- utf-8 cache.
-
-Windows
--------
-
-- Issue #25715: Python 3.5.1 installer shows wrong upgrade path and incorrect

-
-
-What's New in Python 3.5.1 release candidate 1?
-===============================================
-
-Release date: 2015-11-22
-
-Core and Builtins
------------------
-
-- Issue #25630: Fix a possible segfault during argument parsing in functions
- that accept filesystem paths.
-
-- Issue #23564: Fixed a partially broken sanity check in the _posixsubprocess
- internals regarding how fds_to_pass were passed to the child. The bug had
- no actual impact as subprocess.py already avoided it.
-
-- Issue #25388: Fixed tokenizer crash when processing undecodable source code
- with a null byte.
-
-- Issue #25462: The hash of the key now is calculated only once in most
- operations in C implementation of OrderedDict.
-
-- Issue #22995: Default implementation of __reduce__ and __reduce_ex__ now
- rejects builtin types with not defined __new__.
-
-- Issue #25555: Fix parser and AST: fill lineno and col_offset of "arg" node
- when compiling AST from Python objects.
-
-- Issue #24802: Avoid buffer overreads when int(), float(), compile(), exec()
- and eval() are passed bytes-like objects. These objects are not
- necessarily terminated by a null byte, but the functions assumed they were.
-
-- Issue #24726: Fixed a crash and leaking NULL in repr() of OrderedDict that
- was mutated by direct calls of dict methods.
-
-- Issue #25449: Iterating OrderedDict with keys with unstable hash now raises
- KeyError in C implementations as well as in Python implementation.
-
-- Issue #25395: Fixed crash when highly nested OrderedDict structures were
- garbage collected.
-
-- Issue #25274: sys.setrecursionlimit() now raises a RecursionError if the new
- recursion limit is too low depending at the current recursion depth. Modify
- also the "lower-water mark" formula to make it monotonic. This mark is used
- to decide when the overflowed flag of the thread state is reset.
-
-- Issue #24402: Fix input() to prompt to the redirected stdout when
- sys.stdout.fileno() fails.
-
-- Issue #24806: Prevent builtin types that are not allowed to be subclassed from
- being subclassed through multiple inheritance.
-
-- Issue #24848: Fixed a number of bugs in UTF-7 decoding of misformed data.
-
-- Issue #25280: Import trace messages emitted in verbose (-v) mode are no
- longer formatted twice.
-
-- Issue #25003: On Solaris 11.3 or newer, os.urandom() now uses the
- getrandom() function instead of the getentropy() function. The getentropy()
- function is blocking to generate very good quality entropy, os.urandom()
- doesn't need such high-quality entropy.
-
-- Issue #25182: The stdprinter (used as sys.stderr before the io module is
- imported at startup) now uses the backslashreplace error handler.
-
-- Issue #25131: Make the line number and column offset of set/dict literals and
- comprehensions correspond to the opening brace.
-
-- Issue #25150: Hide the private _Py_atomic_xxx symbols from the public
- Python.h header to fix a compilation error with OpenMP. PyThreadState_GET()
- becomes an alias to PyThreadState_Get() to avoid ABI incompatibilies.
-
-Library
--------
-
-- Issue #25626: Change three zlib functions to accept sizes that fit in
- Py_ssize_t, but internally cap those sizes to UINT_MAX. This resolves a
- regression in 3.5 where GzipFile.read() failed to read chunks larger than 2
- or 4 GiB. The change affects the zlib.Decompress.decompress() max_length
- parameter, the zlib.decompress() bufsize parameter, and the
- zlib.Decompress.flush() length parameter.
-
-- Issue #25583: Avoid incorrect errors raised by os.makedirs(exist_ok=True)
- when the OS gives priority to errors such as EACCES over EEXIST.
-
-- Issue #25593: Change semantics of EventLoop.stop() in asyncio.
-
-- Issue #6973: When we know a subprocess.Popen process has died, do
- not allow the send_signal(), terminate(), or kill() methods to do

-C API
------
-
-- Issue #14203: Remove obsolete support for view==NULL in PyBuffer_FillInfo(),
- bytearray_getbuffer(), bytesiobuf_getbuffer() and array_buffer_getbuf().
- All functions now raise BufferError in that case.
-
-- Issue #22445: PyBuffer_IsContiguous() now implements precise contiguity
- tests, compatible with NumPy's NPY_RELAXED_STRIDES_CHECKING compilation
- flag. Previously the function reported false negatives for corner cases.
-
-- Issue #22079: PyType_Ready() now checks that statically allocated type has
- no dynamically allocated bases.
-
-- Issue #22453: Removed non-documented macro PyObject_REPR().

