This new method will pick out any environment variables with a certain
prefix and place them into the config named without the prefix. This
makes it easy to use environment variables to configure the app as is
now more popular than when Flask started.
The prefix should ensure that the environment isn't polluted and the
config isn't polluted by environment variables.
I've followed the dynaconf convention of trying to parse the
environment variable and then falling back to the raw value if parsing
fails.
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.
TOML is a very popular format now, and is taking hold in the Python
ecosystem via pyproject.toml (among others). This allows toml config
files via,
app.config.from_file("config.toml", toml.loads)
it also allows for any other file format whereby there is a loader
that takes a string and returns a mapping.

test allowing subdomains as well as ips
