKey` can now be used as the target of lookups other than `__in`, such as `__exact`.

- `JSONField` now supports negative array indexing on SQLite.

- The new `AnyValue` aggregate returns an arbitrary value from the non-null input values. This is supported on SQLite, MySQL, Oracle, and PostgreSQL 16+.

- `GeneratedField`s and fields assigned expressions are now refreshed from the database after `save()` on backends that support the `RETURNING` clause (SQLite, PostgreSQL, and Oracle). On backends that don’t support it (MySQL and MariaDB), the fields are marked as deferred to trigger a refresh on subsequent accesses.

- Using a ForeignObject with multiple `from_fields` in Model indexes, constraints, or `unique_together` now emits a system check error.

#### 페이지네이션

- The new `AsyncPaginator` and `AsyncPage` provide async implementations of `Paginator` and `Page` respectively.

#### Requests and Responses

- Multiple `Cookie` headers are now supported for HTTP/2 requests when running with ASGI.

#### 템플릿

- The new variable `forloop.length` is now available within a `for` loop.

- The `querystring` template tag now consistently prefixes the returned query string with a `?`, ensuring reliable link generation behavior.

- The `querystring` template tag now accepts multiple positional arguments, which must be mappings, such as `QueryDict` or `dict`.

#### Tests

- The `DiscoverRunner` now supports parallel test execution on systems using the `forkserver` `multiprocessing` start method.

## Backwards incompatible changes in 6.0

### Database backend API

This section describes changes that may be needed in third-party database backends.

- `BaseDatabaseSchemaEditor` and PostgreSQL backends no longer use `CASCADE` when dropping a column.

- `DatabaseOperations.return_insert_columns()` and `DatabaseOperations.fetch_returned_insert_rows()` methods are renamed to `returning_columns()` and `fetch_returned_rows()`, respectively, to denote they can be used in the context of `UPDATE … RETURNING` statements as well as `INSERT … RETURNING`.

- The `DatabaseOperations.fetch_returned_insert_columns()` method is removed and the `fetch_returned_rows()` method replacing `fetch_returned_insert_rows()` expects both a `cursor` and `returning_params` to be provided, just like `fetch_returned_insert_columns()` did.

- If the database supports `UPDATE … RETURNING` statements, backends can set `DatabaseFeatures.can_return_rows_from_update=True`.

### Dropped support for MariaDB 10.5

Upstream support for MariaDB 10.5 ends in June 2025. Django 6.0 supports MariaDB 10.6 and higher.

### Dropped support for Python < 3.12

Because Python 3.12 is now the minimum supported version for Django, any optional dependencies must also meet that requirement. The following versions of each library are the first to add or confirm compatibility with Python 3.12:

- `aiosmtpd` 1.4.5

- `argon2-cffi` 23.1.0

- `bcrypt` 4.1.1

- `docutils` 0.22

- `geoip2` 4.8.0

- `Pillow` 10.1.0

- `mysqlclient` 2.2.1

- `numpy` 1.26.0

- `PyYAML` 6.0.2

- `psycopg` 3.1.12

- `psycopg2` 2.9.9

- `redis-py` 5.1.0

- `selenium` 4.23.0

- `sqlparse` 0.5.0

- `tblib` 3.0.0

### 이메일

- The undocumented `mixed_subtype` and `alternative_subtype` properties of `EmailMessage` and `EmailMultiAlternatives` are no longer supported.

- The undocumented `encoding` property of `EmailMessage` no longer supports Python legacy `email.charset.Charset` objects.

- As the internal implementations of `EmailMessage` and `EmailMultiAlternatives` have changed significantly, closely examine any custom subclasses that rely on overriding undocumented, internal underscore methods.

### `DEFAULT_AUTO_FIELD` setting now defaults to `BigAutoField`

Since Django 3.2, when the `DEFAULT_AUTO_FIELD` setting was added, the default `startproject` template’s `settings.py` contained:

    DEFAULT_AUTO_FIELD = "django.db.models.BigAutoField"

and the default `startapp` template’s `AppConfig` contained:

    default_auto_field = "django.db.models.BigAutoField"

At that time, the default value of `DEFAULT_AUTO_FIELD` remained `django.db.models.AutoField` for backwards compatibility.

