There are over a year's worth of changes in this release. Many features have been improved or changed. Read the changelog to understand how your project's code will be affected.
JSON Security Fix
Flask previously decoded incoming JSON bytes using the content type of the request. Although JSON should only be encoded as UTF-8, Flask was more lenient. However, Python includes non-text related encodings that could result in unexpected memory use by a request.
Flask will now detect the encoding of incoming JSON data as one of the supported UTF encodings, and will not allow arbitrary encodings from the request.
This is a repackage of 0.12.3 to fix an issue with how the package was built.
Upgrade
Upgrade from PyPI with pip. Use a version identifier if you want to stay at 0.12:
pip install -U 'Flask~=0.12.4'
0.12.3
This release includes an important security fix for JSON and a minor backport for CLI support in PyCharm. It is provided for projects that cannot update to Flask 1.0 immediately. See the 1.0 announcement and update to it instead if possible.

Skip :meth:app.run <Flask.run> when a Flask application is run
from the command line. This avoids some behavior that was confusing
to debug.
Change the default for :data:JSONIFY_PRETTYPRINT_REGULAR to
False. :func:~json.jsonify returns a compact format by
default, and an indented format in debug mode. :pr:2193
:meth:Flask.__init__ <Flask> accepts the host_matching
argument and sets it on :attr:~Flask.url_map. :issue:1559
:meth:Flask.__init__ <Flask> accepts the static_host argument
and passes it as the host argument when defining the static
route. :issue:1559
:func:send_file supports Unicode in attachment_filename.
:pr:2223
Pass _scheme argument from :func:url_for to
:meth:~Flask.handle_url_build_error. :pr:2017
:meth:~Flask.add_url_rule accepts the
provide_automatic_options argument to disable adding the
OPTIONS method. :pr:1489
:class:~views.MethodView subclasses inherit method handlers from
base classes. :pr:1936
Errors caused while opening the session at the beginning of the
request are handled by the app's error handlers. :pr:2254
Blueprints gained :attr:~Blueprint.json_encoder and
:attr:~Blueprint.json_decoder attributes to override the app's
encoder and decoder. :pr:1898
:meth:Flask.make_response raises TypeError instead of
ValueError for bad response types. The error messages have been
improved to describe why the type is invalid. :pr:2256
Add routes CLI command to output routes registered on the
application. :pr:2259
Show warning when session cookie domain is a bare hostname or an IP
address, as these may not behave properly in some browsers, such as
Chrome. :pr:2282
Allow IP address as exact session cookie domain. :pr:2282
SESSION_COOKIE_DOMAIN is set if it is detected through
SERVER_NAME. :pr:2282
Auto-detect zero-argument app factory called create_app or
make_app from FLASK_APP. :pr:2297
Factory functions are not required to take a script_info
parameter to work with the flask command. If they take a single
parameter or a parameter named script_info, the
