-
-What's New in Python 2.6.5 rc 1?
-================================
-
-*Release date: 2010-03-01*
+- Issue #17477: Update the bsddb module to pybsddb 5.3.0, supporting
+  db-5.x, and dropping support for db-4.1 and db-4.2.
+
+- Issue #17192: Update the ctypes module's libffi to v3.0.13.  This
+  specifically addresses a stack misalignment issue on x86 and issues on
+  some more recent platforms.
+
+- Issue #12268: The io module file object write methods no longer abort early
+  when a write system calls is interrupted (EINTR).
+
+- Fix the leak of a dict in the time module when used in an embedded
+  interpreter that is repeatedly initialized and shutdown and reinitialized.
+
+- Issue #12268: File readline, readlines and read or readall methods
+  no longer lose data when an underlying read system call is interrupted
+  within an io module object.  IOError is no longer raised due to a read
+  system call returning EINTR from within these methods.
+
+- Issue #16012: Fix a regression in pyexpat. The parser's UseForeignDTD()
+  method doesn't require an argument again.
+
+- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
+  In particular, fix extension module build failures when trying to use
+  32-bit-only installer Pythons on systems with Xcode 4 (currently
+  OS X 10.8, 10.7, and optionally 10.6).
+  * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
+  * Since Xcode 4 removes ppc support, extension module builds now
+    check for ppc compiler support and by default remove ppc and
+    ppc64 archs when they are not available.
+  * Extension module builds now revert to using system installed
+    headers and libs (/usr and /System/Library) if the SDK used
+    to build the interpreter is not installed or has moved.
+  * Try to avoid building extension modules with deprecated
+    and problematic Apple llvm-gcc compiler.  If original compiler
+    is not available, use clang instead by default.

+  by David Malcolm, based on work by Victor Stinner.
+
+- Issue #11235: Fix OverflowError when trying to import a source file whose
+  modification time doesn't fit in a 32-bit timestamp.
+
+- Issue #11638: Unicode strings in 'name' and 'version' no longer cause

+
+- Fix the fix for issue #12149: it was incorrect, although it had the side

+  noticing.
+
+- Issue #13546: Fixed an overflow issue that could crash the intepreter when
+  calling sys.setrecursionlimit((1<<31)-1).

+
+- Issue #12973: Fix overflow checks that invoked undefined behaviour in
+  int.__pow__.  These overflow checks were causing int.__pow__ to produce
+  incorrect results with recent versions of Clang, as a result of the
+  compiler optimizing the check away.  Also fix similar overflow checks
+  in list_repeat (listobject.c) and islice_next (itertoolsmodule.c).  These

+
+- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
+  has left two versions of customize_compiler, the original in
+  distutils.sysconfig and another copy in distutils.ccompiler, with some
+  parts of distutils calling one and others using the other.
+  Complete the revert back to only having one in distutils.sysconfig as

+
+- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
+  Distutils-based packages with C extension modules may fail because
+  Apple has removed gcc-4.2, the version used to build python.org
+  64-bit/32-bit Pythons.  If the user does not explicitly override
+  the default C compiler by setting the CC environment variable,
+  Distutils will now attempt to compile extension modules with clang
+  if gcc-4.2 is required but not found. Also as a convenience, if
+  the user does explicitly set CC, substitute its value as the default
+  compiler in the Distutils LDSHARED configuration variable for OS X.
+  (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
+  SDK, neither of which are available in Xcode 4.  This change does not
+  attempt to override settings to support their use with Xcode 4.)
+
+- Issue #9021: Add an introduction to the copy module documentation.

+
+- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
+  check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
+  interpreter process.  This could cause failures in non-Distutils subprocesses
+  and was unreliable since tests or user programs could modify the interpreter
+  environment after Distutils set it.  Instead, have Distutils set the
+  deployment target only in the environment of each build subprocess.  It is
+  still possible to globally override the default by setting
+  MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
+  greater or equal to the default value, the value with which the interpreter
+  was built.

+  some corner-case Decimal.__pow__ calls to take an unreasonably long time.
+
+- Named tuples now work correctly with vars().
+
+- sys.setcheckinterval() now updates the current ticker count as well as
+  updating the check interval, so if the user decreases the check interval,
+  the ticker doesn't have to wind down to zero from the old starting point
+  before the new interval takes effect.  And if the user increases the
+  interval, it makes sure the new limit takes effect right away rather have an
+  early task switch before recognizing the new interval.
+
+- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the
+  constructor has failed, e.g. because of an undeclared keyword argument. Patch
+  written by Oleg Oshmyan.

+
+- Issue #10674: Remove unused 'dictmaker' rule from grammar.

+- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
+  SSLSocket.sendto() to match the corresponding socket methods.  Also,
+  fix various SSLSocket methods to raise socket.error rather than an
+  unhelpful TypeError when called on an unconnected socket.  Original patch
+  by Andrew Bennetts.
+
+- Issue #9826: OrderedDict.__repr__ can now handle self-referential
+  values:   d['x'] = d.
+
+- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
+
+- Issue #9837: The read() method of ZipExtFile objects (as returned by
+  ZipFile.open()) could return more bytes than requested.
+
+- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
+  This prevents user-created self-referencing ordered dictionaries from
+  becoming permanently uncollectable GC garbage.  The downside is that
+  removing __del__ means that the internal doubly-linked list has to wait for
+  GC collection rather than freeing memory immediately when the refcnt drops
+  to zero.
+
+- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
+  different internal state for small values of n.  Fixed by salting the
+  value.
+
+- Issue #9792: In case of connection failure, socket.create_connection()
+  would swallow the exception and raise a new one, making it impossible
+  to fetch the original errno, or to filter timeout errors.  Now the
+  original error is re-raised.
+
+- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
+  and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
+  be updated back after the system call.  Original patch by Brian Brazil.
+
+- Issue #1100562: Fix deep-copying of objects derived from the list and
+  dict types.  Patch by Michele Orrù and Björn Lindqvist.
+
+- Issue #7005: Fixed output of None values for RawConfigParser.write and
+  ConfigParser.write.
+
+- Issue #808164: Fixed socket.close to avoid references to globals, to
+  avoid issues when socket.close is called from a __del__ method.
+
+- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
+  can be set to False to turn off the previously undocumented 'popularity'
+  heuristic. Patch by Terry Reedy and Eli Bendersky
+
+- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
+  falling into recursion.
+
+- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
+  character years even if the message contains RFC822 two character years.
+
+- Issue #8750: Fixed MutableSet's methods to correctly handle
+  reflexive operations, namely x -= x and x ^= x.
+
+- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
+  error handling when accepting a new connection.
+
+- Issue #658749: asyncore's connect() method now correctly interprets winsock
+  errors.
+
+- Issue #9501: Fixed logging regressions in cleanup code.
+
+- Issue #9214: Set operations on KeysView or ItemsView in the collections
+  module now correctly return a set.  (Patch by Eli Bendersky.)
+
+- Issue #9617: Signals received during a low-level write operation aren't
+  ignored by the buffered IO layer anymore.
+
+- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
+  are not held onto after they are deleted elsewhere.
+
+- Issue #9626: the view methods for collections.OrderedDict() were returning
+  the unordered versions inherited from dict.  Those methods are now
+  overridden to provide ordered views.
+
+- Issue #8688: MANIFEST files created by distutils now include a magic
+  comment indicating they are generated.  Manually maintained MANIFESTs
+  without this marker will not be overwritten or removed.
+
+- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
+  and a BadZipfile error is raised if it doesn't match (as used to be the
+  case in Python 2.5 and earlier).
+
+- Issue #9550: a BufferedReader could issue an additional read when the
+  original read request had been satisfied, which could block indefinitely
+  when the underlying raw IO channel was e.g. a socket.  Report and original
+  patch by Jason V. Miller.
+
+- Issue #9551: Don't raise TypeError when setting the value to None for
+  SafeConfigParser instances constructed with allow_no_value == True.
+
+- Issue #6915: Under Windows, os.listdir() didn't release the Global
+  Interpreter Lock around all system calls.  Original patch by Ryan Kelly.
+
+- Issue #3757: thread-local objects now support cyclic garbage collection.
+  Thread-local objects involved in reference cycles will be deallocated
+  timely by the cyclic GC, even if the underlying thread is still running.
+
+- Issue #6231: Fix xml.etree.ElementInclude to include the tail of the
+  current node.
+
+- Issue #6869: Fix a refcount problem in the _ctypes extension.
+
+- Issue5504 - ctypes should now work with systems where mmap can't be
+  PROT_WRITE and PROT_EXEC.
+
+- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
+  This is how it is supposed to work, wget and curl do the same.  Previous
+  behavior was wrong.
+
+- Issue #2944: asyncore doesn't handle connection refused correctly.
+
+- Issue #3196: email header decoding is now forgiving if an RFC2047
+  encoded word encoded in base64 is lacking padding.
+
+- Issue #9444: Argparse now uses the first element of prefix_chars as
+  the option character for the added 'h/help' option if prefix_chars
+  does not contain a '-', instead of raising an error.
+
+- Issue #9354: Provide getsockopt() in asyncore's file_wrapper.
+
+- Issue #9428: Fix running scripts with the profile/cProfile modules from
+  the command line.
+
+- Issue #7781: Fix restricting stats by entry counts in the pstats
+  interactive browser.

+  XML-RPC request.
+
+- Issue #5542: Remove special logic that closes HTTPConnection socket on EPIPE.
+
+- Issue #4629: getopt raises an error if an argument ends with = whereas getopt

+  options).
+
+- Issue #7895: platform.mac_ver() no longer crashes after calling os.fork()
+

+  (Jan Hosang).
+
+- Issue #7646: The fnmatch pattern cache no longer grows without bound.
+
+- Issue #9136: Fix 'dictionary changed size during iteration'
+  RuntimeError produced when profiling the decimal module.  This was
+  due to a dangerous iteration over 'locals()' in Context.__init__.
+
+- Fix extreme speed issue in Decimal.pow when the base is an exact
+  power of 10 and the exponent is tiny (for example,

