(`2748`_)\n-   Fix error with ``flask routes`` command when there are no routes.\n    (`2751`_)\n\n.. _2748: https://github.com/pallets/flask/pull/2748\n.. _2751: https://github.com/pallets/flask/issues/2751\n   ```\n   \n  \n  \n   ### 1.0.1\n   ```\n   -------------\n\nReleased on April 29th 2018\n\n-   Fix registering partials (with no ``__name__``) as view functions.\n    (`2730`_)\n-   Don&#39;t treat lists returned from view functions the same as tuples.\n    Only tuples are interpreted as response data. (`2736`_)\n-   Extra slashes between a blueprint&#39;s ``url_prefix`` and a route URL\n    are merged. This fixes some backwards compatibility issues with the\n    change in 1.0. (`2731`_, `2742`_)\n-   Only trap ``BadRequestKeyError`` errors in debug mode, not all\n    ``BadRequest`` errors. This allows ``abort(400)`` to continue\n    working as expected. (`2735`_)\n-   The ``FLASK_SKIP_DOTENV`` environment variable can be set to ``1``\n    to skip automatically loading dotenv files. (`2722`_)\n\n.. _2722: https://github.com/pallets/flask/issues/2722\n.. _2730: https://github.com/pallets/flask/pull/2730\n.. _2731: https://github.com/pallets/flask/issues/2731\n.. _2735: https://github.com/pallets/flask/issues/2735\n.. _2736: https://github.com/pallets/flask/issues/2736\n.. _2742: https://github.com/pallets/flask/issues/2742\n   ```\n   \n  \n  \n   ### 1.0\n   ```\n   -----------\n\nReleased on April 26th 2018\n\n-   **Python 2.6 and 3.3 are no longer supported.** (`pallets/meta24`_)\n-   Bump minimum dependency versions to the latest stable versions:\n    Werkzeug &gt;= 0.14, Jinja &gt;= 2.10, itsdangerous &gt;= 0.24, Click &gt;= 5.1.\n    (`2586`_)\n-   Skip :meth:`app.run &lt;Flask.run&gt;` when a Flask application is run\n    from the command line. This avoids some behavior that was confusing\n    to debug.\n-   Change the default for :data:`JSONIFY_PRETTYPRINT_REGULAR` to\n    ``False``. :func:`~json.jsonify` returns a compact format by\n    default, and an indented format in debug mode. (`2193`_)\n-   :meth:`Flask.__init__ &lt;Flask&gt;` accepts the ``host_matching``\n    argument and sets it on :attr:`~Flask.url_map`. (`1559`_)\n-   :meth:`Flask.__init__ &lt;Flask&gt;` accepts the ``static_host`` argument\n    and passes it as the ``host`` argument when defining the static\n    route. (`1559`_)\n-   :func:`send_file` supports Unicode in ``attachment_filename``.\n    (`2223`_)\n-   Pass ``_scheme`` argument from :func:`url_for` to\n    :meth:`~Flask.handle_url_build_error`. (`2017`_)\n-   :meth:`~Flask.add_url_rule` accepts the\n    ``provide_automatic_options`` argument to disable adding the\n    ``OPTIONS`` method. (`1489`_)\n-   :class:`~views.MethodView` subclasses inherit method handlers from\n    base classes. (`1936`_)\n-   Errors caused while opening the session at the beginning of the\n    request are handled by the app&#39;s error handlers. (`2254`_)\n-   Blueprints gained :attr:`~Blueprint.json_encoder` and\n    :attr:`~Blueprint.json_decoder` attributes to override the app&#39;s\n    encoder and decoder. (`1898`_)\n-   :meth:`Flask.make_response` raises ``TypeError`` instead of\n    ``ValueError`` for bad response types. The error messages have been\n    improved to describe why the type is invalid. (`2256`_)\n-   Add ``routes`` CLI command to output routes registered on the\n    application. (`2259`_)\n-   Show warning when session cookie domain is a bare hostname or an IP\n    address, as these may not behave properly in some browsers, such as\n    Chrome. (`2282`_)\n-   Allow IP address as exact session cookie domain. (`2282`_)\n-   ``SESSION_COOKIE_DOMAIN`` is set if it is detected through\n    ``SERVER_NAME``. (`2282`_)\n-   Auto-detect zero-argument app factory called ``create_app`` or\n    ``make_app`` from ``FLASK_APP``. (`2297`_)\n-   Factory functions are not required to take a ``script_info``\n    parameter to work with the ``flask`` command. If they take a single\n    parameter or a parameter named ``script_info``, the\n    :class:`~cli.ScriptInfo` object will be passed. (`2319`_)\n-   ``FLASK_APP`` can be set to an app factory, with arguments if\n    needed, for example ``FLASK_APP=myproject.app:create_app(&#39;dev&#39;)``.