+
+- Issue #17481: inspect.getfullargspec() now uses inspect.signature() API.
+
+- Issue #15304: concurrent.futures.wait() can block forever even if

+Tools/Demos
+-----------
+
+- #Issue 20456: Argument Clinic now observes the C preprocessor conditional
+ compilation statements of the C files it parses. When a Clinic block is
+ inside a conditional code, it adjusts its output to match, including
+ automatically generating an empty methoddef macro.
+
+- #Issue 20456: Cloned functions in Argument Clinic now use the correct
+ name, not the name of the function they were cloned from, for text
+ strings inside generated code.
+
+- #Issue 20456: Fixed Argument Clinic's test suite and "--converters" feature.
+
+- #Issue 20456: Argument Clinic now allows specifying different names
+ for a parameter in Python and C, using "as" on the parameter line.
+
+- Issue #20326: Argument Clinic now uses a simple, unique signature to
+ annotate text signatures in docstrings, resulting in fewer false
+ positives. "self" parameters are also explicitly marked, allowing
+ inspect.Signature() to authoritatively detect (and skip) said parameters.
+
+- Issue #20326: Argument Clinic now generates separate checksums for the
+ input and output sections of the block, allowing external tools to verify
+ that the input has not changed (and thus the output is not out-of-date).
+
+Build
+-----
+
+- Issue #20465: Update SQLite shipped with OS X installer to 3.8.3.
+
+Documentation
+-------------
+
+- Issue #20488: Change wording to say importlib is *the* implementation of
+ import instead of just *an* implementation.
+
+- Issue #6386: Clarify in the tutorial that specifying a symlink to execute
+ means the directory containing the executed script and not the symlink is
+ added to sys.path.

+What's New in Python 3.4.0 Beta 3?
+==================================
+
+Release date: 2014-01-26
+
+Core and Builtins
+-----------------
+
+- Issue #20189: Four additional builtin types (PyTypeObject,
+ PyMethodDescr_Type, _PyMethodWrapper_Type, and PyWrapperDescr_Type)
+ have been modified to provide introspection information for builtins.
+
+- Issue #17825: Cursor "^" is correctly positioned for SyntaxError and
+ IndentationError.
+
+- Issue #2382: SyntaxError cursor "^" is now written at correct position in most
+ cases when multibyte characters are in line (before "^"). This still not
+ works correctly with wide East Asian characters.
+
+- Issue #18960: The first line of Python script could be executed twice when
+ the source encoding was specified on the second line. Now the source encoding
+ declaration on the second line isn't effective if the first line contains
+ anything except a comment. 'python -x' works now again with files with the
+ source encoding declarations, and can be used to make Python batch files
+ on Windows.
+
+Library
+-------
+
+- asyncio: Various improvements and small changes not all covered by
+ issues listed below. E.g. wait_for() now cancels the inner task if
+ the timeout occcurs; tweaked the set of exported symbols; renamed
+ Empty/Full to QueueEmpty/QueueFull; "with (yield from lock)" now
+ uses a separate context manager; readexactly() raises if not enough
+ data was read; PTY support tweaks.
+
+- Issue #20311: asyncio: Add a granularity attribute to BaseEventLoop: maximum
+ between the resolution of the BaseEventLoop.time() method and the resolution
+ of the selector. The granuarility is used in the scheduler to round time and
+ deadline.
+
+- Issue #20311: selectors: Add a resolution attribute to BaseSelector.
+
+- Issue #20189: unittest.mock now no longer assumes that any object for
+ which it could get an inspect.Signature is a callable written in Python.
+ Fix courtesy of Michael Foord.
+
- Issue #20317: ExitStack.__exit__ could create a self-referential loop if an
exception raised by a cleanup operation already had its context set
correctly (for example, by the @contextmanager decorator). The infinite