+
+What's New in Python 2.7 Release Candidate 1?
+=============================================
+
+*Release date: 2010-06-05*
+
+Core and Builtins
+-----------------
+
+- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
+  start byte and the continuation byte(s) are now considered invalid, instead
+  of the number of bytes specified by the start byte.
+  E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
+  replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
+  ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
+  Previous versions returned a single u'\ufffd'.
+
+- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
+  __hash__ in 3.x" warning.  Also fix "XXX undetected error" that
+  arises from the "Overriding __eq__ blocks inheritance ..." warning
+  when turned into an exception: in this case the exception simply
+  gets ignored.
+
+- Issue #8748: Fix two issues with comparisons between complex and integer
+  objects.  (1) The comparison could incorrectly return True in some cases
+  (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
+  (2) The comparison raised an OverflowError for large integers, leading
+  to unpredictable exceptions when combining integers and complex objects
+  in sets or dicts.
+
+- Issue #5211: Implicit coercion for the complex type is now completely
+  removed.  (Coercion for arithmetic operations was already removed in 2.7
+  alpha 4, but coercion for rich comparisons was accidentally left in.)
+
+- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
+  and error handler, instead of writing to the C stderr file in utf-8
+
+- Issue #7902: When using explicit relative import syntax, don't try implicit
+  relative import semantics.
+
+- Issue #7079: Fix a possible crash when closing a file object while using it
+  from another thread.  Patch by Daniel Stutzbach.
+
+- Issue #8868: Fix that ensures that python scripts have access to the
+  Window Server again in a framework build on MacOSX 10.5 or earlier.
+
+C-API
+-----
+
+- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
+  of the interpreter to set sys.argv without also modifying sys.path.  This
+  helps fix `CVE-2008-5983
+  <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
+
+Library
+-------

+
+- Issue #8688: Distutils now recalculates MANIFEST every time.
+
+- Issue #5099: The ``__del__()`` method of ``subprocess.Popen`` (and the methods
+  it calls) referenced global objects, causing errors to pop up during
+  interpreter shutdown.
+
+Extension Modules
+-----------------
+
+- Issue #7384: If the system readline library is linked against ncurses,
+  the curses module must be linked against ncurses as well. Otherwise it
+  is not safe to load both the readline and curses modules in an application.
+
+- Issue #2810: Fix cases where the Windows registry API returns
+  ERROR_MORE_DATA, requiring a re-try in order to get the complete result.
+
+- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
+  overflow checks in the ``audioop`` module.

+
+- Issue #8835: test_support.transient_internet() catches gaierror(EAI_NONAME)
+  and gaierror(EAI_NODATA)
+
+- Issue #7449: Skip test_socketserver if threading support is disabled
+
+- On darwin, ``test_site`` assumed that a framework build was being used,

+
+Core and Builtins
+-----------------
+
+- Run Clang 2.7's static analyzer for ``Objects/`` and ``Python/``.
+
+- Issue #1533: Fix inconsistency in range function argument processing: any
+  non-float non-integer argument is now converted to an integer (if possible)
+  using its __int__ method.  Previously, only small arguments were treated this
+  way; larger arguments (those whose __int__ was outside the range of a C long)
+  would produce a TypeError.
+
+- Issue #8202: ``sys.argv[0]`` is now set to '-m' instead of '-c' when searching
+  for the module file to be executed with the -m command line option.
+
+- Issue #7319: When -Q is used, do not silence DeprecationWarning.
+
+- Issue #7332: Remove the 16KB stack-based buffer in

+
+- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
+  passed to bytearray.

+- Issue #8313: ``traceback.format_exception_only()`` encodes unicode message to
+  ASCII with backslashreplace error handler if ``str(value)`` failed.
+
+- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
+  operation raises multiple signals and more than one of those signals is

+
+- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test

+
+- Issue #5103: SSL handshake would ignore the socket timeout and block
+  indefinitely if the other end didn't respond.
+
+- The do_handshake() method of SSL objects now adjusts the blocking mode of the
+  SSL structure if necessary (as other methods already do).
+
+- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.

+  Initial patch by Péter Szabó.
+
+- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
+  string "python" as the *ident*.  openlog() arguments are all optional and
+  keywords.
+
+- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
+  non-infinite timeout.  Also make that method friendlier with applications
+  wanting to continue using the socket in clear-text mode, by disabling

+-----
+
+- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
+  (Optimization was unintentionally turned on in gcc --with-pydebug builds in
+  2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's