\n    (`2326`_)\n-   ``FLASK_APP`` can point to local packages that are not installed in\n    editable mode, although ``pip install -e`` is still preferred.\n    (`2414`_)\n-   The :class:`~views.View` class attribute\n    :attr:`~views.View.provide_automatic_options` is set in\n    :meth:`~views.View.as_view`, to be detected by\n    :meth:`~Flask.add_url_rule`. (`2316`_)\n-   Error handling will try handlers registered for ``blueprint, code``,\n    ``app, code``, ``blueprint, exception``, ``app, exception``.\n    (`2314`_)\n-   ``Cookie`` is added to the response&#39;s ``Vary`` header if the session\n    is accessed at all during the request (and not deleted). (`2288`_)\n-   :meth:`~Flask.test_request_context` accepts ``subdomain`` and\n    ``url_scheme`` arguments for use when building the base URL.\n    (`1621`_)\n-   Set :data:`APPLICATION_ROOT` to ``&#39;/&#39;`` by default. This was already\n    the implicit default when it was set to ``None``.\n-   :data:`TRAP_BAD_REQUEST_ERRORS` is enabled by default in debug mode.\n    ``BadRequestKeyError`` has a message with the bad key in debug mode\n    instead of the generic bad request message. (`2348`_)\n-   Allow registering new tags with\n    :class:`~json.tag.TaggedJSONSerializer` to support storing other\n    types in the session cookie. (`2352`_)\n-   Only open the session if the request has not been pushed onto the\n    context stack yet. This allows :func:`~stream_with_context`\n    generators to access the same session that the containing view uses.\n    (`2354`_)\n-   Add ``json`` keyword argument for the test client request methods.\n    This will dump the given object as JSON and set the appropriate\n    content type. (`2358`_)\n-   Extract JSON handling to a mixin applied to both the\n    :class:`Request` and :class:`Response` classes. This adds the\n    :meth:`~Response.is_json` and :meth:`~Response.get_json` methods to\n    the response to make testing JSON response much easier. (`2358`_)\n-   Removed error handler caching because it caused unexpected results\n    for some exception inheritance hierarchies. Register handlers\n    explicitly for each exception if you want to avoid traversing the\n    MRO. (`2362`_)\n-   Fix incorrect JSON encoding of aware, non-UTC datetimes. (`2374`_)\n-   Template auto reloading will honor debug mode even even if\n    :attr:`~Flask.jinja_env` was already accessed. (`2373`_)\n-   The following old deprecated code was removed. (`2385`_)\n\n    -   ``flask.ext`` - import extensions directly by their name instead\n        of through the ``flask.ext`` namespace. For example,\n        ``import flask.ext.sqlalchemy`` becomes\n        ``import flask_sqlalchemy``.\n    -   ``Flask.init_jinja_globals`` - extend\n        :meth:`Flask.create_jinja_environment` instead.\n    -   ``Flask.error_handlers`` - tracked by\n        :attr:`Flask.error_handler_spec`, use :meth:`Flask.errorhandler`\n        to register handlers.\n    -   ``Flask.request_globals_class`` - use\n        :attr:`Flask.app_ctx_globals_class` instead.\n    -   ``Flask.static_path`` - use :attr:`Flask.static_url_path`\n        instead.\n    -   ``Request.module`` - use :attr:`Request.blueprint` instead.