+==========
+Change Log
+==========
+
+This document records all notable changes to `HTTPie <https://httpie.org>`_.
+This project adheres to `Semantic Versioning <https://semver.org/>`_.
+
+
+`2.1.0`_ (2020-04-18)
+---------------------
+
+* Added ``--path-as-is`` to bypass dot segment (``/../`` or ``/./``)
+  URL squashing (#895).
+* Changed the default value ``Accept`` header value for JSON requests from
+  ``application/json, */*`` to ``application/json, */*;q=0.5``
+  to clearly indicate preference (#488).
+* Fixed ``--form`` file upload mixed with redirected ``stdin`` error handling
+  (#840).
+
+
+`2.0.0`_ (2020-01-12)
+-------------------------
+* Removed Python 2.7 support (`EOL Jan 2020 <https://www.python.org/doc/sunset-python-2/>`_).
+* Added ``--offline`` to allow building an HTTP request and printing it but not
+  actually sending it over the network.
+* Replaced the old collect-all-then-process handling of HTTP communication
+  with one-by-one processing of each HTTP request or response as they become
+  available. This means that you can see headers immediately,
+  see what is being sent even if the request fails, etc.
+* Removed automatic config file creation to avoid concurrency issues.
+* Removed the default 30-second connection ``--timeout`` limit.
+* Removed Python’s default limit of 100 response headers.
+* Added ``--max-headers`` to allow setting the max header limit.
+* Added ``--compress`` to allow request body compression.
+* Added ``--ignore-netrc`` to allow bypassing credentials from ``.netrc``.
+* Added ``https`` alias command with ``https://`` as the default scheme.
+* Added ``$ALL_PROXY`` documentation.
+* Added type annotations throughout the codebase.
+* Added ``tests/`` to the PyPi package for the convenience of
+  downstream package maintainers.
+* Fixed an error when ``stdin`` was a closed fd.
+* Improved ``--debug`` output formatting.
+
+
+`1.0.3`_ (2019-08-26)
+---------------------
+
+* Fixed CVE-2019-10751 — the way the output filename is generated for
+  ``--download`` requests without ``--output`` resulting in a redirect has
+  been changed to only consider the initial URL as the base for the generated
+  filename, and not the final one. This fixes a potential security issue under
+  the following scenario:
+
+  1. A ``--download`` request with no explicit ``--output`` is made (e.g.,
+     ``$ http -d example.org/file.txt``), instructing httpie to
+     `generate the output filename <https://httpie.org/doc#downloaded-filename>`_
+     from the ``Content-Disposition`` response header, or from the URL if the header
+     is not provided.
+  2. The server handling the request has been modified by an attacker and
+     instead of the expected response the URL returns a redirect to another
+     URL, e.g., ``attacker.example.org/.bash_profile``, whose response does
+     not provide  a ``Content-Disposition`` header (i.e., the base for the
+     generated filename becomes ``.bash_profile`` instead of ``file.txt``).
+  3. Your current directory doesn’t already contain ``.bash_profile``
+     (i.e., no unique suffix is added to the generated filename).
+  4. You don’t notice the potentially unexpected output filename
+     as reported by httpie in the console output
+     (e.g., ``Downloading 100.00 B to ".bash_profile"``).
+
+  Reported by Raul Onitza and Giulio Comi.
+
+
+`1.0.2`_ (2018-11-14)
+-------------------------
+
+* Fixed tests for installation with pyOpenSSL.
+
+
+`1.0.1`_ (2018-11-14)
+-------------------------
+
+* Removed external URL calls from tests.
+
+
+`1.0.0`_ (2018-11-02)
+-------------------------
+
+* Added ``--style=auto`` which follows the terminal ANSI color styles.
+* Added support for selecting TLS 1.3 via ``--ssl=tls1.3``
+  (available once implemented in upstream libraries).
+* Added ``true``/``false`` as valid values for ``--verify``
+  (in addition to ``yes``/``no``) and the boolean value is case-insensitive.
+* Changed the default ``--style`` from ``solarized`` to ``auto`` (on Windows it stays ``fruity``).
+* Fixed default headers being incorrectly case-sensitive.
+* Removed Python 2.6 support.
+
+
+