- these functions.
-
-- Issue #21233: Add new C functions: PyMem_RawCalloc(), PyMem_Calloc(),
- PyObject_Calloc(), _PyObject_GC_Calloc(). bytes(int) is now using
- ``calloc()`` instead of ``malloc()`` for large objects which is faster and
- use less memory.
-
-- Issue #20942: PyImport_ImportFrozenModuleObject() no longer sets __file__ to
- match what importlib does; this affects _frozen_importlib as well as any
- module loaded using imp.init_frozen().
-
-Documentation
--------------

- the Python Packaging Authority tools. Existing guides have been retained
- as legacy links from the distutils docs, as they still contain some
- required reference material for tool developers that isn't recorded
- anywhere else.
-
-- Issue #19697: Document cases where __main__.__spec__ is None.
-

-
-- asyncio: Refactoring and fixes: BaseEventLoop.sock_connect() raises an
- error if the address is not resolved; use __slots__ in Handle and
- TimerHandle; as_completed() and wait() raise TypeError if the passed
- list of Futures is a single Future; call_soon() and other 'call_*()'
- functions raise TypeError if the passed callback is a coroutine

-===============================================
-
-Release date: 2014-02-10
-
-Core and Builtins
------------------
-
-- Issue #19255: The builtins module is restored to initial value before
- cleaning other modules. The sys and builtins modules are cleaned last.
-
-- Issue #20588: Make Python-ast.c C89 compliant.
-
-- Issue #20437: Fixed 22 potential bugs when deleting object 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).
-
-Library
--------
-
-- Issue #20530: The signatures for slot builtins have been updated
- to reflect the fact that they only accept positional-only arguments.

-- Issue #20517: Functions in the os module that accept two filenames
- now register both filenames in the exception on failure.
-
-- Issue #20563: The ipaddress module API is now considered stable.
-
-- Issue #14983: email.generator now always adds a line end after each MIME
- boundary marker, instead of doing so only when there is an epilogue. This
- fixes an RFC compliance bug and solves an issue with signed MIME parts.
-
-- Issue #20540: Fix a performance regression (vs. Python 3.2) when layering
- 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.
-
-- Issue #20515: Fix NULL pointer dereference introduced by issue #20368.
-

- settings in the default pip configuration file.
-
-- Issue #20426: When passing the re.DEBUG flag, re.compile() displays the
- debug output every time it is called, regardless of the compilation cache.
-
-- Issue #20368: The null character now correctly passed from Tcl to Python.
- 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.
-
-- Issue #20288: fix handling of invalid numeric charrefs in HTMLParser.
-
-- Issue #20424: Python implementation of io.StringIO now supports lone surrogates.
-
-- Issue #20308: inspect.signature now works on classes without user-defined
- __init__ or __new__ methods.

-- Issue #20372: inspect.getfile (and a bunch of other inspect functions that
- use it) doesn't crash with unexpected AttributeError on classes defined in C
- without __module__.

- functools.partialmethods.
-
-- Issue #19456: ntpath.join() now joins relative paths correctly when a drive

-
-- Issue #20105: the codec exception chaining now correctly sets the
- traceback of the original exception as its __traceback__ attribute.
-
-- Issue #17481: inspect.getfullargspec() now uses inspect.signature() API.
-
-- Issue #15304: concurrent.futures.wait() can block forever even if

-
-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: 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.
-
-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.

-- 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.

- input; reworded docs to clarify that an integer type should define both __int__
- and __index__.
-

- 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

- child processes when necessary, allowing it to correctly handle scripts
- without suffixes and submodules that use explicit relative imports or
- 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 object destructors. So "unclosed file" resource
- warnings are now correctly 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

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

-- Issue #18972: Modernize email examples and use the argparse module in them.
-
-Build
------
-
-- Issue #19130: Correct PCbuild/readme.txt, Python 3.3 and 3.4 require VS 2010.
-
-- Issue #15663: Update OS X 10.6+ installer to use Tcl/Tk 8.5.15.
-
-- 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.
