Flask 0.10.1 -> 0.12.2


Released on May 16 2017

  • Fix a bug in safe_join on Windows.


Bugfix release, released on March 31st 2017

  • Prevent flask run from showing a NoAppException when an ImportError occurs
    within the imported application module.
  • Fix encoding behavior of app.config.from_pyfile for Python 3. Fix
  • Use the SERVER_NAME config if it is present as default values for 2109, 2152
  • Call ctx.auto_pop with the exception object instead of None, in the
    event that a BaseException such as KeyboardInterrupt is raised in a
    request handler.


Released on December 21st 2016, codename Punsch.

  • the cli command now responds to --version.
  • Mimetype guessing and ETag generation for file-like objects in send_file
    has been removed, as per issue 104. See pull request 1849.
  • Mimetype guessing in send_file now fails loudly and doesn't fall back to
    application/octet-stream. See pull request 1988.
  • Make flask.safe_join able to join multiple paths like os.path.join
    (pull request 1730).
  • Revert a behavior change that made the dev server crash instead of returning
    a Internal Server Error (pull request 2006).
  • Correctly invoke response handlers for both regular request dispatching as
    well as error handlers.
  • Disable logger propagation by default for the app logger.
  • Add support for range requests in send_file.
  • app.test_client includes preset default environment, which can now be
    directly set, instead of per client.get.


Bugfix release, unreleased

  • Fix crash when running under PyPy3, see pull request 1814.


Bugfix release, released on June 7th 2016.

  • Fixed a bug that prevented FLASK_APP=foobar/ from working. See
    pull request 1872.


Released on May 29th 2016, codename Absinthe.

  • Added support to serializing top-level arrays to :func:flask.jsonify. This
    introduces a security risk in ancient browsers. See
    :ref:json-security for details.
  • Added before_render_template signal.
  • Added **kwargs to :meth:flask.Test.test_client to support passing
    additional keyword arguments to the constructor of
  • Added SESSION_REFRESH_EACH_REQUEST config key that controls the
    set-cookie behavior. If set to True a permanent session will be
    refreshed each request and get their lifetime extended, if set to
    False it will only be modified if the session actually modifies.
    Non permanent sessions are not affected by this and will always
    expire if the browser window closes.
  • Made Flask support custom JSON mimetypes for incoming data.
  • Added support for returning tuples in the form (response, headers)
    from a view function.
  • Added :meth:flask.Config.from_json.
  • Added :attr:flask.Flask.config_class.
  • Added :meth:flask.Config.get_namespace.
  • Templates are no longer automatically reloaded outside of debug mode. This
    can be configured with the new TEMPLATES_AUTO_RELOAD config key.
  • Added a workaround for a limitation in Python 3.3's namespace loader.
  • Added support for explicit root paths when using Python 3.3's namespace
  • Added :command:flask and the flask.cli module to start the local
    debug server through the click CLI system. This is recommended over the old method as it works faster and more reliable due to a
    different design and also replaces Flask-Script.
  • Error handlers that match specific classes are now checked first,
    thereby allowing catching exceptions that are subclasses of HTTP
    exceptions (in werkzeug.exceptions). This makes it possible
    for an extension author to create exceptions that will by default
    result in the HTTP error of their choosing, but may be caught with
    a custom error handler if desired.
  • Added :meth:flask.Config.from_mapping.
  • Flask will now log by default even if debug is disabled. The log format is
    now hardcoded but the default log handling can be disabled through the
    LOGGER_HANDLER_POLICY configuration key.
  • Removed deprecated module functionality.
  • Added the EXPLAIN_TEMPLATE_LOADING config flag which when enabled will
    instruct Flask to explain how it locates templates. This should help
    users debug when the wrong templates are loaded.
  • Enforce blueprint handling in the order they were registered for template
  • Ported test suite to py.test.
  • Deprecated request.json in favour of request.get_json().
  • Add "pretty" and "compressed" separators definitions in jsonify() method.
    Reduces JSON response size when JSONIFY_PRETTYPRINT_REGULAR=False by removing
    unnecessary white space included by default after separators.
  • JSON responses are now terminated with a newline character, because it is a
    convention that UNIX text files end with a newline and some clients don't
    deal well when this newline is missing. See
    pallets/flask#1262 -- this came up originally as a
    part of postmanlabs/httpbin#168
  • The automatically provided OPTIONS method is now correctly disabled if
    the user registered an overriding rule with the lowercase-version
    options (issue 1288).
  • flask.json.jsonify now supports the type (pull request
  • Don't leak exception info of already catched exceptions to context teardown
    handlers (pull request 1393).
  • Allow custom Jinja environment subclasses (pull request 1422).
  • flask.g now has pop() and setdefault methods.
  • Turn on autoescape for flask.templating.render_template_string by default
    (pull request 1515).
  • flask.ext is now deprecated (pull request 1484).
  • send_from_directory now raises BadRequest if the filename is invalid on
    the server OS (pull request 1763).
  • Added the JSONIFY_MIMETYPE configuration variable (pull request 1728).
  • Exceptions during teardown handling will no longer leave bad application
    contexts lingering around.