+
+What's New in Python 2.7 beta 1?
+================================
+
+*Release date: 2010-04-10*
+
+Core and Builtins
+-----------------
+
+- Issue #7301: Add environment variable $PYTHONWARNINGS.
+
+- Issue #8329: Don't return the same lists from select.select when no fds are
+  changed.
+
+- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
+  on 64-bit machines.  The shift count for either left or right shift is
+  permitted to be up to sys.maxsize.
+
+- Ensure that tokenization of identifiers is not affected by locale.
+
+- Issue #1222585: Added LDCXXSHARED for C++ support.  Patch by Arfrever.
+
+- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
+
+- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
+  with a non-empty format string. This is an effort to future-proof user
+  code. If a derived class does not currently implement __format__ but later
+  adds its own __format__, it would most likely break user code that had
+  supplied a format string. This will be changed to a DeprecationWarning in
+  Python 3.3 and it will be an error in Python 3.4.
+
+- Issue #8268: Old-style classes (not just instances) now support weak
+  references.
+
+- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
+  is set.
+
+- Issue #1583863: An unicode subclass can now override the __unicode__ method
+
+- Issue #6474: Make error message from passing an inadequate number of keyword
+  arguments to a function correct.
+
+- Issue #8164: Don't allow lambda functions to have a docstring.
+
+- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
+  (SIGINT).  If an error occurs while importing the site module, the error is
+  printed and Python exits.  Initialize the GIL before importing the site
+  module.
+
+- Code objects now support weak references.
+
+Library
+-------
+
+- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
+
+- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
+  using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
+  `ssl.OPENSSL_VERSION_NUMBER`.
+
+- Issue #8310: Allow dis to examine new style classes.
+
+- Issue #8257: The Decimal construct now accepts a float instance directly,
+  converting that float to a Decimal of equal value:
+
+     >>> Decimal(1.1)
+     Decimal('1.100000000000000088817841970012523233890533447265625')
+
+- collections.Counter() now supports a subtract() method.
+
+- The functools module now has a total_ordering() class decorator to simplify
+  the specification of rich comparisons.
+
+- The functools module also adds cmp_to_key() as a tool to transition old-style
+  comparison functions to new-style key-functions.
+
+- Issue #8294: The Fraction constructor now accepts Decimal and float instances
+  directly.
+
+- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
+  InvalidOperation instead of returning False.  (Comparisons involving a quiet
+  NaN are unchanged.)  Also, Decimal quiet NaNs are now hashable; Decimal
+  signaling NaNs remain unhashable.
+
+- Issue #2531: Comparison operations between floats and Decimal instances now
+  return a result based on the numeric values of the operands; previously they
+  returned an arbitrary result based on the relative ordering of id(float) and
+  id(Decimal).
+
+- Issue #8233: When run as a script, py_compile.py optionally takes a single
+  argument `-` which tells it to read files to compile from stdin.  Each line is
+  read on demand and the named file is compiled immediately.  (Original patch by
+  Piotr OÅŒarowski).
+
+- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
+  function like a normal call.
+
+- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
+  form feed (0x0C) are now considered linebreaks, as specified in Unicode
+  Standard Annex #14.  See issue #7643.  http://www.unicode.org/reports/tr14/
+
+- Comparisons using one of <, <=, >, >= between a complex instance and a
+  Fractions instance now raise TypeError instead of returning True/False.  This
+  makes Fraction <=> complex comparisons consistent with int <=> complex, float
+  <=> complex, and complex <=> complex comparisons.
+
+- Addition of ``WeakSet`` to the ``weakref`` module.
+
+- logging: Added LOG_FTP to SysLogHandler and updated documentation.
+
+- Issue #8205: Remove the "Modules" directory from sys.path when Python is
+  running from the build directory (POSIX only).
+
+- Issue #7667: Fix doctest failures with non-ASCII paths.
+
+- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
+  didn't support chflags() (for example ZFS under FreeBSD).  The error is now
+  silenced.
+
+- Issue #7703: ctypes supports both buffer() and memoryview().  The former is
+  deprecated.
+
+- Issue #7860: platform.uname now reports the correct 'machine' type when Python
+  is running in WOW64 mode on 64 bit Windows.
+
+- logging: Added getChild utility method to Logger and added isEnabledFor method
+  to LoggerAdapter.
+
+- Issue #8201: logging: Handle situation of non-ASCII and Unicode logger names
+  existing at the same time, causing a Unicode error when configuration code
+  attempted to sort the existing loggers.
+
+- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
+  when logging occurs.
+
+- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
+  Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
+  reads and writes are always retried by OpenSSL itself.
+
+- Issue #8179: Fix macpath.realpath() on a non-existing path.
+
+- Issue #8024: Update the Unicode database to 5.2.
+
+- Issue #8104: socket.recv_into() and socket.recvfrom_into() now support writing
+  into objects supporting the new buffer API, for example bytearrays or
+  memoryviews.
+
+- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
+  with Tcl/Tk-8.5.
+
+- Issue #8140: Extend compileall to compile single files.  Add -i option.
+
+- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of the
+  locale.
+
+- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set
+  to an non existent program name and Python is unable to retrieve the real
+  program name.
+
+- Issue #8117: logging: Improved algorithm for computing initial rollover time
+  for ``TimedRotatingFileHandler`` by using the modification time of an existing
+  log file to compute the next rollover time.  If the log file does not exist,
+  the current time is used as the basis for the computation.
+
+- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3.  The
+  cElementTree module is updated too.
+
+- Issue #7880: Fix sysconfig when the python executable is a symbolic link.
+
+- Issue #7624: Fix ``isinstance(foo(), collections.Callable)`` for old-style
+  classes.
+
+- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
+  a base64 transfer-encoded payload *after* decoding it; it no longer does.
+  This is a behavior change, so email's minor version number is now bumped, to
+  version 4.0.2, for the 2.7 release.
+
+- Issue #8235: _socket: Add the constant ``SO_SETFIB``.  SO_SETFIB is
+  a socket option available on FreeBSD 7.1 and newer.
+
+- Issue #8038: unittest.TestCase.assertNotRegexpMatches
+
+- Addition of -b command line option to unittest for buffering stdout / stderr
+  during test runs.
+
+- Issue #1220212: Added os.kill support for Windows, including support for
+  sending CTRL+C and CTRL+BREAK events to console subprocesses.
+
+Extension Modules
+-----------------
+
+- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
+
+- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.

