-IDLE
-----
-
-- Issue 15348: Stop the debugger engine (normally in a user process)
- before closing the debugger window (running in the IDLE process).
- This prevents the RuntimeErrors that were being caught and ignored.
-
-- Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
- debugger is active (15347); b) closing the debugger with the [X] button
- (15348); and c) activating the debugger when already active (24455).
- The patch by Mark Roseman does this by making two changes.
- 1. Suspend and resume the gui.interaction method with the tcl vwait
- mechanism intended for this purpose (instead of root.mainloop & .quit).
- 2. In gui.run, allow any existing interaction to terminate first.
-

- 'Save as New Custom Theme' button and enter a new name,
- such as 'Custom Dark'. The custom theme will work with any IDLE
- release, and can be modified.

-
-- Issue #20437: Fixed 22 potential bugs when deleting objects references.
-
-- Issue #20500: Displaying an exception at interpreter shutdown no longer
- risks triggering an assertion failure in PyObject_Str.
-
-- Issue #20538: UTF-7 incremental decoder produced inconsistent string when
- input was truncated in BASE64 section.
-
-- Issue #20404: io.TextIOWrapper (and hence the open() builtin) now uses the
- internal codec marking system added for issue #19619 to throw LookupError
- for known non-text encodings at stream construction time. The existing
- output type checks remain in place to deal with unmarked third party
- codecs.
-
-- Issue #17162: Add PyType_GetSlot.
-
-- Issue #20162: Fix an alignment issue in the siphash24() hash function which
- caused a crash on PowerPC 64-bit (ppc64).

- a multiprocessing Connection over a TCP socket. For small payloads, Nagle's
- algorithm would introduce idle delays before the entire transmission of a
- message.
-
-- Issue #16983: the new email header parsing code will now decode encoded words
- that are (incorrectly) surrounded by quotes, and register a defect.
-
-- Issue #19772: email.generator no longer mutates the message object when
- doing a down-transform from 8bit to 7bit CTEs.
-
-- Issue #20536: the statistics module now correctly handle Decimal instances
- with positive exponents
-
-- Issue #18805: the netmask/hostmask parsing in ipaddress now more reliably
- filters out illegal values and correctly allows any valid prefix length.
-
-- Issue #20481: For at least Python 3.4, the statistics module will require
- that all inputs for a single operation be of a single consistent type, or
- else a mixed of ints and a single other consistent type. This avoids
- some interoperability issues that arose with the previous approach of
- coercing to a suitable common type.
-
-- Issue #20478: the statistics module now treats collections.Counter inputs
- like any other iterable.
-
-- Issue #17369: get_filename was raising an exception if the filename
- parameter's RFC2231 encoding was broken in certain ways. This was
- a regression relative to python2.
-
-- Issue #20013: Some imap servers disconnect if the current mailbox is
- deleted, and imaplib did not handle that case gracefully. Now it
- handles the 'bye' correctly.
-
-- Issue #20531: Revert 3.4 version of fix for #19063, and apply the 3.3
- version. That is, do *not* raise an error if unicode is passed to
- email.message.Message.set_payload.
-
-- Issue #20476: If a non-compat32 policy is used with any of the email parsers,
- EmailMessage is now used as the factory class. The factory class should
- really come from the policy; that will get fixed in 3.5.
-
-- Issue #19920: TarFile.list() no longer fails when outputs a listing
- containing non-encodable characters. Based on patch by Vajrasky Kok.

- Improved error handling in variables-related commands.
-
-- Issue #20435: Fix _pyio.StringIO.getvalue() to take into account newline
- translation settings.
-
-- tracemalloc: Fix slicing traces and fix slicing a traceback.
-
-- Issue #20354: Fix an alignment issue in the tracemalloc module on 64-bit
- platforms. Bug seen on 64-bit Linux when using "make profile-opt".

-- Issue #17159: inspect.signature now accepts duck types of functions,
- which adds support for Cython functions. Initial patch by Stefan Behnel.
-
-- Issue #18801: Fix inspect.classify_class_attrs to correctly classify
- object.__new__ and object.__init__.
-
-- Fixed cmath.isinf's name in its argument parsing code.
-
-- Issue #20311, #20452: poll and epoll now round the timeout away from zero,
- instead of rounding towards zero, in select and selectors modules:
- select.epoll.poll(), selectors.PollSelector.poll() and
- selectors.EpollSelector.poll(). For example, a timeout of one microsecond
- (1e-6) is now rounded to one millisecondi (1e-3), instead of being rounded to
- zero. However, the granularity property and asyncio's resolution feature
- were removed again.
-
-- asyncio: Some refactoring; various fixes; add write flow control to
- unix pipes; Future.set_exception() instantiates the exception
- argument if it is a class; improved proactor pipe transport; support
- wait_for(f, None); don't log broken/disconnected pipes; use
- ValueError instead of assert for forbidden subprocess_{shell,exec}
- arguments; added a convenience API for subprocess management; added
- StreamReader.at_eof(); properly handle duplicate coroutines/futures
- in gather(), wait(), as_completed(); use a bytearray for buffering
- in StreamReader; and more.

-
-Tools/Demos
------------
-
-- Issue #20530: Argument Clinic's signature format has been revised again.
- The new syntax is highly human readable while still preventing false
- positives. The syntax also extends Python syntax to denote "self" and
- positional-only parameters, allowing inspect.Signature objects to be
- totally accurate for all supported builtins in Python 3.4.
-
-- 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: 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.
-
-C-API
------
-
-- Issue #20517: Added new functions allowing OSError exceptions to reference
- two filenames instead of one: PyErr_SetFromErrnoWithFilenameObjects() and
- PyErr_SetExcFromWindowsErrWithFilenameObjects().
-
-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.

