+* 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

+  (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)
+---------------------

+######################
+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.
+
+
+Creating Development Environment
+--------------------------------
+
+Go to https://github.com/jakubroztocil/httpie and fork the project repository.
+
+
+.. code-block:: bash
+
+    git clone https://github.com/<YOU>/httpie
+
+    cd httpie
+
+    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
+
+
+Making Changes
+--------------
+
+Please make sure your changes conform to `Style Guide for Python Code`_ (PEP8)
+and that ``make pycodestyle`` passes.
+
+
+Testing
+-------
+
+Before opening a pull requests, please make sure the `test suite`_ passes
+in all of the `supported Python environments`_. You should also add tests
+for any new features and bug fixes.
+
+HTTPie uses `pytest`_ and `Tox`_ for testing.
+
+
+Running all tests:
+******************
+
+.. code-block:: bash
+
+    # Run all tests on the current Python interpreter with coverage
+    make test
+
+    # Run all tests in all of the supported and available Pythons via Tox
+    make test-tox
+
+    # Run all tests for code as well as packaging, etc.
+    make test-all
+
+    # Test PEP8 compliance
+    make pycodestyle
+
+
+Running specific tests:
+***********************
+
+.. 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