+  support for Berkeley DB 4.0, and adds support for 4.8.
+
+- Issue #3928: os.mknod() now available in Solaris, also.
+
+- Issue #8142: Update libffi to the 3.0.9 release.
+
+- Issue #8300: When passing a non-integer argument to struct.pack with any
+  integer format code, struct.pack first attempts to convert the non-integer
+  using its __index__ method.  If that method is non-existent or raises
+  TypeError it goes on to try the __int__ method, as described below.
+
+- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
+  integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
+  argument's __int__ method to convert to an integer before packing.  It also
+  produces a DeprecationWarning in this case.  (In Python 2.6, the behaviour was
+  inconsistent: __int__ was used for some integer codes but not for others, and
+  the set of integer codes for which it was used differed between native packing
+  and standard packing.)
+
+- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a bug in
+  the return value of QueryReflectionKey.
+
+Tools/Demos
+-----------
+
+- Issue #7993: Add a test of IO packet processing bandwidth to ccbench.  It
+  measures the number of UDP packets processed per second depending on the

+
+Build
+-----
+
+- Issue #8032: For gdb7, a python-gdb.py file is added to the build, allowing to
+  use advanced gdb features when debugging Python.
+
+- Issue #1628484: The Makefile doesn't ignore the CFLAGS environment variable
+  anymore.  It also forwards the LDFLAGS settings to the linker when building a
+  shared library.
+
+- Issue #6716: Quote -x arguments of compileall in MSI installer.
+
+- Issue #7705: Fix linking on FreeBSD.
+
+- Make sure that the FreeBSD build of the included libffi uses the proper
+  assembly file.
+
+C-API
+-----
+
+- Issue #8276: PyEval_CallObject() is now only available in macro form.  The
+  function declaration, which was kept for backwards compatibility reasons, is
+  now removed (the macro was introduced in 1997!).
+
+- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported from
+  Python 3.1.  All existing Python CObjects in the main distribution have been
+  converted to capsules.  To address backwards-compatibility concerns,
+  PyCObject_AsVoidPtr() was changed to understand capsules.
+
+Tests
+-----
+
+- Issue #3864: Skip three test_signal tests on freebsd6 because they fail if any
+  thread was previously started, most likely due to a platform bug.
+

+  wherever a Decimal instance is accepted, and implicitly convert that argument
+  to Decimal.  Previously only some arguments were converted.
+
+- Issue #6003: Add an argument to ``zipfile.Zipfile.writestr`` to specify the
+  compression type.
+
+- Issue #7893: ``unittest.TextTestResult`` is made public and a ``resultclass``

+  -1 parameter on some platforms such as OS X.
+
+Tests
+-----

+
+Core and Builtins
+-----------------
 
 - Issue #5677: Explicitly forbid write operations on read-only file objects,
   and read operations on write-only file objects.  On Windows, the system C
-  library would return a bogus result; on Solaris, it was possible to crash
-  the interpreter.  Patch by Stefan Krah.
-
-- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
-
-- Issue #7819: Check sys.call_tracing() arguments types.

-  slice with very large step value.
-
-- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
-  could crash in many places because of the PyByteArray_AS_STRING() macro
-  returning NULL.  The macro now returns a statically allocated empty
-  string instead.
+  library would return a bogus result; on Solaris, it was possible to crash the
+  interpreter.  Patch by Stefan Krah.
+
+- Issue #7853: Normalize exceptions before they are passed to a context
+  manager's ``__exit__()`` method.

+- Issue #7788: Fix an interpreter crash produced by deleting a list slice with
+  very large step value.
+
+- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
+  and add the additional members returned in an OSVERSIONINFOEX structure.  The
+  new members are service_pack_major, service_pack_minor, suite_mask, and
+  product_type.
+
+- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
+  could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
+  returning NULL.  The macro now returns a statically allocated empty string

+
+- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
+  methods of bytes, bytearray and unicode objects by using a common
+  implementation based on stringlib's fast search.  Patch by Florent Xicluna.
+
+- Issue #7632: Fix various str -> float conversion bugs present in 2.7 alpha 2,
+  including:
+
+  (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
+      strings,
+  (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
+      numeric strings corresponding to subnormal values,
+  (3) a memory leak for some values large enough to cause overflow, and
+  (4) a number of flaws that could lead to incorrectly rounded results.
+

+  interpreter shutdown.
+
+- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

+  type is specified.  Patch by Brian Curtin.
+
+- logging: Implemented PEP 391.
+
+- Issue #6939: Fix file I/O objects in the `io` module to keep the original
+  file position when calling `truncate()`.  It would previously change the file
+  position to the given argument, which goes against the tradition of
+  ftruncate() and other truncation APIs.  Patch by Pascal Chambon.
+
+- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
+  class used to represent files stored inside an archive.  The new
+  implementation is significantly faster and can be wrapped in a
+  ``io.BufferedReader`` object for more speedups.  It also solves an issue
+  where interleaved calls to ``read()`` and ``readline()`` give wrong results.
+  Patch by Nir Aides.
+
+- Issue #7792: Registering non-classes to ABCs raised an obscure error.
+

+- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
+  when the release file is empty.
+
+- Issue #7748: Since unicode values are supported for some metadata options in
+  Distutils, the DistributionMetadata get_* methods will now return an utf-8
+  encoded string for them.  This ensures that the upload and register commands
+  send the correct values to PyPI without any error.
+
+- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
+  headers in multipart/signed MIME parts, which fixes one of the sources of
+  invalid modifications to such parts by Generator.
+
+- Issue #7701: Fix crash in ``binascii.b2a_uu()`` in debug mode when given a

+
+- Issue #5827: Make sure that normpath preserves unicode.  Initial patch by
+  Matt Giuca.
+
+- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

+  Initial patch by Collin Winter.
+
+Extension Modules
+-----------------
+
+- Expat: Fix DoS via XML document with malformed UTF-8 sequences

+  Patch by Florent Xicluna.
+
+Tools/Demos
+-----------
+
+- iobench (a file I/O benchmark) and ccbench (a concurrency benchmark) were
+  added to the ``Tools`` directory.  They were previously living in the
+  sandbox.
+
+Tests
+-----
+
+- Issue #7728: test_timeout was changed to use ``test_support.bind_port()``
+  instead of a hard coded port.
+
+Documentation
+-------------
+
+- Updated "Using Python" documentation to include description of CPython's -J,

+=================================
+
+*Release date: 2010-01-09*

+  make it consistent with other special methods.
+
+- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
+  `rindex`, `rsplit` and `rpartition` methods.  Patch by Florent Xicluna.