\n\n-   The :attr:`Request.json` property is no longer deprecated.\n    (`1421`_)\n-   Support passing a :class:`~werkzeug.test.EnvironBuilder` or\n    ``dict`` to :meth:`test_client.open &lt;werkzeug.test.Client.open&gt;`.\n    (`2412`_)\n-   The ``flask`` command and :meth:`Flask.run` will load environment\n    variables from ``.env`` and ``.flaskenv`` files if python-dotenv is\n    installed. (`2416`_)\n-   When passing a full URL to the test client, the scheme in the URL is\n    used instead of :data:`PREFERRED_URL_SCHEME`. (`2430`_)\n-   :attr:`Flask.logger` has been simplified. ``LOGGER_NAME`` and\n    ``LOGGER_HANDLER_POLICY`` config was removed. The logger is always\n    named ``flask.app``. The level is only set on first access, it\n    doesn&#39;t check :attr:`Flask.debug` each time. Only one format is\n    used, not different ones depending on :attr:`Flask.debug`. No\n    handlers are removed, and a handler is only added if no handlers are\n    already configured. (`2436`_)\n-   Blueprint view function names may not contain dots. (`2450`_)\n-   Fix a ``ValueError`` caused by invalid ``Range`` requests in some\n    cases. (`2526`_)\n-   The development server uses threads by default. (`2529`_)\n-   Loading config files with ``silent=True`` will ignore\n    :data:`~errno.ENOTDIR` errors. (`2581`_)\n-   Pass ``--cert`` and ``--key`` options to ``flask run`` to run the\n    development server over HTTPS. (`2606`_)\n-   Added :data:`SESSION_COOKIE_SAMESITE` to control the ``SameSite``\n    attribute on the session cookie. (`2607`_)\n-   Added :meth:`~flask.Flask.test_cli_runner` to create a Click runner\n    that can invoke Flask CLI commands for testing. (`2636`_)\n-   Subdomain matching is disabled by default and setting\n    :data:`SERVER_NAME` does not implicily enable it. It can be enabled\n    by passing ``subdomain_matching=True`` to the ``Flask`` constructor.\n    (`2635`_)\n-   A single trailing slash is stripped from the blueprint\n    ``url_prefix`` when it is registered with the app. (`2629`_)\n-   :meth:`Request.get_json` doesn&#39;t cache the\n    result if parsing fails when ``silent`` is true. (`2651`_)\n-   :func:`Request.get_json` no longer accepts arbitrary encodings.\n    Incoming JSON should be encoded using UTF-8 per :rfc:`8259`, but\n    Flask will autodetect UTF-8, -16, or -32. (`2691`_)\n-   Added :data:`MAX_COOKIE_SIZE` and :attr:`Response.max_cookie_size`\n    to control when Werkzeug warns about large cookies that browsers may\n    ignore. (`2693`_)\n-   Updated documentation theme to make docs look better in small\n    windows. (`2709`_)\n-   Rewrote the tutorial docs and example project to take a more\n    structured approach to help new users avoid common pitfalls.\n    (`2676`_)\n\n.. _pallets/meta24: https://github.com/pallets/meta/issues/24\n.. _1421: https://github.com/pallets/flask/issues/1421\n.. _1489: https://github.com/pallets/flask/pull/1489\n.. _1559: https://github.com/pallets/flask/issues/1559\n.. _1621: https://github.com/pallets/flask/pull/1621\n.. _1898: https://github.com/pallets/flask/pull/1898\n.. _1936: https://github.com/pallets/flask/pull/1936\n.. _2017: https://github.com/pallets/flask/pull/2017\n.. _2193: https://github.com/pallets/flask/pull/2193\n.. _2223: https://github.com/pallets/flask/pull/2223\n.. _2254: https://github.com/pallets/flask/pull/2254\n.. _2256: https://github.com/pallets/flask/pull/2256\n.. _2259: https://github.com/pallets/flask/pull/2259\n.. _2282: https://github.com/pallets/flask/pull/2282\n.. _2288: https://github.com/pallets/flask/pull/2288\n.. _2297: https://github.com/pallets/flask/pull/2297\n.. _2314: https://github.com/pallets/flask/pull/2314\n.. _2316: https://github.com/pallets/flask/pull/2316\n.. _2319: https://github.com/pallets/flask/pull/2319\n.. _2326: https://github.com/pallets/flask/pull/2326\n.. _2348: https://github.com/pallets/flask/pull/2348\n.. _2352: https://github.com/pallets/flask/pull/2352\n.. _2354: https://github.com/pallets/flask/pull/2354\n.. _2358: https://github.com/pallets/flask/pull/2358\n.. _2362: https://github.com/pallets/flask/pull/2362\n.. _2374: https://github.com/pallets/flask/pull/2374\n.. _2373: https://github.com/pallets/flask/pull/2373\n.. _2385: https://github.com/pallets/flask/issues/2385\n.. _2412: https://github.com/pallets/flask/pull/2412\n.. _2414: https://github.com/pallets/flask/pull/2414\n.. _2416: https://github.com/pallets/flask/pull/2416\n.. _2430: https://github.com/pallets/flask/pull/2430\n.. _2436: https://github.com/pallets/flask/pull/2436\n.. _2450: https://github.com/pallets/flask/pull/2450\n.. _2526: https://github.com/pallets/flask/issues/2526\n.. _2529: https://github.com/pallets/flask/pull/2529\n.. _2586: https://github.com/pallets/flask/issues/2586\n.. _2581: https://github.com/pallets/flask/pull/2581\n.. _2606: https://github.com/pallets/flask/pull/2606\n.. _2607: https://github.com/pallets/flask/pull/2607\n.. _2636: https://github.com/pallets/flask/pull/2636\n.. _2635: https://github.com/pallets/flask/pull/2635\n.. _2629: https://github.com/pallets/flask/pull/2629\n.. _2651: https://github.com/pallets/flask/issues/2651\n.. _2676: https://github.com/pallets/flask/pull/2676\n.. _2691: https://github.com/pallets/flask/pull/2691\n.. _2693: https://github.com/pallets/flask/pull/2693\n.. _2709: https://github.com/pallets/flask/pull/2709\n   ```\n   \n  \n  \n   ### 0.12.4\n   ```\n   --------------\n\nReleased on April 29 2018\n\n-   Repackage 0.12.3 to fix package layout issue.

This improves thread-safety.\n   ```\n   \n  \n  \n   ### 2.16.5\n   ```\n   -------------------\n\n-   Improvements to `$ python -m requests.help`.\n   ```\n   \n  \n  \n   ### 2.16.4\n   ```\n   -------------------\n\n-   Introduction of the `$ python -m requests.help` command, for\n    debugging with maintainers!\n   ```\n   \n  \n  \n   ### 2.16.3\n   ```\n   -------------------\n\n-   Further restored the `requests.packages` namespace for compatibility\n    reasons.\n   ```\n   \n  \n  \n   ### 2.16.2\n   ```\n   -------------------\n\n-   Further restored the `requests.packages` namespace for compatibility\n    reasons.\n\nNo code modification (noted below) should be necessary any longer.\n   ```\n   \n  \n  \n   ### 2.16.1\n   ```\n   -------------------\n\n-   Restored the `requests.packages` namespace for compatibility\n    reasons.\n-   Bugfix for `urllib3` version parsing.\n\n**Note**: code that was written to import against the\n`requests.packages` namespace previously will have to import code that\nrests at this module-level now.\n\nFor example:\n\n    from requests.packages.urllib3.poolmanager import PoolManager\n\nWill need to be re-written to be:\n\n    from requests.packages import urllib3\n    urllib3.poolmanager.PoolManager\n\nOr, even better:\n\n    from urllib3.poolmanager import PoolManager\n   ```\n   \n  \n  \n   ### 2.16.0\n   ```\n   -------------------\n\n-   Unvendor ALL the things!\n   ```\n   \n  \n  \n   ### 2.15.1\n   ```\n   -------------------\n\n-   Everyone makes mistakes.\n   ```\n   \n  \n  \n   ### 2.15.0\n   ```\n   -------------------\n\n**Improvements**\n\n-   Introduction of the `Response.next` property, for getting the next\n    `PreparedResponse` from a redirect chain (when\n    `allow_redirects=False`).\n-   Internal refactoring of `__version__` module.\n\n**Bugfixes**\n\n-   Restored once-optional parameter for\n    `requests.utils.get_environ_proxies()`.