+-----------------
+2014-04-23 3.2.6
+-----------------
+
+* Fixes issue #21291: Popen.wait() is now thread safe so that multiple
+  threads may be calling wait() or poll() on a Popen instance at the same time
+  without losing the Popen.returncode value.
+* Fixes issue #14396: Handle the odd rare case of waitpid returning 0 when not
+  expected in Popen.wait().
+* Fixes issue #16962: Use getdents64 instead of the obsolete getdents syscall
+  on Linux.  Some architectures do not implement the latter.
+
+-----------------
+2013-12-10 3.2.5
+-----------------
+
+* Fixes issue #15798: subprocess.Popen() no longer fails if file
+  descriptor 0, 1 or 2 is closed.
+* Fixes issue #18763: close_fd file descriptors are now closed after
+  any preexec_fn call.
+
+-----------------
+2013-06-15 3.2.5rc1
+-----------------
+
+* Fixes issue #16650 - Don't reference ECHILD from outside the local scope.
+* Unittests no longer spew any test data for human verification to stdout.
+* Remove a bare print to stdout that could have happened if the child process
+  wrote garbage to its pre-exec error pipe.
+* Fixes issue #16327 - the subprocess module no longer leaks file descriptors
+  used for stdin/stdout/stderr pipes to the child when the fork() fails.  It
+  also no longer potentially double closes these pipe fds.
+* Correct the Python version check around use of imp_module to specify 2.6.3
+  as the minimum version that exists in. Why is anyone using such an old 2.6?
+* Fixes Issue #16114: The subprocess module no longer provides a misleading
+  error message stating that args[0] did not exist when either the cwd or
+  executable keyword arguments specified a path that did not exist.
+* Add more Popen cwd tests.
+* Handle errno.ECHILD in poll.
+* Don't leak a reference to the gc module on capi use error.
+* Check return value to avoid a crash if the capi were misused.
+* Check result of PyObject_IsTrue().
+* Adds test_universal_newlines_communicate_input_none.
+* Most everything above consists of backports.  See the hg logs for their
+  upstream hg.python.org cpython revision numbers.
+
+----------------
+2012-06-10 3.2.3
+----------------
+
+* Fixes the references to the 'surrogateescape' unicode encoding error
+  handler that does not exist in Python 2.x.  'strict' is used so that
+  a UnicodeEncodeError exception is raised in these situations.  These
+  MAY occur if your sys.getfilesystemencoding() is not UTF-8 and
+  attempt to use a non-ascii executable, args or env values.  Prior to
+  this change, those would result in a hard to debug LookupError for
+  surrogateescape.
+* Issue #15000: Support the "unique" x32 architecture in _posixsubprocess.c.
+* Fix a compilation problem when O_CLOEXEC is not defined.
+
+------------------
+2012-02-18 3.2.3b1
+------------------
+
+This release brings in the last year and a half's worth of bugfixes and
+improvements to Python 3.2's subprocess module:
+
+Off the top of my head, some major bugfix highlights include:
+ * Timeout support on the APIs.
+ * close_fds=True is now the default (as it is in 3.2) and performs much faster.
+ * Fixed EINTR handling.
+ * Fixed SIGCHLD handling.
+ * Fixed several race conditions.
+ * Many more bug fixes too numerous to list.
+
+You can grep out the full list of improvements related to subprocess in:

+
+-------------
+2010-06 3.2.0
+-------------
+
+This was the first release. Roughly equivalent to Python 3.2.0a1.