+  DeprecationWarning when passed a float argument where an integer was expected.
+  These functions and methods now raise TypeError instead.  The majority of the
+  effects of this change are in the extension modules, but some core functions
+  and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
+  and many unicode/str methods.
 
 - Issue #7604: Deleting an unset slotted attribute did not raise an
   AttributeError.

+  least on IEEE 754 platforms), and in particular does not depend on the
+  internal representation of a long.
+
+- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
+  same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
+  in the subclass.
+
+- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
+  executables on OSX.

+- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
+  when called with invalid values.
+
+- Issue #3382: 'F' formatting for float and complex now convert the result to
+  upper case.  This only affects 'inf' and 'nan', since 'f' no longer converts
+  to 'g' for large values.
+
+- Remove switch from "%f" formatting to "%g" formatting for floats larger than
+  1e50 in absolute value.
+
+- Remove restrictions on precision when formatting floats.  E.g., "%.120g" %
+  1e-100 used to raise OverflowError, but now gives the requested 120
+  significant digits instead.
+
+- Add Py3k warnings for parameter names in parentheses.
+
+- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
+
+- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
+  10.6.
+
+- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
+  decimal string that's guaranteed to round back to x under correct rounding
+  (with round-half-to-even rounding mode).  Previously it gave a string based on
+  rounding x to 17 decimal digits.  repr(x) for a complex number behaves
+  similarly.  On platforms where the correctly-rounded strtod and dtoa code is
+  not supported (see below), repr is unchanged.
+
+- Issue #7117: On almost all platforms: float-to-string and string-to-float
+  conversions within Python are now correctly rounded.  Places these conversions
+  occur include: str for floats and complex numbers; the float and complex
+  constructors; old-style and new-style numeric formatting; serialization and
+  deserialization of floats and complex numbers using marshal, pickle and json;
+  parsing of float and imaginary literals in Python code; Decimal-to-float
+  conversion.
+
+  The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
+  providing correctly-rounded strtod and dtoa C functions.  This code is
+  supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
+  the C compiler.  There may be a small number of platforms on which correct
+  operation of this code cannot be guaranteed, so the code is not used: notably,
+  this applies to platforms where the C double format is not IEEE 754 binary64,
+  and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
+  and Python's configure script is unable to determine how to change the FPU
+  precision.  On these platforms conversions use the platform strtod and dtoa,
+  as before.
+
+- Issue #7117: Backport round implementation from Python 3.x.  ``round()`` now
+  uses the correctly-rounded string <-> float conversions described above (when
+  available), and so produces correctly rounded results that will display nicely
+  under the float repr.  There are two related small changes: (1) round now
+  accepts any class with an ``__index__()`` method for its second argument (but
+  no longer accepts floats for the second argument), and (2) an excessively
+  large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
+  raises an exception.
+
+- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
+
+- Fix several issues with ``compile()``.  The input can now contain Windows and
+  Mac newlines and is no longer required to end in a newline.
+
+- Remove length limitation when constructing a complex number from a unicode
+  string.
+
+- Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised
+  during the formation of an output tuple.
+
+- Issue #1087418: Boost performance of bitwise operations for longs.
+
+- Issue #1722344: ``threading._shutdown()`` is now called in ``Py_Finalize()``,
+  which fixes the problem of some exceptions being thrown at shutdown when the
+  interpreter is killed.  Patch by Adam Olsen.
+
+- Issue #7168: Document ``PyFloat_AsString()`` and ``PyFloat_AsReprString()``,
+  and note that they are unsafe and deprecated.
+
+- Issue #7120: logging: Remove import of multiprocessing which is causing crash
+  in GAE.
+
+- Issue #7140: The ``__dict__`` of a module should not be cleared unless the
+  module is the only object holding a reference to it.
+
+- Issue #1754094: Improve the stack depth calculation in the compiler.  There
+  should be no other effect than a small decrease in memory use.  Patch by
+  Christopher Tur Lesniewski-Laas.
+
+- Issue #7084: Fix a (very unlikely) crash when printing a list from one thread,
+  and mutating it from another one.  Patch by Scott Dial.
+
+- Issue #1571184: The Unicode database contains properties for more characters.
+  The tables for code points representing numeric values, white spaces or line
+  breaks are now generated from the official Unicode Character Database files,
+  and include information from the Unihan.txt file.
+
+- Issue #7050: Fix a SystemError when trying to use unpacking and augmented
+  assignment.
+
+- Issue #5329: Fix ``os.popen*`` regression from 2.5 with commands as a sequence
+  running through the shell.  Patch by Jean-Paul Calderone and Jani Hakala.
+
+- Issue #7019: Raise ValueError when unmarshalling bad long data, instead of
+  producing internally inconsistent Python longs.
+
+- Issue #6990: Fix ``threading.local`` subclasses leaving old state around after

+
+- Issue #6300: unicode.encode, unicode.decode, str.decode, and str.encode now
+  take keyword arguments.
+
+- Issue #6922: Fix an infinite loop when trying to decode an invalid UTF-32
+  stream with a non-raising error handler like "replace" or "ignore".
+
+- Issue #6713: Improve performance of base 10 int -> string and long -> string
+  conversions.