\n   ```\n   \n  \n  \n   ### 2.14.2\n   ```\n   -------------------\n\n**Bugfixes**\n\n-   Changed a less-than to an equal-to and an or in the dependency\n    markers to widen compatibility with older setuptools releases.\n   ```\n   \n  \n  \n   ### 2.14.1\n   ```\n   -------------------\n\n**Bugfixes**\n\n-   Changed the dependency markers to widen compatibility with older pip\n    releases.\n   ```\n   \n  \n  \n   ### 2.14.0\n   ```\n   -------------------\n\n**Improvements**\n\n-   It is now possible to pass `no_proxy` as a key to the `proxies`\n    dictionary to provide handling similar to the `NO_PROXY` environment\n    variable.\n-   When users provide invalid paths to certificate bundle files or\n    directories Requests now raises `IOError`, rather than failing at\n    the time of the HTTPS request with a fairly inscrutable certificate\n    validation error.\n-   The behavior of `SessionRedirectMixin` was slightly altered.\n    `resolve_redirects` will now detect a redirect by calling\n    `get_redirect_target(response)` instead of directly querying\n    `Response.is_redirect` and `Response.headers[&#39;location&#39;]`. Advanced\n    users will be able to process malformed redirects more easily.\n-   Changed the internal calculation of elapsed request time to have\n    higher resolution on Windows.\n-   Added `win_inet_pton` as conditional dependency for the `[socks]`\n    extra on Windows with Python 2.7.\n-   Changed the proxy bypass implementation on Windows: the proxy bypass\n    check doesn&#39;t use forward and reverse DNS requests anymore\n-   URLs with schemes that begin with `http` but are not `http` or\n    `https` no longer have their host parts forced to lowercase.\n\n**Bugfixes**\n\n-   Much improved handling of non-ASCII `Location` header values in\n    redirects. Fewer `UnicodeDecodeErrors` are encountered on Python 2,\n    and Python 3 now correctly understands that Latin-1 is unlikely to\n    be the correct encoding.\n-   If an attempt to `seek` file to find out its length fails, we now\n    appropriately handle that by aborting our content-length\n    calculations.\n-   Restricted `HTTPDigestAuth` to only respond to auth challenges made\n    on 4XX responses, rather than to all auth challenges.\n-   Fixed some code that was firing `DeprecationWarning` on Python 3.6.\n-   The dismayed person emoticon (`/o\\\\`) no longer has a big head. I&#39;m\n    sure this is what you were all worrying about most.\n\n**Miscellaneous**\n\n-   Updated bundled urllib3 to v1.21.1.\n-   Updated bundled chardet to v3.0.2.\n-   Updated bundled idna to v2.5.\n-   Updated bundled certifi to 2017.4.17.\n   ```\n   \n  \n  \n   ### 2.13.0\n   ```\n   -------------------\n\n**Features**\n\n-   Only load the `idna` library when we&#39;ve determined we need it. This\n    will save some memory for users.\n\n**Miscellaneous**\n\n-   Updated bundled urllib3 to 1.20.\n-   Updated bundled idna to 2.2.\n   ```\n   \n  \n  \n   ### 2.12.5\n   ```\n   -------------------\n\n**Bugfixes**\n\n-   Fixed an issue with JSON encoding detection, specifically detecting\n    big-endian UTF-32 with BOM.\n   ```\n   \n  \n  \n   ### 2.12.4\n   ```\n   -------------------\n\n**Bugfixes**\n\n-   Fixed regression from 2.12.2 where non-string types were rejected in\n    the basic auth parameters. While support for this behaviour has been\n    readded, the behaviour is deprecated and will be removed in the\n    future.