Library
-------
-- Issue #12467: warnings: fix a race condition if a warning is emitted at
- shutdown, if globals()['__file__'] is None.
++- Issues #11104, #8688: Fix the behavior of distutils' sdist command with
++ manually-maintained MANIFEST files.
+
-Tests
------
+- Issue #11281: smtplib.STMP gets source_address parameter, which adds the
+ ability to bind to specific source address on a machine with multiple
+ interfaces. Patch by Paulo Scardine.
-- Skip network tests when getaddrinfo() returns EAI_AGAIN, meaning a temporary
- failure in name resolution.
+- Issue #12464: tempfile.TemporaryDirectory.cleanup() should not follow
+ symlinks: fix it. Patch by Petri Lehtinen.
-- Avoid failing in test_urllibnet.test_bad_address when some overzealous
- DNS service (e.g. OpenDNS) resolves a non-existent domain name. The test
- is now skipped instead.
+- Issue #8887: "pydoc somebuiltin.somemethod" (or help('somebuiltin.somemethod')
+ in Python code) now finds the doc of the method.
+- Issue #10968: Remove indirection in threading. The public names (Thread,
+ Condition, etc.) used to be factory functions returning instances of hidden
+ classes (_Thread, _Condition, etc.), because (if Guido recalls correctly) this
+ code pre-dates the ability to subclass extension types. It is now possible to
+ inherit from Thread and other classes, without having to import the private
+ underscored names like multiprocessing did.
-What's New in Python 3.2.1 release candidate 2?
-===============================================

- links when called from any directory.
+- Issue #12576: Fix urlopen behavior on sites which do not send (or obfuscates)
+ Connection:close header.

- raw_input() interrupted by CTRL+c.

+ with mmap. Patch by Steffen Daode Nurpmeso.
-- Issue #9670: Increase the default stack size for secondary threads on Mac OS X

+ to get channel binding data for the current SSL session (only the
+ "tls-unique" channel binding is implemented). This allows the implementation
+ of certain authentication mechanisms such as SCRAM-SHA-1-PLUS. Patch by
+ Jacek Konieczny.
+
+- Issue #665194: email.utils now has format_datetime and parsedate_to_datetime
+ functions, allowing for round tripping of RFC2822 format dates.
+
+- Issue #12571: Add a plat-linux3 directory mirroring the plat-linux2
+ directory, so that "import DLFCN" and other similar imports work on
+ Linux 3.0.
+
+- Issue #7484: smtplib no longer puts <> around addresses in VRFY and EXPN
+ commands; they aren't required and in fact postfix doesn't support that form.
+
+- Issue #12273: Remove ast.__version__. AST changes can be accounted for by

+ TextIOWrapper to a huge value, not TypeError.
+
+- Issue #12504: Close file handles in a timely manner in packaging.database.
+ This fixes a bug with the remove (uninstall) feature on Windows.
+
+- Issues #12169 and #10510: Factor out code used by various packaging commands
+ to make HTTP POST requests, and make sure it uses CRLF.
+
+- Issue #12016: Multibyte CJK decoders now resynchronize faster. They only
+ ignore the first byte of an invalid byte sequence. For example,
+ b'\xff\n'.decode('gb2312', 'replace') gives '\ufffd\n' instead of '\ufffd'.
+
+- Issue #12459: time.sleep() now raises a ValueError if the sleep length is
+ negative, instead of an infinite sleep on Windows or raising an IOError on
+ Linux for example, to have the same behaviour on all platforms.

+ instead of text mode using the locale encoding, to avoid encoding issues.
+
+- Issue #12451: runpy: run_path() now opens the Python script in binary mode,
+ instead of text mode using the locale encoding, to support other encodings
+ than UTF-8 (scripts using the coding cookie).
+
+- Issue #12451: xml.dom.pulldom: parse() now opens files in binary mode instead
+ of the text mode (using the locale encoding) to avoid encoding issues.
- Issue #12147: Adjust the new-in-3.2 smtplib.send_message method for better
- conformance to the RFCs: correctly handle Sender and Resent headers.
+ conformance to the RFCs: correctly handle Sender and Resent- headers.

++- Issue #12331: The test suite for lib2to3 can now run from an installed
++ Python.
++
+- Issue #12626: In regrtest, allow to filter tests using a glob filter
+ with the ``-m`` (or ``--match``) option. This works with all test cases
+ using the unittest module. This is useful with long test suites
+ such as test_io or test_subprocess.
+

+ running in verbose mode (``-v`` or ``-W``), by using the ``--failfast``
+ (or ``-G``) option to regrtest. This is useful with long test suites
+ such as test_io or test_subprocess.
+

+ Web site.
+
+- Avoid failing in test_urllibnet.test_bad_address when some overzealous
+ DNS service (e.g. OpenDNS) resolves a non-existent domain name. The test
+ is now skipped instead.
+
+- Issue #12440: When testing whether some bits in SSLContext.options can be
+ reset, check the version of the OpenSSL headers Python was compiled against,
+ rather than the runtime version of the OpenSSL library.

+ test_tk or test_ttk_guionly under a username that is not currently logged

+
+- Issue #12400: regrtest -W doesn't rerun the tests twice anymore, but captures

+ test_build_ext of test_distutils and test_command_build_ext of
+ test_packaging are no longer silently skipped when
+ run outside of a build directory.