- 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

- otherwise rely on parent modules being correctly imported prior to
- execution.
-
-- Issue #19921: When Path.mkdir() is called with parents=True, any missing
- parent is created with the default permissions, ignoring the mode argument
- (mimicking the POSIX "mkdir -p" command).
-
-- Issue #19887: Improve the Path.resolve() algorithm to support certain
- symlink chains.
-
-- Issue #19912: Fixed numerous bugs in ntpath.splitunc().

-
-- Issue #19063: if a Charset's body_encoding was set to None, the email

-
-- Issue #19944: Fix importlib.find_spec() so it imports parents as needed
- and move the function to importlib.util.
-

- reference cycles between frames and the _Outcome instance.
-
-- Issue #17429: platform.linux_distribution() now decodes files from the UTF-8
- encoding with the surrogateescape error handler, instead of decoding from the
- locale encoding in strict mode. It fixes the function on Fedora 19 which is
- probably the first major distribution release with a non-ASCII name. Patch
- written by Toshio Kuratomi.
-
-- Issue #19343: Expose FreeBSD-specific APIs in resource module. Original
- patch by Koobs.
-
-- Issue #19929: Call os.read with 32768 within subprocess.Popen.communicate

-What's New in Python 3.4.0 Beta 1?
-==================================
-
-Release date: 2013-11-24
-
-Core and Builtins
------------------
-
-- Use the repr of a module name in more places in import, especially
- exceptions.
-
-- Issue #19619: str.encode, bytes.decode and bytearray.decode now use an
- internal API to throw LookupError for known non-text encodings, rather
- than attempting the encoding or decoding operation and then throwing a
- TypeError for an unexpected output type. (The latter mechanism remains
- in place for third party non-text encodings)
-
-- Issue #19183: Implement PEP 456 'secure and interchangeable hash algorithm'.
- Python now uses SipHash24 on all major platforms.
-
-- Issue #12892: The utf-16* and utf-32* encoders no longer allow surrogate code
- points (U+D800-U+DFFF) to be encoded. The utf-32* decoders no longer decode
- byte sequences that correspond to surrogate code points. The surrogatepass
- error handler now works with the utf-16* and utf-32* codecs. Based on
- patches by Victor Stinner and Kang-Hao (Kenny) Lu.
-
-- Issue #17806: Added keyword-argument support for "tabsize" to
- str/bytes.expandtabs().
-
-- Issue #17828: Output type errors in str.encode(), bytes.decode() and
- bytearray.decode() now direct users to codecs.encode() or codecs.decode()
- as appropriate.
-
-- Issue #17828: The interpreter now attempts to chain errors that occur in
- codec processing with a replacement exception of the same type that
- includes the codec name in the error message. It ensures it only does this
- when the creation of the replacement exception won't lose any information.
-
-- Issue #19466: Clear the frames of daemon threads earlier during the
- Python shutdown to call objects destructors. So "unclosed file" resource
- warnings are now corretly emitted for daemon threads.
-
-- Issue #19514: Deduplicate some _Py_IDENTIFIER declarations.
- Patch by Andrei Dorian Duma.
-
-- Issue #17936: Fix O(n**2) behaviour when adding or removing many subclasses
- of a given type.
-
-- Issue #19428: zipimport now handles errors when reading truncated or invalid
- ZIP archive.
-
-- Issue #18408: Add a new PyFrame_FastToLocalsWithError() function to handle
- exceptions when merging fast locals into f_locals of a frame.
- PyEval_GetLocals() now raises an exception and return NULL on failure.
-

- does affect -m/runpy). It also allows FileFinder to be more consistent by not
- having an edge case.

-
-- Issue #14499: Fix several problems with OS X universal build support:
- 1. ppc arch detection for extension module builds broke with Xcode 5
- 2. ppc arch detection in configure did not work on OS X 10.4
- 3. -sysroot and -arch flags were unnecessarily duplicated
- 4. there was no obvious way to configure an intel-32 only build.
-
-- Issue #19019: Change the OS X installer build script to use CFLAGS instead
- of OPT for special build options. By setting OPT, some compiler-specific
- options like -fwrapv were overridden and thus not used, which could result
- in broken interpreters when building with clang.

-What's New in Python 3.3.0 Release Candidate 2?
-===============================================
-
-*Release date: 09-Sep-2012*
-
-Core and Builtins

- method.
-
-- Issue #15785: Modify `window.get_wch()` API of the curses module: return a

- returning an integer. So it is now possible to distinguish special keys like
- keypad keys.
-
-- Issue #14223: Fix `window.addch()` of the curses module for special characters
- like curses.ACS_HLINE: the Python function addch(int) and addch(bytes) is now
- calling the C function waddch()/mvwaddch() (as it was done in Python 3.2),
- instead of wadd_wch()/mvwadd_wch(). The Python function addch(str) is still
- calling the C function wadd_wch()/mvwadd_wch() if the Python curses is linked
- to libncursesw.

- interpreter would sometimes invoke the wrong metaclass when building a new
- class object. These cases now behave correctly. Patch by Daniel Urban.
-

- 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 #10968: Remove indirection in threading. The public names (Event,
- Condition, etc.) used to be factory functions returning instances of hidden

-
-- 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. Also, implement the same handling in packaging.

+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
