| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #23722: The __class__ cell used by zero-argument super() is now |
| initialized from type.__new__ rather than __build_class__, so class methods |

| - Issue #27948: In f-strings, only allow backslashes inside the braces |
| (where the expressions are). This is a breaking change from the 3.6 |
| alpha releases, where backslashes are allowed anywhere in an |
| f-string. Also, require that expressions inside f-strings be |
| enclosed within literal braces, and not escapes like |
| f'\x7b"hi"\x7d'. |

| compiled without ``long long`` for years, so this is basically a formality. |
| |
| - Issue #27355: Removed support for Windows CE. It was never finished, |
| and Windows CE is no longer a relevant platform for Python. |
| |
| - Implement PEP 523. |
| |
| - Issue #27870: A left shift of zero by a large integer no longer attempts |
| to allocate large amounts of memory. |
| |
| - Issue #25402: In int-to-decimal-string conversion, improve the estimate |
| of the intermediate memory required, and remove an unnecessarily strict |
| overflow check. Patch by Serhiy Storchaka. |
| |

| unreliable ldexp implementations. |
| |
| - Issue #24254: Make class definition namespace ordered by default. |
| |

| of non-module types returned from ``Py_create_mod``. Patch by Xiang Zhang. |

| |
| - Issue #26249: Memory functions of the :c:func:`PyMem_Malloc` domain |
| (:c:data:`PYMEM_DOMAIN_MEM`) now use the :ref:`pymalloc allocator <pymalloc>` |
| rather than system :c:func:`malloc`. Applications calling |

| ``PYTHONMALLOC=debug`` environment variable to validate the usage of memory |
| allocators in your application. |
| |
| - Issue #26802: Optimize function calls only using unpacking like |
| ``func(*tuple)`` (no other positional argument, no keyword): avoid copying |

| memory allocators when Python is configured without pymalloc. |
| |
| - Issue #26464: Fix str.translate() when string is ASCII and first replacements |
| removes character, but next replacement uses a non-ASCII character or a |
| string longer than 1 character. Regression introduced in Python 3.5.0. |
| |
| - Issue #22836: Ensure exception reports from PyErr_Display() and |
| PyErr_WriteUnraisable() are sensible even when formatting them produces |
| secondary errors. This affects the reports produced by |

| |
| - Issue #26302: Correct behavior to reject comma as a legal character for |
| cookie names. |
| |

| - Issue #26146: Add a new kind of AST node: ``ast.Constant``. It can be used |
| by external AST optimizers, but the compiler does not emit directly such |
| node. |
| |
| - Issue #23601: Sped-up allocation of dict key objects by using Python's |
| small object allocator. (Contributed by Julian Taylor.) |
| |
| - Issue #18018: Import raises ImportError instead of SystemError if a relative |
| import is attempted without a known parent package. |
| |
| - Issue #25843: When compiling code, don't merge constants if they are equal |
| but have a different types. For example, ``f1, f2 = lambda: 1, lambda: 1.0`` |
| is now correctly compiled to two different functions: ``f1()`` returns ``1`` |
| (``int``) and ``f2()`` returns ``1.0`` (``float``), even if ``1`` and ``1.0`` |
| are equal. |
| |
| - Issue #26107: The format of the ``co_lnotab`` attribute of code objects |
| changes to support negative line number delta. |
| |

| This new function must be used instead of accessing directly the |
| _PyThreadState_Current variable. The variable is no more exposed since |
| Python 3.5.1 to hide the exact implementation of atomic C types, to avoid |
| compiler issues. |

| subclasses of list or dict and haven't implemented any pickle-related |
| methods (__reduce__, __reduce_ex__, __getnewargs__, __getnewargs_ex__, |
| or __getstate__), can no longer be pickled. Including memoryview. |
| |

| macro Py_SETREF. |
| |
| - Issue #25766: Special method __bytes__() now works in str subclasses. |

| 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. |

| rejects builtin types with not defined __new__. |
| |
| - 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 #25555: Fix parser and AST: fill lineno and col_offset of "arg" node |
| when compiling AST from Python objects. |
| |

| 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 #25349: Optimize bytes % args using the new private _PyBytesWriter API. |
| Formatting is now up to 2 times faster. |

| written by Serhiy Storchaka. |
| |
| - 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 #9232: Modify Python's grammar to allow trailing commas in the |
| argument list of a function declaration. For example, "def f(\*, a = |
| 3,): pass" is now legal. Patch from Mark Dickinson. |
| |
| - Issue #24965: Implement PEP 498 "Literal String Interpolation". This |
| allows you to embed expressions inside f-strings, which are |

| is now up to 2.5 times faster. |
| |
| - Issue #25902: Fixed various refcount issues in ElementTree iteration. |
| |
| - Issue #22227: The TarFile iterator is reimplemented using generator. |