+
+
+`0.9.6`_ (2016-08-13)
+---------------------

+* Added Python 3 as a dependency for Homebrew installations
+  to ensure some of the newer HTTP features work out of the box
+  for macOS users (starting with HTTPie 0.9.4.).
+* Added the ability to unset a request header with ``Header:``, and send an
+  empty value with ``Header;``.
+* Added ``--default-scheme <URL_SCHEME>`` to enable things like
+  ``$ alias https='http --default-scheme=https``.
+* Added ``-I`` as a shortcut for ``--ignore-stdin``.
+* Added fish shell completion (located in ``extras/httpie-completion.fish``
+  in the Github repo).
+* Updated ``requests`` to 2.10.0 so that SOCKS support can be added via
+  ``pip install requests[socks]``.
+* Changed the default JSON ``Accept`` header from ``application/json``
+  to ``application/json, */*``.
+* Changed the pre-processing of request HTTP headers so that any leading
+  and trailing whitespace is removed.
+
+
+`0.9.4`_ (2016-07-01)
+---------------------
+
+* Added ``Content-Type`` of files uploaded in ``multipart/form-data`` requests
+* Added ``--ssl=<PROTOCOL>`` to specify the desired SSL/TLS protocol version
+  to use for HTTPS requests.
+* Added JSON detection with ``--json, -j`` to work around incorrect
+  ``Content-Type``

+* Added ``-A`` as short name for ``--auth-type``
+* Added ``-F`` as short name for ``--follow``
+* Removed the ``implicit_content_type`` config option
+  (use ``"default_options": ["--form"]`` instead)
+* Redirected ``stdout`` doesn't trigger an error anymore when ``--output FILE``
+  is set
+* Changed the default ``--style`` back to ``solarized`` for better support
+  of light and dark terminals
+* Improved ``--debug`` output
+* Fixed ``--session`` when used with ``--download``
+* Fixed ``--download`` to trim too long filenames before saving the file
+* Fixed the handling of ``Content-Type`` with multiple ``+subtype`` parts
+* Removed the XML formatter as the implementation suffered from multiple issues
+
+
+
+`0.9.3`_ (2016-01-01)
+---------------------
+
+* Changed the default color ``--style`` from ``solarized`` to ``monokai``
+* Added basic Bash autocomplete support (need to be installed manually)

+* Added support for Requests transport adapter plugins
+  (see `httpie-unixsocket <https://github.com/httpie/httpie-unixsocket>`_

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at jakub@roztocil.co. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is

