+What's New in Python 3.4.0 Beta 2?
+==================================
+
+Release date: 2014-01-05
+
+Core and Builtins
+-----------------
+
+- Issue #17432: Drop UCS2 from names of Unicode functions in python3.def.
+
+- Issue #19526: Exclude all new API from the stable ABI. Exceptions can be
+ made if a need is demonstrated.
+
+- Issue #19969: PyBytes_FromFormatV() now raises an OverflowError if "%c"
+ argument is not in range [0; 255].
+
+- Issue #19995: %c, %o, %x, and %X now raise TypeError on non-integer input;
+ reworded docs to clarify that an integer type should define both __int__
+ and __index__.
+
+- Issue #19787: PyThread_set_key_value() now always set the value. In Python
+ 3.3, the function did nothing if the key already exists (if the current value
+ is a non-NULL pointer).
+
+- Issue #14432: Remove the thread state field from the frame structure. Fix a
+ crash when a generator is created in a C thread that is destroyed while the
+ generator is still used. The issue was that a generator contains a frame, and
+ the frame kept a reference to the Python state of the destroyed C thread. The
+ crash occurs when a trace function is setup.
+
+- Issue #19576: PyGILState_Ensure() now initializes threads. At startup, Python
+ has no concrete GIL. If PyGILState_Ensure() is called from a new thread for
+ the first time and PyEval_InitThreads() was not called yet, a GIL needs to be
+ created.
+
+- Issue #17576: Deprecation warning emitted now when __int__() or __index__()
+ return not int instance.
+
+- Issue #19932: Fix typo in import.h, missing whitespaces in function prototypes.
+
+- Issue #19736: Add module-level statvfs constants defined for GNU/glibc
+ based systems.
+
+- Issue #20097: Fix bad use of "self" in importlib's WindowsRegistryFinder.
+
+- Issue #19729: In str.format(), fix recursive expansion in format spec.
+
+- Issue #19638: Fix possible crash / undefined behaviour from huge (more than 2
+ billion characters) input strings in _Py_dg_strtod.
+
+Library
+-------
+
+- Issue #20154: Deadlock in asyncio.StreamReader.readexactly().
+
+- Issue #16113: Remove sha3 module again.
+
+- Issue #20111: pathlib.Path.with_suffix() now sanity checks the given suffix.
+
+- Fix breakage in TestSuite.countTestCases() introduced by issue #11798.
+
- Issue #20108: Avoid parameter name clash in inspect.getcallargs().
-- Issue #12692: Backport the fix for ResourceWarning in test_urllib2net. This
- also helps in closing the socket when Connection Close header is not sent.
+- Issue #19918: Fix PurePath.relative_to() under Windows.
- Issue #19422: Explicitly disallow non-SOCK_STREAM sockets in the ssl
module, rather than silently let them emit clear text data.
