+==========================
+ What's new in gevent 1.3
+==========================
+
+Detailed information on what has changed is available in the
+:doc:`changelog`. This document summarizes the most important changes
+since :doc:`gevent 1.2 <whatsnew_1_2>`.
+
+.. caution:: This document has not yet been updated for gevent 1.3.
+
+In general, gevent 1.2 is a smaller update than gevent 1.1, focusing
+on platform support, standard library compatibility, security, bug
+fixes and consistency.
+
+Platform Support
+========================
+
+gevent 1.2 supports Python 2.7, 3.4, 3.5 and 3.6 on the CPython
+(`python.org`_) interpreter. It also supports `PyPy2`_ 4.0.1 and above
+(PyPy2 5.4 or higher is recommended) and PyPy3 5.5.0.
+
+
+.. caution:: Support for Python 2.6 was removed. Support for Python 3.3 is only
+               tested on PyPy3.
+
+.. note:: PyPy is not supported on Windows. (gevent's CFFI backend is not
+         available on Windows.)
+
+Python 3.6 was released recently and is supported at the same level as 3.5.
+
+For ease of installation on Windows and OS X, gevent 1.2 is
+distributed as pre-compiled binary wheels, in addition to source code.
+
+.. _python.org: http://www.python.org/downloads/
+.. _PyPy2: http://pypy.org
+
+Bug Fixes
+=========
+
+Since 1.1.2, gevent 1.2 contains over 240 commits from nine different
+dozen contributors. About two dozen pull requests were merged.
+
+Improved subprocess support
+===========================
+
+In gevent 1.1, subprocess monkey-patching was on by default for the
+first time. Over time this led to discovery of a few issues and corner
+cases that have been fixed in 1.2.
+
+- Setting SIGCHLD to SIG_IGN or SIG_DFL after :mod:`gevent.subprocess`
+  had been used previously could not be reversed, causing
+  ``Popen.wait`` and other calls to hang. Now, if SIGCHLD has been
+  ignored, the next time :mod:`gevent.subprocess` is used this will be
+  detected and corrected automatically. (This potentially leads to
+  issues with :func:`os.popen` on Python 2, but the signal can always
+  be reset again. Mixing the low-level process handling calls,
+  low-level signal management and high-level use of
+  :mod:`gevent.subprocess` is tricky.) Reported in :issue:`857` by
+  Chris Utz.
+- ``Popen.kill`` and ``send_signal`` no longer attempt to send signals
+  to processes that are known to be exited.
+- The :func:`gevent.os.waitpid` function is cooperative in more
+  circumstances. Reported in :issue:`878` by Heungsub Lee.
+
+API Additions
+=============
+
+Numerous APIs offer slightly expanded functionality in this version.
+Look for "changed in version 1.2" or "added in version 1.2" throughout
+the documentation for specifics.
+
+Of particular note, several backwards compatible updates to the
+subprocess module have been backported from Python 3 to Python 2,
+making :mod:`gevent.subprocess` smaller, easier to maintain and in
+some cases safer, while letting gevent clients use the updated APIs
+even on older versions of Python.
+
+If ``concurrent.futures`` is available (Python 3, or if the Python 2
+backport has been installed), then the class
+:class:`gevent.threadpool.ThreadPoolExecutor` is defined to create an
+executor that always uses native threads, even when the system is
+monkey-patched.
+
+Library Updates
+===============
+
+The two C libraries that are bundled with gevent have been updated.
+libev has been updated from 4.20 to 4.23 (`libev release notes`_) and
+c-ares has been updated from 1.10.0 to 1.12.0 (`c-ares release notes`_).
+
+
+.. _libev release notes: https://github.com/gevent/gevent/blob/master/deps/libev/Changes
+.. _c-ares release notes: https://c-ares.haxx.se/changelog.html
+
+Compatibility
+=============
+
+This release is intended to be compatible with 1.1.x with no changes
+to client source code, so long as only non-deprecated and supported
+interfaces were used (as always, internal, non-documented
+implementation details may have changed).
+
+In particular the deprecated ``gevent.coros`` module has been removed
+and ``gevent.corecext`` and ``gevent.corecffi`` have also been removed.
+
+For security, ``gevent.pywsgi`` no longer accepts incoming headers
+containing an underscore, and header values passed to
+``start_response`` cannot contain a carriage return or newline. See
+:issue:`819` and :issue:`775`, respectively.