\n   ```\n   \n  \n  \n   ### 2.12.3\n   ```\n   -------------------\n\n**Bugfixes**\n\n-   Fixed regression from v2.12.1 for URLs with schemes that begin with\n    &quot;http&quot;. These URLs have historically been processed as though they\n    were HTTP-schemed URLs, and so have had parameters added. This was\n    removed in v2.12.2 in an overzealous attempt to resolve problems\n    with IDNA-encoding those URLs. This change was reverted: the other\n    fixes for IDNA-encoding have been judged to be sufficient to return\n    to the behaviour Requests had before v2.12.0.\n   ```\n   \n  \n  \n   ### 2.12.2\n   ```\n   -------------------\n\n**Bugfixes**\n\n-   Fixed several issues with IDNA-encoding URLs that are technically\n    invalid but which are widely accepted. Requests will now attempt to\n    IDNA-encode a URL if it can but, if it fails, and the host contains\n    only ASCII characters, it will be passed through optimistically.\n    This will allow users to opt-in to using IDNA2003 themselves if they\n    want to, and will also allow technically invalid but still common\n    hostnames.\n-   Fixed an issue where URLs with leading whitespace would raise\n    `InvalidSchema` errors.\n-   Fixed an issue where some URLs without the HTTP or HTTPS schemes\n    would still have HTTP URL preparation applied to them.\n-   Fixed an issue where Unicode strings could not be used in basic\n    auth.\n-   Fixed an issue encountered by some Requests plugins where\n    constructing a Response object would cause `Response.content` to\n    raise an `AttributeError`.\n   ```\n   \n  \n  \n   ### 2.12.1\n   ```\n   -------------------\n\n**Bugfixes**\n\n-   Updated setuptools &#39;security&#39; extra for the new PyOpenSSL backend in\n    urllib3.\n\n**Miscellaneous**\n\n-   Updated bundled urllib3 to 1.19.1.\n   ```\n   \n  \n  \n   ### 2.12.0\n   ```\n   -------------------\n\n**Improvements**\n\n-   Updated support for internationalized domain names from IDNA2003 to\n    IDNA2008. This updated support is required for several forms of IDNs\n    and is mandatory for .de domains.\n-   Much improved heuristics for guessing content lengths: Requests will\n    no longer read an entire `StringIO` into memory.\n-   Much improved logic for recalculating `Content-Length` headers for\n    `PreparedRequest` objects.\n-   Improved tolerance for file-like objects that have no `tell` method\n    but do have a `seek` method.\n-   Anything that is a subclass of `Mapping` is now treated like a\n    dictionary by the `data=` keyword argument.\n-   Requests now tolerates empty passwords in proxy credentials, rather\n    than stripping the credentials.\n-   If a request is made with a file-like object as the body and that\n    request is redirected with a 307 or 308 status code, Requests will\n    now attempt to rewind the body object so it can be replayed.\n\n**Bugfixes**\n\n-   When calling `response.close`, the call to `close` will be\n    propagated through to non-urllib3 backends.\n-   Fixed issue where the `ALL_PROXY` environment variable would be\n    preferred over scheme-specific variables like `HTTP_PROXY`.\n-   Fixed issue where non-UTF8 reason phrases got severely mangled by\n    falling back to decoding using ISO 8859-1 instead.\n-   Fixed a bug where Requests would not correctly correlate cookies set\n    when using custom Host headers if those Host headers did not use the\n    native string type for the platform.\n\n**Miscellaneous**\n\n-   Updated bundled urllib3 to 1.19.\n-   Updated bundled certifi certs to 2016.09.26.\n   ```\n   \n  \n</details>\n\n\n \n\n<details>\n  <summary>Links</summary>\n  \n  - PyPI: https://pypi.org/project/requests\n  - Changelog: https://pyup.io/changelogs/requests/\n  - Homepage: http://python-requests.org\n</details>\n\n\n\n\n\n### Update [cryptography](https://pypi.org/project/cryptography) from **2.0.2** to **2.4.1**.