+
+- Issue #4688: Add a heuristic so that tuples and dicts containing only
+  untrackable objects are not tracked by the garbage collector. This can reduce

+  150% faster.
+
+- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the

+
+- Running Python with the -3 option now also warns about classic division for
+  ints and longs.
+
+- Issue #5260: Long integers now consume less memory: average saving is 2 bytes

+
+- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
+  rotating the object pointer by 4 bits to the right.
+
+- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs: it now
+  forces its argument to double before testing for infinity.
+
+- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
+
+- Issue #1242657: the __len__() and __length_hint__() calls in several tools

+
+- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
+  OSError.
+
+- Issue #4807: Port the _winreg module to Windows CE.
+
+- Issue #4935: The overflow checking code in the expandtabs() method common to

+
+- Issue #4893: Use NT threading on CE.
+
+- Issue #4915: Port sysmodule to Windows CE.
+
+- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
+  collecting the oldest generation) so that allocating lots of objects without
+  destroying them does not show quadratic performance. Based on a proposal by
+  Martin von Löwis at
+  http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
+
+- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
+
+- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
+  existing .py counterpart, override the co_filename attributes of all code

+
+- Issue #4445: Replace ``sizeof(PyStringObject)`` with
+  ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
+  instances.  On a typical machine this saves 3 bytes of memory (on average) per

+
+- Issue #4069: When ``set.remove(element)`` is used with a set element, the
+  element is temporarily replaced with an equivalent frozenset.  But the

+
+- Some PyBytes_* aliases have been removed because they don't exist in 3.x.
+
+- Issue #5175: PyLong_AsUnsignedLongLong now raises OverflowError for negative
+  arguments.  Previously, it raised TypeError.

-- Fix expat to not segfault with specially crafted input.
+- Fix a segfault in expat when given a specially crafted input lead to the
+  tokenizer not stopping. CVE-2009-3720.
+
+- Issue #6561: '\d' in a regex now matches only characters with Unicode category
+  'Nd' (Number, Decimal Digit).  Previously it also matched characters with
+  category 'No'.
+
+- Issue #1523: Remove deprecated overflow wrapping for struct.pack with an
+  integer format code ('bBhHiIlLqQ').  Packing an out-of-range integer now
+  consistently raises struct.error.
+
+- Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the
+  integer formats ('bBhHiIlLqQ').  In the following, '*' represents any of '=',
+  '<', '>'.
+
+    - Packing a float now always gives a Deprecation Warning.  Previously it
+      only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
+
+    - If x is not an int, long or float, then packing x will always result in
+      struct.error.  Previously an x with an __int__ method could be packed by
+      'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
+      __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
+      neither __int__ nor __long__, TypeError used to be raised (with a
+      confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
+      struct.error in other cases.
+
+  Note: as of Python 2.7 beta 1, the above is out of date.  In 2.7 beta 1, any
+  argument with an __int__ method can be packed, but use of this feature
+  triggers a DeprecationWarning.

 Tests
 -----
+
+- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
+  in the Lib/test directory, which might be read-only for the user running the
+  tests.
+
+- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
+  of an option with no handler.
+
+- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
+  fails.  Can be combined with -j.
+
+- Issue #7295: Do not use a hardcoded file name in test_tarfile.
+
+- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
+  primitives such as Lock, RLock, Condition, Event and Semaphore.
+
+- Issue #7222: Make thread "reaping" more reliable so that reference
+  leak-chasing test runs give sensible results.  The previous method of reaping
+  threads could return successfully while some Thread objects were still
+  referenced.  This also introduces a new private function: ``thread._count()``.
+
+- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
+  runs the risk of causing the worker thread to fail.
+
+- Issue #7055: test___all__ now greedily detects all modules which have an
+  __all__ attribute, rather than using a hardcoded and incomplete list.
+
+- Issue #7058: Added save/restore for things like sys.argv and cwd to
+  runtest_inner in regrtest, with warnings if the called test modifies them,
+  and a new section in the summary report at the end.
+
+- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
+
+- Issue #6806: test_platform failed under OS X 10.6.0 because ``sw_ver`` leaves
+  off the trailing 0 in the version number.
+
+- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
+  Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
+  the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
+  the tests if DISPLAY is defined but can't be used.
+
+- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
+  regression tests in parallel, shortening the total runtime.
+
+- Issue #5354: New test support function import_fresh_module() makes it easy to
+  import both normal and optimised versions of modules.  test_heapq and
+  test_warnings have been adjusted to use it, tests for other modules with both
+  C and Python implementations in the stdlib can be adjusted to use it over
+  time.
+
+- Fix test_warnings to no longer reset the warnings filter.
+
+- Fix test_logging to no longer reset the warnings filter.
+
+- Issue #5635: Fix running test_sys with tracing enabled.
+
+- regrtest no longer treats ImportError as equivalent to SkipTest.  Imports that
+  should cause a test to be skipped are now done using import_module from test
+  support, which does the conversion.
+
+- Issue #5083: New 'gui' resource for regrtest.