| anonymous temporary files from working in special cases. |
| |
| - Issue #24903: Fix regression in number of arguments compileall accepts when |
| '-d' is specified. The check on the number of arguments has been dropped |
| completely as it never worked correctly anyway. |

| |
| - Issue #14285: When executing a package with the "python -m package" option, |

| - Issue #19771: Also in runpy and the "-m" option, omit the irrelevant |
| message ". . . is a package and cannot be directly executed" if the package |
| could not even be initialized (e.g. due to a bad ``*.pyc`` file). |
| |

| entries. Patch by Dingyuan Wang. |
| |
| - 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 |
| anything as they could potentially signal a different process. |
| |
| - Issue #23883: Added missing APIs to __all__ to match the documented APIs |
| for the following modules: calendar, csv, enum, fileinput, ftplib, logging, |

| attribute. Also complete names of attributes such as properties and slots |
| which are listed by dir() but not yet created on an instance. |

| and reuseaddr socket options to be set prior to binding the socket. |
| Mirroring the existing asyncio create_server method the reuseaddr option |

| IDLE |
| ---- |
| |
| - Issue #20640: Add tests for idlelib.configHelpSourceEdit. |
| Patch by Saimadhav Heblikar. |
| |
| - In the 'IDLE-console differences' section of the IDLE doc, clarify |
| how running with IDLE affects sys.modules and the standard streams. |
| |
| - Issue #25507: fix incorrect change in IOBinding that prevented printing. |
| Augment IOBinding htest to include all major IOBinding functions. |
| |
| - Issue #25905: Revert unwanted conversion of ' to ’ RIGHT SINGLE QUOTATION |
| MARK in README.txt and open this and NEWS.txt with 'ascii'. |
| Re-encode CREDITS.txt to utf-8 and open it with 'utf-8'. |
| |
| - 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. |
| |
| - Change 'The program' to 'Your program' in an IDLE 'kill program?' message |
| to make it clearer that the program referred to is the currently running |
| user program, not IDLE itself. |

| Patch by Mark Roseman. |
| |

| address the compatibility problem introduced by the addition of IDLE Dark. |
| Consistently use the revised idleConf.CurrentTheme everywhere in idlelib. |
| |
| - Issue #24782: Extension configuration is now a tab in the IDLE Preferences |
| dialog rather than a separate dialog. The former tabs are now a sorted |
| list. Patch by Mark Roseman. |
| |
| - Issue #22726: Re-activate the config dialog help button with some content |
| about the other buttons and the new IDLE Dark theme. |
| |
| - Issue #24820: IDLE now has an 'IDLE Dark' built-in text color theme. |
| It is more or less IDLE Classic inverted, with a cobalt blue background. |
| Strings, comments, keywords, ... are still green, red, orange, ... . |
| To use it with IDLEs released before November 2015, hit the |
| '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 #25224: README.txt is now an idlelib index for IDLE developers and |
| curious users. The previous user content is now in the IDLE doc chapter. |
| 'IDLE' now means 'Integrated Development and Learning Environment'. |
| |
| - Issue #24820: Users can now set breakpoint colors in |
| Settings -> Custom Highlighting. Original patch by Mark Roseman. |
| |
| - Issue #24972: Inactive selection background now matches active selection |
| background, as configured by users, on all systems. Found items are now |
| always highlighted on Windows. Initial patch by Mark Roseman. |
| |
| - Issue #24570: Idle: make calltip and completion boxes appear on Macs |
| affected by a tk regression. Initial patch by Mark Roseman. |

| now work on Mac Aqua. Patch by Mark Roseman. |
| |
| - Issue #24801: Make right-click for context menu work on Mac Aqua. |
| Patch by Mark Roseman. |
| |
| - Issue #25173: Associate tkinter messageboxes with a specific widget. |
| For Mac OSX, make them a 'sheet'. Patch by Mark Roseman. |
| |
| - Issue #25198: Enhance the initial html viewer now used for Idle Help. |
| * Properly indent fixed-pitch text (patch by Mark Roseman). |
| * Give code snippet a very Sphinx-like light blueish-gray background. |
| * Re-use initial width and height set by users for shell and editor. |
| * When the Table of Contents (TOC) menu is used, put the section header |
| at the top of the screen. |
| |
| - Issue #25225: Condense and rewrite Idle doc section on text colors. |
| |
| - Issue #21995: Explain some differences between IDLE and console Python. |
| |
| - Issue #22820: Explain need for *print* when running file from Idle editor. |
| |
| - Issue #25224: Doc: augment Idle feature list and no-subprocess section. |
| |
| - Issue #25219: Update doc for Idle command line options. |
| Some were missing and notes were not correct. |
| |
| - Issue #24861: Most of idlelib is private and subject to change. |
| Use idleib.idle.* to start Idle. See idlelib.__init__.__doc__. |
| |
| - Issue #25199: Idle: add synchronization comments for future maintainers. |
| |
| - Issue #16893: Replace help.txt with help.html for Idle doc display. |
| The new idlelib/help.html is rstripped Doc/build/html/library/idle.html. |
| It looks better than help.txt and will better document Idle as released. |
| The tkinter html viewer that works for this file was written by Rose Roseman. |
| The now unused EditorWindow.HelpDialog class and helt.txt file are deprecated. |
| |
| - Issue #24199: Deprecate unused idlelib.idlever with possible removal in 3.6. |
| |
| - Issue #24790: Remove extraneous code (which also create 2 & 3 conflicts). |
| |