(bugfix release, release date to be announced)

  • Fixed broken test_appcontext_signals() test case.
  • Raise an :exc:AttributeError in :func:flask.helpers.find_package with a
    useful message explaining why it is raised when a PEP 302 import hook is used
    without an is_package() method.
  • Fixed an issue causing exceptions raised before entering a request or app
    context to be passed to teardown handlers.
  • Fixed an issue with query parameters getting removed from requests in
    the test client when absolute URLs were requested.
  • Made before_first_request into a decorator as intended.
  • Fixed an etags bug when sending a file streams with a name.
  • Fixed send_from_directory not expanding to the application root path
  • Changed logic of before first request handlers to flip the flag after
    invoking. This will allow some uses that are potentially dangerous but
    should probably be permitted.
  • Fixed Python 3 bug when a handler from app.url_build_error_handlers
    reraises the BuildError.

    development server.


Released on December 31st 2017

  • HTTP exceptions are now automatically caught by
  • Added support for edge as browser.
  • Added support for platforms that lack SpooledTemporaryFile.
  • Add support for etag handling through if-match
  • Added support for the SameSite cookie attribute.
  • Added werkzeug.wsgi.ProxyMiddleware
  • Implemented has for NullCache
  • get_multi on cache clients now returns lists all the time.
  • Improved the watchdog observer shutdown for the reloader to not crash
    on exit on older Python versions.
  • Added support for filename* filename attributes according to
    RFC 2231
  • Resolved an issue where machine ID for the reloader PIN was not
    read accurately on windows.
  • Added a workaround for syntax errors in init files in the reloader.
  • Added support for using the reloader with console scripts on windows.
  • The built-in HTTP server will no longer close a connection in cases
    where no HTTP body is expected (204, 204, HEAD requests etc.)
  • The EnvironHeaders object now skips over empty content type and
    lengths if they are set to falsy values.
  • Werkzeug will no longer send the content-length header on 1xx or
    204/304 responses.
  • Cookie values are now also permitted to include slashes and equal
    signs without quoting.
  • Relaxed the regex for the routing converter arguments.
  • If cookies are sent without values they are now assumed to have an
    empty value and the parser accepts this. Previously this could have
    corrupted cookies that followed the value.
  • The test Client and EnvironBuilder now support mimetypes like
    the request object does.
  • Added support for static weights in URL rules.
  • Better handle some more complex reloader scenarios where sys.path
    contained non directory paths.
  • EnvironHeaders no longer raises weird errors if non string keys
    are passed to it.


Released on December 7th 2017

  • Deprecate support for Python 2.6 and 3.3. CI tests will not run
    for these versions, and support will be dropped completely in the next
    version. (pallets/meta24_)
  • Raise TypeError when port is not an integer. (1088_)
  • Fully deprecate werkzeug.script. Use Click_ instead. (1090_)
  • response.age is parsed as a timedelta. Previously, it was
    incorrectly treated as a datetime. The header value is an integer
    number of seconds, not a date string. (414_)
  • Fix a bug in TypeConversionDict where errors are not propagated
    when using the converter. (1102_)
  • Authorization.qop is a string instead of a set, to comply with
    RFC 2617. (984_)
  • An exception is raised when an encoded cookie is larger than, by
    default, 4093 bytes. Browsers may silently ignore cookies larger than
    this. BaseResponse has a new attribute max_cookie_size and
    dump_cookie has a new argument max_size to configure this.
    (780, 1109)
  • Fix a TypeError in werkzeug.contrib.lint.GuardedIterator.close.
  • BaseResponse.calculate_content_length now correctly works for
    Unicode responses on Python 3. It first encodes using
    iter_encoded. (705_)
  • Secure cookie contrib works with string secret key on Python 3.
  • Shared data middleware accepts a list instead of a dict of static
    locations to preserve lookup order. (1197_)
  • HTTP header values without encoding can contain single quotes.
  • The built-in dev server supports receiving requests with chunked
    transfer encoding. (1198_)

  • BuildErrors are now more informative. They come with a complete sentence
    as error message, and also provide suggestions (pull request 691).
  • Fix a bug in the user agent parser where Safari's build number instead of
    version would be extracted (pull request 703).
  • Fixed issue where RedisCache set_many was broken for twemproxy, which doesn't
    support the default MULTI command (pull request 702).
  • mimetype parameters on request and response classes are now always
    converted to lowercase.
  • Changed cache so that cache never expires if timeout is 0. This also fixes
    an issue with redis setex (issue 550)
  • Werkzeug now assumes UTF-8 as filesystem encoding on Unix if Python
    detected it as ASCII.
  • New optional has method on caches.
  • Fixed various bugs in parse_options_header (pull request 643).
  • If the reloader is enabled the server will now open the socket in the parent
    process if this is possible. This means that when the reloader kicks in
    the connection from client will wait instead of tearing down. This does
    not work on all Python versions.
  • Implemented PIN based authentication for the debugger. This can optionally
    be disabled but is discouraged. This change was necessary as it has been
    discovered that too many people run the debugger in production.
  • Devserver no longer requires SSL module to be installed.


(bugfix release, release date yet to be decided)

  • Reloader: Correctly detect file changes made by moving temporary files over
    the original, which is e.g. the case with PyCharm (pull request 722).
  • Fix bool behavior of werkzeug.datastructures.ETags under Python 3 (issue
