+
+
+`2.3.0`_ (2020-10-25)
+-------------------------
+
+* Added support for multipart upload streaming (`#684`_).
+* Added support for body-from-file upload streaming (``http httpbin.org/post @file``).
+* Added ``--chunked`` to allow chunked transfer encoding.
+* Added ``--multipart`` to allow ``multipart/form-data`` encoding for non-file ``--form`` requests as well.
+* Added ``--boundary`` to allow a custom boundary string for ``multipart/form-data`` requests.
+* Added support for combining cookies specified on the CLI and in a session file (`#932`_).
+* Added out of the box SOCKS support with no extra installation (`#904`_).
+* Added ``--quiet, -q`` flag to enforce silent behaviour.
+* Fixed the handling of invalid ``expires`` dates in ``Set-Cookie`` headers (`#963`_).
+* Removed Tox testing entirely (`#943`_).
+
+
+`2.2.0`_ (2020-06-18)
+-------------------------
+
+* Added support for custom content types for uploaded files (`#668`_).
+* Added support for ``$XDG_CONFIG_HOME`` (`#920`_).
+* Added support for ``Set-Cookie``-triggered cookie expiration (`#853`_).
+* Added ``--format-options`` to allow disabling sorting, etc. (`#128`_)
+* Added ``--sorted`` and ``--unsorted`` shortcuts for (un)setting all sorting-related ``--format-options``. (`#128`_)
+* Added ``--ciphers`` to allow configuring OpenSSL ciphers (`#870`_).
+* Added ``netrc`` support for auth plugins. Enabled for ``--auth-type=basic``
+  and ``digest``, 3rd parties may opt in (`#718`_, `#719`_, `#852`_, `#934`_).
+* Fixed built-in plugins-related circular imports (`#925`_).
+
+
+`2.1.0`_ (2020-04-18)
+---------------------
+
+* Added ``--path-as-is`` to bypass dot segment (``/../`` or ``/./``)
+  URL squashing (`#895`_).
+* Changed the default ``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.

+# 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
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+

+to see whether it has previously  been discussed.
+
+If your change alters HTTPie’s behaviour or interface, it's a good idea to
+discuss it before you start working on it.
+
+If you are fixing an issue, the first step should be to create a test case that
+reproduces the incorrect behaviour. That will also help you to build an
+understanding of the issue at hand.
+
+**Pull requests introducing code changes without tests
+will generally not get merged. The same goes for PRs changing HTTPie’s
+behaviour and not providing documentation.**
+
+Conversely, PRs consisting of documentation improvements or tests
+for existing-yet-previously-untested behavior will very likely be merged.
+Therefore, docs and tests improvements are a great candidate for your first
+contribution.
+
+Consider also adding a ``CHANGELOG`` entry for your changes.

+Getting the code
+****************
+
 Go to https://github.com/jakubroztocil/httpie and fork the project repository.
 
 
 .. code-block:: bash
 
-    git clone https://github.com/<YOU>/httpie
+    # 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
 
-    # (Recommended: create a new virtualenv)
 
-    # Install dev. requirements and also HTTPie (in editable mode
-    # so that the `http' command will point to your working copy):
-    make init
+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

+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`` command should point to your 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.).

+*******
+
+If you are on a Windows machine and not able to run ``make``,
+follow the next steps for a basic setup. As a prerequisite, you need to have
+Python 3.6+ installed.
+
+Create a virtual environment and activate it:
+
+.. code-block:: powershell
+
+    python -m venv --prompt httpie venv
+    venv\Scripts\activate
+
+Install HTTPie in editable mode with all the dependencies:
+
+.. code-block:: powershell
+
+    pip install --upgrade -e . -r requirements-dev.txt
+
+You should now see ``(httpie)`` next to your shell prompt, and
+the ``http`` command should point to your development copy:
+
+.. code-block:: powershell