In Django 6.0, `DEFAULT_AUTO_FIELD` now defaults to `django.db.models.BigAutoField` and the aforementioned lines in the project and app templates are removed.

Most projects shouldn’t be affected, since Django 3.2 has raised the system check warning models.W042 for projects that don’t set `DEFAULT_AUTO_FIELD`.

If you haven’t dealt with this warning by now, add `DEFAULT_AUTO_FIELD = 'django.db.models.AutoField'` to your project’s settings, or `default_auto_field = 'django.db.models.AutoField'` to an app’s `AppConfig`, as needed.

### Custom ORM expressions should return params as a tuple

Prior to Django 6.0, custom lookups and custom expressions implementing the `as_sql()` method (and its supporting methods `process_lhs()` and `process_rhs()`) were allowed to return a sequence of params in either a list or a tuple. To address the interoperability problems that resulted, the second return element of the `as_sql()` method should now be a tuple:

    def as_sql(self, compiler, connection) -> tuple[str, tuple]: ...

If your custom expressions support multiple versions of Django, you should adjust any pre-processing of parameters to be resilient against either tuples or lists. For instance, prefer unpacking like this:

    params = (*lhs_params, *rhs_params)

### 기타

- The JSON serializer now writes a newline at the end of the output, even without the `indent` option set.

- The minimum supported version of `asgiref` is increased from 3.8.1 to 3.9.1.

- `Field.pre_save()` may now be called more than once when saving model instances, so custom implementations should be idempotent and free of side effects.

## Features deprecated in 6.0

### Positional arguments in `django.core.mail` APIs

`django.core.mail` APIs now require keyword arguments for less commonly used parameters. Using positional arguments for these now emits a deprecation warning and will raise a `TypeError` when the deprecation period ends:

- All optional parameters (`fail_silently` and later) must be passed as keyword arguments to `get_connection()`, `mail_admins()`, `mail_managers()`, `send_mail()`, and `send_mass_mail()`.

- All parameters must be passed as keyword arguments when creating an `EmailMessage` or `EmailMultiAlternatives` instance, except for the first four (`subject`, `body`, `from_email`, and `to`), which may still be passed either as positional or keyword arguments.

### 기타

- `BaseDatabaseCreation.create_test_db(serialize)` is deprecated. Use `serialize_db_to_string()` instead.

- The PostgreSQL `StringAgg` class is deprecated in favor of the generally available `StringAgg` class.

- Passing a string to the `delimiter` argument of the (deprecated) PostgreSQL `StringAgg` class is deprecated. Use a `Value` or expression instead to prepare for compatibility with the generally available `StringAgg` class.

- The PostgreSQL `OrderableAggMixin` is deprecated in favor of the `order_by` attribute now available on the `Aggregate` class.

- The default protocol in `urlize` and `urlizetrunc` will change from HTTP to HTTPS in Django 7.0. Set the transitional setting `URLIZE_ASSUME_HTTPS` to `True` to opt into assuming HTTPS during the Django 6.x release cycle.

- The `URLIZE_ASSUME_HTTPS` transitional setting is deprecated.

- Setting `ADMINS` or `MANAGERS` to a list of (name, address) tuples is deprecated. Set to a list of email address strings instead. Django never used the name portion. To include a name, format the address string as `'"Name" <address>'` or use Python’s `email.utils.formataddr()`.

- Support for the `orphans` argument being larger than or equal to the `per_page` argument of `django.core.paginator.Paginator` and `django.core.paginator.AsyncPaginator` is deprecated.

- Using a percent sign in a column alias or annotation is deprecated.

- Support for passing Python’s legacy email `MIMEBase` object to `EmailMessage.attach()` (or including one in the message’s `attachments` list) is deprecated. For complex attachments requiring additional headers or parameters, switch to the modern email API’s `MIMEPart`.

- The `django.core.mail.BadHeaderError` exception is deprecated. Python’s modern email raises a `ValueError` for email headers containing prohibited characters.

- The `django.core.mail.SafeMIMEText` and `SafeMIMEMultipart` classes are deprecated.

- The undocumented `django.core.mail.forbid_multi_line_headers()` and `django.core.mail.message.sanitize_address()` functions are deprecated.