\n\n\n<details>\n  <summary>Changelog</summary>\n  \n  \n   ### 2.4.1\n   ```\n   ~~~~~~~~~~~~~~~~~~\n\n* Fixed a build breakage in our ``manylinux1`` wheels.\n\n.. _v2-4:\n   ```\n   \n  \n  \n   ### 2.4\n   ```\n   ~~~~~~~~~~~~~~~~\n\n* **BACKWARDS INCOMPATIBLE:** Dropped support for LibreSSL 2.4.x.\n* Deprecated OpenSSL 1.0.1 support. OpenSSL 1.0.1 is no longer supported by\n  the OpenSSL project. At this time there is no time table for dropping\n  support, however we strongly encourage all users to upgrade or install\n  ``cryptography`` from a wheel.\n* Added initial :doc:`OCSP &lt;/x509/ocsp&gt;` support.\n* Added support for :class:`~cryptography.x509.PrecertPoison`.\n\n.. _v2-3-1:\n   ```\n   \n  \n  \n   ### 2.3.1\n   ```\n   ~~~~~~~~~~~~~~~~~~\n\n* Updated Windows, macOS, and ``manylinux1`` wheels to be compiled with\n  OpenSSL 1.1.0i.\n\n.. _v2-3:\n   ```\n   \n  \n  \n   ### 2.3\n   ```\n   ~~~~~~~~~~~~~~~~\n\n* **SECURITY ISSUE:**\n  :meth:`~cryptography.hazmat.primitives.ciphers.AEADDecryptionContext.finalize_with_tag`\n  allowed tag truncation by default which can allow tag forgery in some cases.\n  The method now enforces the ``min_tag_length`` provided to the\n  :class:`~cryptography.hazmat.primitives.ciphers.modes.GCM` constructor.\n  *CVE-2018-10903*\n* Added support for Python 3.7.\n* Added :meth:`~cryptography.fernet.Fernet.extract_timestamp` to get the\n  authenticated timestamp of a :doc:`Fernet &lt;/fernet&gt;` token.\n* Support for Python 2.7.x without ``hmac.compare_digest`` has been deprecated.\n  We will require Python 2.7.7 or higher (or 2.7.6 on Ubuntu) in the next\n  ``cryptography`` release.\n* Fixed multiple issues preventing ``cryptography`` from compiling against\n  LibreSSL 2.7.x.\n* Added\n  :class:`~cryptography.x509.CertificateRevocationList.get_revoked_certificate_by_serial_number`\n  for quick serial number searches in CRLs.\n* The :class:`~cryptography.x509.RelativeDistinguishedName` class now\n  preserves the order of attributes. Duplicate attributes now raise an error\n  instead of silently discarding duplicates.\n* :func:`~cryptography.hazmat.primitives.keywrap.aes_key_unwrap` and\n  :func:`~cryptography.hazmat.primitives.keywrap.aes_key_unwrap_with_padding`\n  now raise :class:`~cryptography.hazmat.primitives.keywrap.InvalidUnwrap` if\n  the wrapped key is an invalid length, instead of ``ValueError``.\n\n.. _v2-2-2:\n   ```\n   \n  \n  \n   ### 2.2.2\n   ```\n   ~~~~~~~~~~~~~~~~~~\n\n* Updated Windows, macOS, and ``manylinux1`` wheels to be compiled with\n  OpenSSL 1.1.0h.\n\n.. _v2-2-1:\n   ```\n   \n  \n  \n   ### 2.2.1\n   ```\n   ~~~~~~~~~~~~~~~~~~\n\n* Reverted a change to ``GeneralNames`` which prohibited having zero elements,\n  due to breakages.\n* Fixed a bug in\n  :func:`~cryptography.hazmat.primitives.keywrap.aes_key_unwrap_with_padding`\n  that caused it to raise ``InvalidUnwrap`` when key length modulo 8 was\n  zero.\n\n\n.. _v2-2:\n   ```\n   \n  \n  \n   ### 2.2\n   ```\n   ~~~~~~~~~~~~~~~~\n\n* **BACKWARDS INCOMPATIBLE:** Support for Python 2.6 has been dropped.\n* Resolved a bug in ``HKDF`` that incorrectly constrained output size.\n* Added :class:`~cryptography.hazmat.primitives.asymmetric.ec.BrainpoolP256R1`,\n  :class:`~cryptography.hazmat.primitives.asymmetric.ec.BrainpoolP384R1`, and\n  :class:`~cryptography.hazmat.primitives.asymmetric.ec.BrainpoolP512R1` to\n  support inter-operating with systems like German smart meters.\n* Added token rotation support to :doc:`Fernet &lt;/fernet&gt;` with\n  :meth:`~cryptography.fernet.MultiFernet.rotate`.\n* Fixed a memory leak in\n  :func:`~cryptography.hazmat.primitives.asymmetric.ec.derive_private_key`.