Release notes Django 1.5 release notes

The method Model.save() has a new keyword argument update_fields. By using this argument it is possible to save only a select list of model’s fields. This can be useful for performance reasons or when trying to avoid overwriting concurrent changes.

Release notes Django 1.6 release notes

The Model.save() method now tries to directly UPDATE the database if the instance has a primary key value. Previously SELECT was performed to determine if UPDATE or INSERT were needed.

Release notes Django 1.6 release notes

HTML rendering of model form fields corresponding to ManyToManyField model fields used to get the hardcoded sentence: Hold down “Control”, or “Command” on a Mac, to select more than one.

Release notes Django 1.8 release notes

The following functions will no longer accept a dirs parameter to override TEMPLATE_DIRS in Django 1.10: django.template.loader.get_template() django.template.loader.select_template() django.shortcuts.render() django.shortcuts.render_to_response() The parameter didn’t work consistently across different template loaders and didn’t work for included templates.

Release notes Django 5.0 release notes

The instance argument of the undocumented BaseModelFormSet.save_existing() method is renamed to obj. The undocumented django.contrib.admin.helpers.checkbox is removed. Integer fields are now validated as 64-bit integers on SQLite to match the behavior of sqlite3.

This section describes changes that may be needed in third-party database backends. The DatabaseOperations.time_trunc_sql() method is added to support TimeField truncation.

Release notes Django 1.3 release notes

When using managed transactions – that is, anything but the default autocommit mode – it is important when a transaction is marked as “dirty”.

Release notes Django 1.4 release notes

Django’s comments has historically supported excluding the comments of a special user group, but we’ve never documented the feature properly and didn’t enforce the exclusion in other parts of the app such as the template tags.

Release notes Django 1.6 release notes

When you are running raw SQL queries through the cursor.execute method, the rule about doubling percent literals (%) inside the query has been unified. Past behavior depended on the database backend.

Release notes Django 1.8 release notes

The django.db.models.sql.aggregates and django.contrib.gis.db.models.sql.aggregates modules (both private API), have been deprecated as django.db.models.aggregates and django.contrib.gis.db.models.aggregates are now also responsible for SQL generation. The old modules will be removed in Django 1.10.

Release notes Django 1.8 release notes

The return type of get_template() has changed in Django 1.8: instead of a django.template.Template, it returns a Template instance whose exact type depends on which backend loaded it.

Release notes Django 2.0 release notes

This section describes changes that may be needed in third-party database backends. The DatabaseOperations.datetime_cast_date_sql(), datetime_cast_time_sql(), datetime_trunc_sql(), datetime_extract_sql(), and date_interval_sql() methods now return only the SQL to perform the operation instead of SQL and a list of parameters.

Django now supports a fully asynchronous request path, including: Asynchronous views Asynchronous middleware Asynchronous tests and test client To get started with async views, you need to declare a view using async def: All asynchronous features are supported whether you …

Release notes Django 4.0 release notes

New QuerySet.contains(obj) method returns whether the queryset contains the given object. This tries to perform the query in the simplest and fastest way possible.

Release notes Django 4.2.6 release notes

Fixed a regression in Django 4.2.5 where overriding the deprecated DEFAULT_FILE_STORAGE and STATICFILES_STORAGE settings in tests caused the main STORAGES to mutate (#34821).

Release notes Django 5.1.2 release notes

Fixed a regression in Django 5.1 that caused a crash when using the PostgreSQL lookup trigram_similar on output fields from Concat (#35732).

Release notes Django 1.10 release notes

The repr() of a QuerySet is wrapped in <QuerySet > to disambiguate it from a plain list when debugging. utils.version.get_version() returns PEP 440 compliant release candidate versions (e.g. ‘1.10rc1’ instead of ‘1.10c1’).