| avoids relying on svn.python.org, which recently changed root certificate. |
| |
| - Issue #25616: Tests for OrderedDict are extracted from test_collections |
| into separate file test_ordered_dict. |
| |
| - Issue #25449: Added tests for OrderedDict subclasses. |
| |

| - Issue #21668: Link audioop, _datetime, _ctypes_test modules to libm, |
| except on Mac OS X. Patch written by Chi Hsuan Yen. |
| |

| enable link time optimizations at build time during a make profile-opt. |
| Some compilers and toolchains are known to not produce stable code when |
| using LTO, be sure to test things thoroughly before relying on it. |
| It can provide a few % speed up over profile-opt alone. |
| |
| - Issue #26624: Adds validation of ucrtbase[d].dll version with warning |
| for old versions. |

| |
| 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 |
| anything as they could potentially signal a different process. |
| |
| - Issue #25590: In the Readline completer, only call getattr() once per |
| attribute. |
| |
| - Issue #25498: Fix a crash when garbage-collecting ctypes objects created |

| at the end if the FileInput was opened with binary mode. |
| Patch by Ryosuke Ito. |
| |
| - Issue #25503: Fixed inspect.getdoc() for inherited docstrings of properties. |
| Original patch by John Mark Vandenberg. |
| |
| - Issue #25515: Always use os.urandom as a source of randomness in uuid.uuid4. |
| |
| - Issue #21827: Fixed textwrap.dedent() for the case when largest common |
| whitespace is a substring of smallest leading whitespace. |
| Based on patch by Robert Li. |
| |

| |
| - Issue #25441: asyncio: Raise error from drain() when socket is closed. |
| |
| - Issue #25410: Cleaned up and fixed minor bugs in C implementation of |
| OrderedDict. |
| |

| the email package. Thanks to user simon04 for the patch. |
| |
| - Issue #25407: Remove mentions of the formatter module being removed in |
| Python 3.6. |
| |
| - Issue #25406: Fixed a bug in C implementation of OrderedDict.move_to_end() |
| that caused segmentation fault or hang in iterating after moving several |
| items to the start of ordered dict. |
| |

| decode_data and enable_SMTPUTF8 are set to true. |
| |
| - Issue #25316: distutils raises OSError instead of DistutilsPlatformError |
| when MSVC is not installed. |
| |
| - Issue #25380: Fixed protocol for the STACK_GLOBAL opcode in |
| pickletools.opcodes. |
| |
| - Issue #23972: Updates asyncio datagram create method allowing reuseport |
| and reuseaddr socket options to be set prior to binding the socket. |
| Mirroring the existing asyncio create_server method the reuseaddr option |
| for datagram sockets defaults to True if the O/S is 'posix' (except if the |
| platform is Cygwin). Patch by Chris Laws. |
| |
| - Issue #25304: Add asyncio.run_coroutine_threadsafe(). This lets you |
| submit a coroutine to a loop from another thread, returning a |
| concurrent.futures.Future. By Vincent Michel. |
| |
| - Issue #25232: Fix CGIRequestHandler to split the query from the URL at the |
| first question mark (?) rather than the last. Patch from Xiang Zhang. |
| |
| - Issue #24657: Prevent CGIRequestHandler from collapsing slashes in the |
| query part of the URL as if it were a path. Patch from Xiang Zhang. |

| |
| - Issue #22609: Constructor of collections.UserDict now accepts the self keyword |
| argument. |
| |
| - Issue #25111: Fixed comparison of traceback.FrameSummary. |
| |
| - Issue #25262: Added support for BINBYTES8 opcode in Python implementation of |
| unpickler. Highest 32 bits of 64-bit size for BINUNICODE8 and BINBYTES8 |
| opcodes no longer silently ignored on 32-bit platforms in C implementation. |
| |
| - Issue #25034: Fix string.Formatter problem with auto-numbering and |