\n* Added support for AES key wrapping with padding via\n  :func:`~cryptography.hazmat.primitives.keywrap.aes_key_wrap_with_padding`\n  and\n  :func:`~cryptography.hazmat.primitives.keywrap.aes_key_unwrap_with_padding`\n  .\n* Allow loading DSA keys with 224 bit ``q``.\n\n.. _v2-1-4:\n   ```\n   \n  \n  \n   ### 2.1.4\n   ```\n   ~~~~~~~~~~~~~~~~~~\n\n* Added ``X509_up_ref`` for an upcoming ``pyOpenSSL`` release.\n\n.. _v2-1-3:\n   ```\n   \n  \n  \n   ### 2.1.3\n   ```\n   ~~~~~~~~~~~~~~~~~~\n\n* Updated Windows, macOS, and ``manylinux1`` wheels to be compiled with\n  OpenSSL 1.1.0g.\n\n.. _v2-1-2:\n   ```\n   \n  \n  \n   ### 2.1.2\n   ```\n   ~~~~~~~~~~~~~~~~~~\n\n* Corrected a bug with the ``manylinux1`` wheels where OpenSSL&#39;s stack was\n  marked executable.\n\n.. _v2-1-1:\n   ```\n   \n  \n  \n   ### 2.1.1\n   ```\n   ~~~~~~~~~~~~~~~~~~\n\n* Fixed support for install with the system ``pip`` on Ubuntu 16.04.\n\n.. _v2-1:\n   ```\n   \n  \n  \n   ### 2.1\n   ```\n   ~~~~~~~~~~~~~~~~\n\n* **FINAL DEPRECATION** Python 2.6 support is deprecated, and will be removed\n  in the next release of ``cryptography``.\n* **BACKWARDS INCOMPATIBLE:** ``Whirlpool``, ``RIPEMD160``, and\n  ``UnsupportedExtension`` have been removed in accordance with our\n  :doc:`/api-stability` policy.\n* **BACKWARDS INCOMPATIBLE:**\n  :attr:`DNSName.value &lt;cryptography.x509.DNSName.value&gt;`,\n  :attr:`RFC822Name.value &lt;cryptography.x509.RFC822Name.value&gt;`, and\n  :attr:`UniformResourceIdentifier.value\n  &lt;cryptography.x509.UniformResourceIdentifier.value&gt;`\n  will now return an :term:`A-label` string when parsing a certificate\n  containing an internationalized domain name (IDN) or if the caller passed\n  a :term:`U-label` to the constructor. See below for additional deprecations\n  related to this change.\n* Installing ``cryptography`` now requires ``pip`` 6 or newer.\n* Deprecated passing :term:`U-label` strings to the\n  :class:`~cryptography.x509.DNSName`,\n  :class:`~cryptography.x509.UniformResourceIdentifier`, and\n  :class:`~cryptography.x509.RFC822Name` constructors. Instead, users should\n  pass values as :term:`A-label` strings with ``idna`` encoding if necessary.\n  This change will not affect anyone who is not processing internationalized\n  domains.\n* Added support for\n  :class:`~cryptography.hazmat.primitives.ciphers.algorithms.ChaCha20`. In\n  most cases users should choose\n  :class:`~cryptography.hazmat.primitives.ciphers.aead.ChaCha20Poly1305`\n  rather than using this unauthenticated form.\n* Added :meth:`~cryptography.x509.CertificateRevocationList.is_signature_valid`\n  to :class:`~cryptography.x509.CertificateRevocationList`.\n* Support :class:`~cryptography.hazmat.primitives.hashes.BLAKE2b` and\n  :class:`~cryptography.hazmat.primitives.hashes.BLAKE2s` with\n  :class:`~cryptography.hazmat.primitives.hmac.HMAC`.\n* Added support for\n  :class:`~cryptography.hazmat.primitives.ciphers.modes.XTS` mode for\n  AES.\n* Added support for using labels with\n  :class:`~cryptography.hazmat.primitives.asymmetric.padding.OAEP` when using\n  OpenSSL 1.0.2 or greater.\n* Improved compatibility with NSS when issuing certificates from an issuer\n  that has a subject with non-``UTF8String`` string types.\n* Add support for the :class:`~cryptography.x509.DeltaCRLIndicator` extension.\n* Add support for the :class:`~cryptography.x509.TLSFeature`\n  extension. This is commonly used for enabling ``OCSP Must-Staple`` in\n  certificates.\n* Add support for the :class:`~cryptography.x509.FreshestCRL` extension.\n\n.. _v2-0-3:\n   ```\n   \n  \n  \n   ### 2.0.3\n   ```\n   ~~~~~~~~~~~~~~~~~~\n\n* Fixed an issue with weak linking symbols when compiling on macOS\n  versions older than 10.12.\n\n\n.. _v2-0-2:\n   ```\n   \n  \n</details>\n\n\n
