Change log


1.11 (2018-12-03)

  • Use defer on all <script> tags to avoid blocking HTML parsing, removed inline JavaScript.
  • Stop inlining images in CSS to avoid Content Security Policy errors altogether.
  • Reformatted the code using black.
  • Added the Django mail panel to the list of third-party panels.
  • Convert system check errors to warnings to accomodate exotic configurations.
  • Fixed a crash when explaining raw querysets.
  • Fixed an obscure unicode error with binary data fields.
  • Added MariaDB and Python 3.7 builds to the CI.

1.10.1 (2018-09-11)

  • Fixed a problem where the duplicate query detection breaks for non-hashable query parameters.
  • Added support for structured types when recording SQL.
  • Made Travis CI also run one test no PostgreSQL.
  • Added fallbacks for inline images in CSS.
  • Improved cross-browser compatibility around URLSearchParams usage.
  • Fixed a few typos and redundancies in the documentation, removed mentions of django-debug-toolbar’s jQuery which aren’t accurate anymore.

1.10 (2018-09-06)

  • Removed support for Django < 1.11.
  • Added support and testing for Django 2.1 and Python 3.7. No actual code changes were required.
  • Removed the jQuery dependency. This means that django-debug-toolbar now requires modern browsers with support for fetch, classList etc.
  • Added support for the server timing header.
  • Added a differentiation between similar and duplicate queries. Similar queries are what duplicate queries used to be (same SQL, different parameters).
  • Stopped hiding frames from Django’s contrib apps in stacktraces by default.
  • Lots of small cleanups and bugfixes.

1.9.1 (2017-11-15)

  • Fix erroneous ContentNotRenderedError raised by the redirects panel.

1.9 (2017-11-13)

This version is compatible with Django 2.0 and requires Django 1.8 or later.


  • The profiling panel now escapes reported data resulting in valid HTML.
  • Many minor cleanups and bugfixes.

1.8 (2017-05-05)

This version is compatible with Django 1.11 and requires Django 1.8 or later.

Backwards incompatible changes

  • debug_toolbar.middleware.show_toolbar (the default value of setting SHOW_TOOLBAR_CALLBACK) no longer returns False for AJAX requests. This is to allow reusing the SHOW_TOOLBAR_CALLBACK function to verify access to panel views requested via AJAX. Projects defining a custom SHOW_TOOLBAR_CALLBACK should remove checks for AJAX requests in order to continue to allow access to these panels.


  • New decorator debug_toolbar.decorators.require_show_toolbar prevents unauthorized access to decorated views by checking SHOW_TOOLBAR_CALLBACK every request. Unauthorized access results in a 404.
  • The SKIP_TEMPLATE_PREFIXES setting allows skipping templates in the templates panel. Template-based form widgets’ templates are skipped by default to avoid panel sizes going into hundreds of megabytes of HTML.


  • All views are now decorated with debug_toolbar.decorators.require_show_toolbar preventing unauthorized access.
  • The templates panel now reuses contexts’ pretty printed version which makes the debug toolbar usable again with Django 1.11’s template-based forms rendering.
  • Long SQL statements are now forcibly wrapped to fit on the screen.

1.7 (2017-03-05)


  • Recursive template extension is now understood.
  • Deprecation warnings were fixed.
  • The SQL panel uses HMAC instead of simple hashes to verify that SQL statements have not been changed. Also, the handling of bytes and text for hashing has been hardened. Also, a bug with Python’s division handling has been fixed for improved Python 3 support.
  • An error with django-jinja has been fixed.
  • A few CSS classes have been prefixed with djdt- to avoid conflicting class names.

1.6 (2016-10-05)

The debug toolbar was adopted by jazzband.

Removed features

  • Support for automatic setup has been removed as it was frequently problematic. Installation now requires explicit setup. The DEBUG_TOOLBAR_PATCH_SETTINGS setting has also been removed as it is now unused. See the installation documentation for details.


  • The DebugToolbarMiddleware now also supports Django 1.10’s MIDDLEWARE setting.

1.5 (2016-07-21)

This version is compatible with Django 1.10 and requires Django 1.8 or later.

Support for Python 3.2 is dropped.


  • Restore compatibility with sqlparse ≥ 0.2.0.
  • Add compatibility with Bootstrap 4, Pure CSS, MDL, etc.
  • Improve compatibility with RequireJS / AMD.
  • Improve the UI slightly.
  • Fix invalid (X)HTML.

1.4 (2015-10-06)

This version is compatible with Django 1.9 and requires Django 1.7 or later.

New features


  • Response time for requests of projects with numerous media files has been improved.

1.3 (2015-03-10)

This is the first version compatible with Django 1.8.

New features

  • A new panel is available: Template Profiler.
  • The SHOW_TOOLBAR_CALLBACK accepts a callable.

  • The toolbar handle cannot leave the visible area anymore when the toolbar is collapsed.

  • CSS classes are prefixed with djdt- to prevent name conflicts.
  • The private copy of jQuery no longer registers as an AMD module on sites that load RequireJS.

1.2 (2014-04-25)

New features

  • The JQUERY_URL setting defines where the toolbar loads jQuery from.


  • The toolbar now always loads a private copy of jQuery in order to avoid using an incompatible version. It no longer attemps to integrate with AMD.

    This private copy is available in djdt.jQuery. Third-party panels are encouraged to use it because it should be as stable as the toolbar itself.

1.1 (2014-04-12)

This is the first version compatible with Django 1.7.

New features

  • The SQL panel colors queries depending on the stack level.
  • The Profiler panel allows configuring the maximum depth.


  • Support languages where lowercase and uppercase strings may have different lengths.
  • Allow using cursor as context managers.
  • Make the SQL explain more helpful on SQLite.
  • Various JavaScript improvements.

Deprecated features

1.0 (2013-12-21)

This is the first stable version of the Debug Toolbar!

It includes many new features and performance improvements as well a few backwards-incompatible changes to make the toolbar easier to deploy, use, extend and maintain in the future.

You’re strongly encouraged to review the installation and configuration docs and redo the setup in your projects.

Third-party panels will need to be updated to work with this version.
