Added protection against division by 0 in timer.js
Added Profiling panel setting
PROFILER_THRESHOLD_RATIOto give users better control over how many function calls are included. A higher value will include more data, but increase render time.
Update Profiling panel to include try to always include user code. This code is more important to developers than dependency code.
Highlight the project function calls in the profiling panel.
Added Profiling panel setting

Properly implemented tracking and display of PostgreSQL transactions.
Removed third party panels which have been archived on GitHub.
Added Django 4.1b1 to the CI matrix.
Stopped crashing when
request.POSTare neither dictionaries nor

Fixed the cache panel to work correctly in the presence of concurrency by avoiding the use of signals.
Reworked the cache panel instrumentation mechanism to monkey patch methods on the cache instances directly instead of replacing cache instances with wrapper classes.
debug_toolbar.panels.Panel.ready()class method that panels can override to perform any initialization or instrumentation that needs to be done unconditionally at startup time.

tox -e docs html.
Stayed on top of pre-commit hook updates.
debug_toolbar.utils.tidy_stacktrace()functions are deprecated in favor of the new

/__debug__/while the documentation indicates it’s not required.
Moved CI to GitHub Actions: https://github.com/jazzband/django-debug-toolbar/actions

Backwards incompatible changes¶
Removed support for end of life Django 1.11. The minimum supported Django is now 2.2.

Too many small improvements and cleanups to list them all.
Backwards incompatible changes¶
Removed support for Python 2.
Removed support for Django’s deprecated
debug_toolbar.panels.Panelto execute more like the new-style Django MIDDLEWARE. The
Panel.__init__()method is now passed
get_responseas the first positional argument. The
debug_toolbar.panels.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_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
The following deprecated settings have been removed:
Stop inlining images in CSS to avoid Content Security Policy errors altogether.

Removed support for Django < 1.11.
Added support and testing for Django 2.1 and Python 3.7. No actual code changes were required.

JQUERY_URLsetting 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.
ContentNotRenderedErrorraised by the redirects panel.
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 bug fixes.
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
Falsefor AJAX requests. This is to allow reusing the
SHOW_TOOLBAR_CALLBACKfunction to verify access to panel views requested via AJAX. Projects defining a custom
SHOW_TOOLBAR_CALLBACKshould remove checks for AJAX requests in order to continue to allow access to these panels.
debug_toolbar.decorators.require_show_toolbarprevents unauthorized access to decorated views by checking
SHOW_TOOLBAR_CALLBACKevery request. Unauthorized access results in a 404.
SKIP_TEMPLATE_PREFIXESsetting 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_toolbarpreventing 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.
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.
The debug toolbar was adopted by Jazzband.
Support for automatic setup has been removed as it was frequently problematic. Installation now requires explicit setup. The
DEBUG_TOOLBAR_PATCH_SETTINGSsetting has also been removed as it is now unused. See the installation documentation for details.
DebugToolbarMiddlewarenow also supports Django 1.10’s
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.

Improve the UI slightly.
Fix invalid (X)HTML.
This version is compatible with Django 1.9 and requires Django 1.7 or later.
New panel method
debug_toolbar.panels.Panel.generate_stats()allows panels to only record stats when the toolbar is going to be inserted into the response.
Response time for requests of projects with numerous media files has been improved.
This is the first version compatible with Django 1.8.
A new panel is available: Template Profiler.
SHOW_TOOLBAR_CALLBACKaccepts a callable.
The toolbar handle cannot leave the visible area anymore when the toolbar is collapsed.
The root level logger is preserved.
RESULTS_CACHE_SIZEsetting 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.
JQUERY_URLsetting 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 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.
This is the first version compatible with Django 1.7.
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.
INTERCEPT_REDIRECTSsetting is superseded by the more generic
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.
