Change Log


  • Fix issue with the immutable file test when running behind a CDN which rewrites paths (thanks @lskillen).


  • Support the new immutable Cache-Control header. This gives better caching behaviour for immutable resources than simply setting a large max age.


  • Gracefully handle invalid byte sequences in URLs.
  • Gracefully handle filenames which are too long for the filesystem.
  • Send correct Content-Type for Adobe’s crossdomain.xml files.


  • Convert any config values supplied as byte strings to text to avoid runtime encoding errors when encountering non-ASCII filenames.


  • Handle non-ASCII URLs correctly when using the integration.
  • Fix exception triggered when a static files “finder” returned a directory rather than a file.


  • Add support for the new-style middleware classes introduced in Django 1.10. The same WhiteNoiseMiddleware class can now be used in either the old MIDDLEWARE_CLASSES list or the new MIDDLEWARE list.
  • Fixed a bug where incorrect Content-Type headers were being sent on 304 Not Modified responses (thanks @oppianmatt).
  • Return Vary and Cache-Control headers on 304 responses, as specified by the RFC.


  • Add new WHITENOISE_STATIC_PREFIX setting to give flexibility in supporting non-standard deployment configurations e.g. serving the application somewhere other than the domain root.
  • Fix bytes/unicode bug when running with Django 1.10 on Python 2.7



The latest version of WhiteNoise contains some small breaking changes. Most users will be able to upgrade without any problems, but some less-used APIs have been modified:

  • The CLI compression utility has moved from python -m whitenoise.gzip to python -m whitenoise.compress.
  • The now redundant gzipstatic management command has been removed.
  • WhiteNoise no longer uses the system mimetypes files, so if you are serving particularly obscure filetypes you may need to add their mimetypes explicitly using the new mimetypes setting.
  • Older versions of Django (1.4-1.7) and Python (2.6) are no longer supported. If you need support for these platforms you can continue to use WhiteNoise 2.x.
  • The whitenoise.django.GzipManifestStaticFilesStorage storage backend has been moved to The old import path will continue to work for now, but users are encouraged to update their code to use the new path.

Simpler, cleaner Django middleware integration

WhiteNoise can now integrate with Django by adding a single line to MIDDLEWARE_CLASSES without any need to edit This also means that WhiteNoise plays nicely with other middleware classes such as SecurityMiddleware, and that it is fully compatible with the new Channels system. See the updated documentation for details.

Brotli compression support

Brotli is the modern, more efficient alternative to gzip for HTTP compression. To benefit from smaller files and faster page loads, just install the brotlipy library, update your requirements.txt and WhiteNoise will take care of the rest. See the documentation for details.

Simpler customisation

It’s now possible to add custom headers to WhiteNoise without needing to create a subclass, using the new add_headers_function setting.

Use WhiteNoise in development with Django

There’s now an option to force Django to use WhiteNoise in development, rather than its own static file handling. This results in more consistent behaviour between development and production environments and fewer opportunities for bugs and surprises. See the documentation for details.

Improved mimetype handling

WhiteNoise now ships with its own mimetype definitions (based on those shipped with nginx) instead of relying on the system ones, which can vary between environments. There is a new mimetypes configuration option which makes it easy to add additional type definitions if needed.


A big thank-you to Ed Morley and Tim Graham for their contributions to this release.


  • Rebuild with latest version of wheel to get extras_require support.


  • Add missing argparse dependency for Python 2.6 (thanks @movermeyer)).


  • Report path on MissingFileError (thanks @ezheidtmann).


  • Add __version__ attribute.


  • More helpful error message when STATIC_URL is set to the root of a domain (thanks @dominicrodger).


  • Add support for Python 2.6.
  • Add a more helpful error message when attempting to import DjangoWhiteNoise before DJANGO_SETTINGS_MODULE is defined.


  • Add an autorefresh mode which picks up changes to static files made after application startup (for use in development).
  • Add a use_finders mode for DjangoWhiteNoise which finds files in their original directories without needing them collected in STATIC_ROOT (for use in development). Note, this is only useful if you don’t want to use Django’s default runserver behaviour.
  • Remove the follow_symlinks argument from add_files and now always follow symlinks.
  • Support extra mimetypes which Python doesn’t know about by default (including .woff2 format)
  • Some internal refactoring. Note, if you subclass WhiteNoise to add custom behaviour you may need to make some small changes to your code.


  • Fix unhelpful exception inside make_helpful_exception on Python 3 (thanks @abbottc).


  • Fix error when attempting to gzip empty files (thanks @ryanrhee).


  • Don’t attempt to gzip .woff files as they’re already compressed.
  • Base decision to gzip on compression ratio achieved, so we don’t incur gzip overhead just to save a few bytes.
  • More helpful error message from collectstatic if CSS files reference missing assets.


  • Fix bug in Last Modified date handling (thanks to Atsushi Odagiri for spotting).


  • Set the default max_age parameter in base class to be what the docs claimed it was.


  • Fix path-to-URL conversion for Windows.
  • Remove cruft from packaging manifest.


  • First stable release.