+######################
+Contributing to HTTPie
+######################
+
+Bug reports and code and documentation patches are welcome. You can
+help this project also by using the development version of HTTPie
+and by reporting any bugs you might encounter.
+
+1. Reporting bugs
+=================
+
+**It's important that you provide the full command argument list
+as well as the output of the failing command.**
+Use the ``--debug`` flag and copy&paste both the command and its output
+to your bug report, e.g.:
+
+.. code-block:: bash
+
+    $ http --debug [COMPLETE ARGUMENT LIST THAT TRIGGERS THE ERROR]
+    [COMPLETE OUTPUT]
+
+
+2. Contributing Code and Docs
+=============================
+
+Before working on a new feature or a bug, please browse `existing issues`_
+to see whether it has been previously discussed. If the change in question
+is a bigger one, it's always good to discuss before you start working on
+it.
+
+
+Development Environment
+--------------------------------
+
+
+Getting the code
+****************
+
+Go to https://github.com/jakubroztocil/httpie and fork the project repository.
+
+
+.. code-block:: bash
+
+    # Clone your fork
+    git clone git@github.com:<YOU>/httpie.git
+
+    # Enter the project directory
+    cd httpie
+
+    # Create a branch for your changes
+    git checkout -b my_topical_branch
+
+
+Setup
+*****
+
+The `Makefile`_ contains a bunch of tasks to get you started. Just run
+the following command, which:
+
+
+* Creates an isolated Python virtual environment inside ``./venv``
+  (via the standard library `venv`_ tool);
+* installs all dependencies and also installs HTTPie
+  (in editable mode so that the ``http`` command will point to your
+  working copy).
+* and runs tests (It is the same as running ``make install test``).
+
+
+.. code-block:: bash
+
+    make
+
+
+
+Python virtual environment
+**************************
+
+Activate the Python virtual environment—created via the ``make install``
+task during `setup`_—for your active shell session using the following command:
+
+.. code-block:: bash
+
+    source venv/bin/activate
+
+(If you use ``virtualenvwrapper``, you can also use ``workon httpie`` to
+activate the environment — we have created a symlink for you. It’s a bit of
+a hack but it works™.)
+
+You should now see ``(httpie)`` next to your shell prompt, and
+the ``http`` should point to you development copy:
+
+.. code-block::
+
+    (httpie) ~/Code/httpie $ which http
+    /Users/jakub/Code/httpie/venv/bin/http
+    (httpie) ~/Code/httpie $ http --version
+    2.0.0-dev
+
+(Btw, you don’t need to activate the virtual environment if you just want
+run some of the ``make`` tasks. You can also invoke the development
+version of HTTPie directly with ``./venv/bin/http`` without having to activate
+the environment first. The same goes for ``./venv/bin/py.test``, etc.).
+
+
+Making Changes
+--------------
+
+Please make sure your changes conform to `Style Guide for Python Code`_ (PEP8)
+and that ``make pycodestyle`` passes.
+
+
+Testing & CI
+------------
+
+Please add tests for any new features and bug fixes.
+
+When you open a pull request,
+`Github Actions <https://github.com/jakubroztocil/httpie/actions>`_
+will automatically run HTTPie’s `test suite`_ against your code
+so please make sure all checks pass.
+
+
+Running tests locally
+*********************
+
+HTTPie uses the `pytest`_ runner. It also uses `Tox`_ which allows you to run
+tests on multiple Python versions even when testing locally.
+
+
+.. code-block:: bash
+
+    # Run tests on the current Python interpreter with coverage.
+    make test
+
+    # Run tests with coverage
+    make test-cover
+
+    # Run all tests in all of the supported and available Pythons via Tox
+    make test-tox
+
+    # Test PEP8 compliance
+    make pycodestyle
+
+    # Run extended tests — for code as well as .rst files syntax, packaging, etc.
+    make test-all
+
+
+Running specific tests
+**********************
+
+After you have activated your virtual environment (see `setup`_), you
+can run specific tests from the terminal:
+
+.. code-block:: bash
+
+    # Run specific tests on the current Python
+    py.test tests/test_uploads.py
+    py.test tests/test_uploads.py::TestMultipartFormDataFileUpload
+    py.test tests/test_uploads.py::TestMultipartFormDataFileUpload::test_upload_ok
+
+    # Run specific tests on the on all Pythons via Tox
+    # (change to `tox -e py37' to limit Python version)
+    tox -- tests/test_uploads.py --verbose
+    tox -- tests/test_uploads.py::TestMultipartFormDataFileUpload --verbose
+    tox -- tests/test_uploads.py::TestMultipartFormDataFileUpload::test_upload_ok --verbose
+
+-----
+
+See `Makefile`_ for additional development utilities.
+
+
+Finally, don't forget to add yourself to `AUTHORS`_!

+    The response has the following attributes:
+
+        `stdout` is represented by the instance itself (print r)
+        `stderr`: text written to stderr
+        `exit_status`: the exit status
+        `json`: decoded JSON (if possible) or `None`
+
+    Exceptions are propagated.
+
+    If you pass ``tolerate_error_exit_status=True``, then error exit statuses
+    won't result into an exception.
+
+    Example:
+
+    $ http --auth=user:password GET httpbin.org/basic-auth/user/password
+
+        >>> httpbin = getfixture('httpbin')
+        >>> r = http('-a', 'user:pw', httpbin.url + '/basic-auth/user/pw')
+        >>> type(r) == StrCLIResponse
+        True
+        >>> r.exit_status
+        <ExitStatus.SUCCESS: 0>
+        >>> r.stderr
+        ''
+        >>> 'HTTP/1.1 200 OK' in r
+        True
+        >>> r.json == {'authenticated': True, 'user': 'user'}