------------------
-
-- xrange() is now registered as a Sequence.
-
-- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
-  when hitting the recursion limit under certain circumstances.
-
-- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
-
-- Issue #4034: Fix weird attribute error messages of the traceback object. (As
-  a result traceback.__members__ no longer exists.)
-
-- Issue #5247: Improve error message when unknown format codes are

-  for ints and longs.
-
-- Issue #5013: Fixed a bug in FileHandler which occurred when the delay
-  parameter was set.
-
-- Issue 1242657: the __len__() and __length_hint__() calls in several tools
-  were suppressing all exceptions.  These include list(), filter(), map(),
-  zip(), and bytearray().
-
-- Issue #4935: The overflow checking code in the expandtabs() method common
-  to str, bytes and bytearray could be optimized away by the compiler, letting
-  the interpreter segfault instead of raising an error.
-
-- Issue #4915: Port sysmodule to Windows CE.
-
-- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
-  an existing .py counterpart, override the co_filename attributes of all
-  code objects if the original filename is obsolete (which can happen if the
-  file has been renamed, moved, or if it is accessed through different paths).
-  Patch by Ziga Seilnacht and Jean-Paul Calderone.
-
-- Issue #4075: Use OutputDebugStringW in Py_FatalError.
-
-- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

-  directory on POSIX systems.
-
-- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
-  systems.

-  print elapsed times, not only when some objects are uncollectable /
-  unreachable. Original patch by Neil Schemenauer.
-
-- Issue #4589: Fixed exception handling when the __exit__ function of a
-  context manager returns a value that cannot be converted to a bool.
-
-- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
-  method on file objects with closefd=False. The file descriptor is still
-  kept open but the file object behaves like a closed file. The ``FileIO``
-  object also got a new readonly attribute ``closefd``.
-
-- Issue #3689: The list reversed iterator now supports __length_hint__
-  instead of __len__.  Behavior now matches other reversed iterators.
-
-- Issue #4509: Various issues surrounding resize of bytearray objects to
-  which there are buffer exports.
-
-- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
-  short file names.

-  output compared to previous Python versions.
-
-- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop

-  overrun.
-
-- Issue #5292: Fixed mmap crash on its boundary access m[len(m)].
-
-- Issue #5282: Fixed mmap resize on 32bit windows and unix. When offset > 0,

-  Initial patch by Amaury Forgeot d'Arc.
-
-- Issue #4998: The memory saving effect of __slots__ had been lost on Fractions

-  function without argtypes (only occurs if HAVE_USABLE_WCHAR_T is false).
-
-- Issue #3321: _multiprocessing.Connection() doesn't check handle; added checks
-  for *nix machines for negative handles and large int handles. Without this

-
-- Issue #5008: When a file is opened in append mode with the new IO library,

-  opened with other applications.
-
-- Issue 4816: itertools.combinations() and itertools.product were raising

-  from inside a module loaded via a PEP 302 loader and attempting to
-  perform IO operations based on __file__). Original patch by
-  Alexander Belopolsky.
-
-- Issues #4082 and #4512: Add runpy support to zipimport in a manner that
-  allows backporting to maintenance branches. Original patch by
-  Alexander Belopolsky.

-What's New in Python 2.6.1
-==========================
-
-*Release date: 04-Dec-2008*
-
-Core and Builtins
------------------
-
-- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
-  interpreter to abort ("Fatal Python error: Could not reset the stack!")
-  instead of throwing a MemoryError.
-
-- Issue #4367: Python would segfault during compiling when the unicodedata
-  module couldn't be imported and \N escapes were present.
-
-- Issue #4348: Some bytearray methods returned that didn't cause any change to
-  the bytearray, returned the same bytearray instead of a copy.
-
-- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
-
-- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
-
-- Issue #4048: The parser module now correctly validates relative imports.
-
-- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
-  exec statement.
-
-- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
-  method does not return iterators for the 4th and 5th items.
-
-- Issue #4209: Enabling unicode_literals and the print_function in the same
-  __future__ import didn't work.
-
-- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
-  returned a path longer than MAX_PATH. (But It's doubtful this code path is
-  really executed because I cannot move to such directory on win2k)
-
-- Issue #4069: When set.remove(element) is used with a set element, the element
-  is temporarily replaced with an equivalent frozenset.  But the eventual
-  KeyError would always report the empty frozenset([]) as the missing key. Now
-  it correctly refers to the initial element.
-
-- Fixed C99 style comments in several files. Python is now C89 compatible
-  again.
-
-Library
--------
-
-- Issue #3741: DISTUTILS_USE_SDK set causes msvc9compiler.py to raise an
-  exception.
-
-- Issue #4363: The uuid.uuid1() and uuid.uuid4() functions now work even if
-  the ctypes module is not present.
-
-- Issue #4116: Resolve member name conflict in ScrolledCanvas.__init__.
-
-- Issue #3774: Fixed an error when create a Tkinter menu item without command
-  and then remove it.
-
-- Fixed a modulefinder crash on certain relative imports.
-
-- Issue #4150: Pdb's "up" command now works for generator frames in post-mortem
-  debugging.
-
-- Issue #4092: Return ArgInfo as promised in the documentation from
-  inspect.getargvalues.
-
-- Issue #3935: Properly support list subclasses in bisect's C implementation.
-
-- Issue #4014: Don't claim that Python has an Alpha release status, in addition
-  to claiming it is Mature.
-
