The implementations were moved to Werkzeug, Flask's functions become wrappers around Werkzeug to pass some Flask-specific values. cache_timeout is renamed to max_age. SEND_FILE_MAX_AGE_DEFAULT, app.send_file_max_age_default, and app.get_send_file_max_age defaults to None. This tells the browser to use conditional requests rather than a 12 hour cache. attachment_filename is renamed to download_name, and is always sent if a name is known. Deprecate helpers.safe_join in favor of werkzeug.utils.safe_join. Removed most of the send_file tests, they're tested in Werkzeug. In the file upload example, renamed the uploaded_file view to download_file to avoid a common source of confusion. |

Flask
=====
Flask is a lightweight `WSGI`_ web application framework. It is designed
to make getting started quick and easy, with the ability to scale up to
complex applications. It began as a simple wrapper around `Werkzeug`_
and `Jinja`_ and has become one of the most popular Python web
application frameworks.
Flask offers suggestions, but doesn't enforce any dependencies or
project layout. It is up to the developer to choose the tools and
libraries they want to use. There are many extensions provided by the
community that make adding new functionality easy.
