Change log

3.2 (unreleased)

  • Fixed a regression where the JavaScript code crashed with an invalid CSS selector when searching for an element to replace.

  • Replaced remaining images with CSS.

  • Continued refactoring the HTML and CSS code for simplicity, continued improving the use of semantic HTML.

  • Stopped caring about prehistoric browsers for good. Started splitting up the JavaScript code to take advantage of JavaScript modules.

  • Continued removing unused CSS.

  • Started running Selenium tests on Travis CI.

  • Added a system check which prevents using django-debug-toolbar without any enabled panels.

  • Added Panel.run_checks for panels to verify the configuration before the application starts.

  • Validate the static file paths specified in STATICFILES_DIRS exist via StaticFilesPanel

  • Introduced prettier to format the frontend code.

  • Started accessing history views using GET requests since they do not change state on the server.

  • Fixed a bug where unsuccessful requests (e.g. network errors) were silently ignored.

3.1 (2020-09-21)

  • Fixed a crash in the history panel when sending an empty JSON POST request.

  • Made make example also set up the database and a superuser account.

  • Added a Makefile target for regenerating the django-debug-toolbar screenshot.

  • Added automatic escaping of panel titles resp. disallowed HTML tags.

  • Removed some CSS

  • Restructured the SQL stats template.

  • Changed command line examples to prefer python -m pip to pip.

3.0 (2020-09-20)

  • Added an .editorconfig file specifying indentation rules etc.

  • Updated the Italian translation.

  • Added support for Django 3.1a1. fetch() and jQuery.ajax requests are now detected by the absence of a Accept: text/html header instead of the jQuery-specific X-Requested-With header on Django 3.1 or better.

  • Pruned unused CSS and removed hacks for ancient browsers.

  • Added the new Panel.scripts property. This property should return a list of JavaScript resources to be loaded in the browser when displaying the panel. Right now, this is used by a single panel, the Timer panel. Third party panels can use this property to add scripts rather then embedding them in the content HTML.

  • Switched from JSHint to ESLint. Added an ESLint job to the Travis CI matrix.

  • Debug toolbar state which is only needed in the JavaScript code now uses localStorage.

  • Updated the code to avoid a few deprecation warnings and resource warnings.

  • Started loading JavaScript as ES6 modules.

  • Added support for cache.touch() when using django-debug-toolbar.

  • Eliminated more inline CSS.

  • Updated tox.ini and Makefile to use isort>=5.

  • Increased RESULTS_CACHE_SIZE to 25 to better support AJAX requests.

  • Fixed the close button CSS by explicitly specifying the box-sizing property.

  • Simplified the isort configuration by taking advantage of isort’s black profile.

  • Added HistoryPanel including support for AJAX requests.

Backwards incompatible changes

  • Loading panel content no longer executes the scripts elements embedded in the HTML. Third party panels that require JavaScript resources should now use the Panel.scripts property.

  • Removed support for end of life Django 1.11. The minimum supported Django is now 2.2.

2.2 (2020-01-31)

  • Removed support for end of life Django 2.0 and 2.1.

  • Added support for Python 3.8.

  • Add locals() option for SQL panel.

  • Added support for Django 3.0.

2.1 (2019-11-12)

  • Changed the Travis CI matrix to run style checks first.

  • Exposed the djdt.init function too.

  • Small improvements to the code to take advantage of newer Django APIs and avoid warnings because of deprecated code.

  • Verified compatibility with the upcoming Django 3.0 (at the time of writing).

2.0 (2019-06-20)

  • Updated StaticFilesPanel to be compatible with Django 3.0.

  • The ProfilingPanel is now enabled but inactive by default.

  • Fixed toggling of table rows in the profiling panel UI.

  • The ProfilingPanel no longer skips remaining panels or middlewares.

  • Improved the installation documentation.

  • Fixed a possible crash in the template panel.

  • Added support for psycopg2 Composed objects.

  • Changed the Jinja2 tests to use Django’s own Jinja2 template backend.

  • Added instrumentation to queries using server side cursors.

  • Too many small improvements and cleanups to list them all.

Backwards incompatible changes

  • Removed support for Python 2.

  • Removed support for Django’s deprecated MIDDLEWARE_CLASSES setting.

  • Restructured Panel to execute more like the new-style Django MIDDLEWARE. The Panel.__init__() method is now passed get_response as the first positional argument. The Panel.process_request() method must now always return a response. Usually this is the response returned by get_response() but the panel may also return a different response as is the case in the RedirectsPanel. Third party panels must adjust to this new architecture. Panel.process_response() and Panel.process_view() have been removed as a result of this change.

The deprecated API, debug_toolbar.panels.DebugPanel, has been removed. Third party panels should use debug_toolbar.panels.Panel instead.

The following deprecated settings have been removed:

  • HIDDEN_STACKTRACE_MODULES

  • HIDE_DJANGO_SQL

  • INTERCEPT_REDIRECTS

  • RESULTS_STORE_SIZE

  • ROOT_TAG_ATTRS

  • TAG

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 accommodate 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 unhashable 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. The JQUERY_URL setting is also removed because it isn’t necessary anymore. If you depend on jQuery, integrate it yourself.

  • 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 bug fixes.

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.

Bug fixes

  • The profiling panel now escapes reported data resulting in valid HTML.

  • Many minor cleanups and bug fixes.

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.

Features

  • 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.

Bug fixes

  • 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)

Bug fixes

  • 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.

Bug fixes

  • 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.

Bug fixes

  • 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

Bug fixes

  • 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 now provides a JavaScript API.

Bug fixes

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

  • The root level logger is preserved.

  • The RESULTS_CACHE_SIZE setting is taken into account.

  • 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.

Bug fixes

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

Bug fixes

  • 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

  • The INTERCEPT_REDIRECTS setting is superseded by the more generic DISABLE_PANELS.

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.