| |
| - Issue #25203: Failed readline.set_completer_delims() no longer left the |
| module in inconsistent state. |
| |
| - Issue #23600: Default implementation of tzinfo.fromutc() was returning |
| wrong results in some cases. |
| |
| - Issue #23329: Allow the ssl module to be built with older versions of |
| LibreSSL. |
| |
| - Prevent overflow in _Unpickler_Read. |
| |
| - Issue #25047: The XML encoding declaration written by Element Tree now |
| respects the letter case given by the user. This restores the ability to |
| write encoding names in uppercase like "UTF-8", which worked in Python 2. |
| |
| - Issue #25135: Make deque_clear() safer by emptying the deque before clearing. |
| This helps avoid possible reentrancy issues. |
| |
| - Issue #19143: platform module now reads Windows version from kernel32.dll to |
| avoid compatibility shims. |
| |
| - Issue #25092: Fix datetime.strftime() failure when errno was already set to |
| EINVAL. |
| |
| - Issue #23517: Fix rounding in fromtimestamp() and utcfromtimestamp() methods |
| of datetime.datetime: microseconds are now rounded to nearest with ties |
| going to nearest even integer (ROUND_HALF_EVEN), instead of being rounding |
| towards minus infinity (ROUND_FLOOR). It's important that these methods use |
| the same rounding mode than datetime.timedelta to keep the property: |
| (datetime(1970,1,1) + timedelta(seconds=t)) == datetime.utcfromtimestamp(t). |
| It also the rounding mode used by round(float) for example. |
| |
| - Issue #25155: Fix datetime.datetime.now() and datetime.datetime.utcnow() on |
| Windows to support date after year 2038. It was a regression introduced in |
| Python 3.5.0. |
| |
| - Issue #25108: Omitted internal frames in traceback functions print_stack(), |
| format_stack(), and extract_stack() called without arguments. |
| |
| - Issue #25118: Fix a regression of Python 3.5.0 in os.waitpid() on Windows. |
| |
| - Issue #24684: socket.socket.getaddrinfo() now calls |
| PyUnicode_AsEncodedString() instead of calling the encode() method of the |
| host, to handle correctly custom string with an encode() method which doesn't |
| return a byte string. The encoder of the IDNA codec is now called directly |
| instead of calling the encode() method of the string. |
| |
| - Issue #25060: Correctly compute stack usage of the BUILD_MAP opcode. |
| |
| - Issue #24857: Comparing call_args to a long sequence now correctly returns a |
| boolean result instead of raising an exception. Patch by A Kaptur. |
| |
| - Issue #23144: Make sure that HTMLParser.feed() returns all the data, even |
| when convert_charrefs is True. |
| |

| in an infinite loop. Patch by Xavier de Gaye. |
| |
| - Issue #24891: Fix a race condition at Python startup if the file descriptor |
| of stdin (0), stdout (1) or stderr (2) is closed while Python is creating |
| sys.stdin, sys.stdout and sys.stderr objects. These attributes are now set |
| to None if the creation of the object failed, instead of raising an OSError |
| exception. Initial patch written by Marco Paolini. |
| |
| - Issue #24992: Fix error handling and a race condition (related to garbage |
| collection) in collections.OrderedDict constructor. |
| |
| - Issue #24881: Fixed setting binary mode in Python implementation of FileIO |

| - Issue #25569: Fix memory leak in SSLSocket.getpeercert(). |
| |
| - Issue #25471: Sockets returned from accept() shouldn't appear to be |
| nonblocking. |
| |
| - Issue #25319: When threading.Event is reinitialized, the underlying condition |
| should use a regular lock rather than a recursive lock. |
| |
| - Issue #21112: Fix regression in unittest.expectedFailure on subclasses. |
| Patch from Berker Peksag. |

| |
| 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. |
| |
| - Change 'The program' to 'Your program' in an IDLE 'kill program?' message |
| to make it clearer that the program referred to is the currently running |
| user program, not IDLE itself. |

| Patch by Mark Roseman. |
| |

| address the compatibility problem introduced by the addition of IDLE Dark. |
| Consistently use the revised idleConf.CurrentTheme everywhere in idlelib. |
| |
| - Issue #24782: Extension configuration is now a tab in the IDLE Preferences |
| dialog rather than a separate dialog. The former tabs are now a sorted |
| list. Patch by Mark Roseman. |
| |
| - Issue #22726: Re-activate the config dialog help button with some content |
| about the other buttons and the new IDLE Dark theme. |
| |
| - Issue #24820: IDLE now has an 'IDLE Dark' built-in text color theme. |
| It is more or less IDLE Classic inverted, with a cobalt blue background. |
| Strings, comments, keywords, ... are still green, red, orange, ... . |
| To use it with IDLEs released before November 2015, hit the |
| '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 #25224: README.txt is now an idlelib index for IDLE developers and |
| curious users. The previous user content is now in the IDLE doc chapter. |
| 'IDLE' now means 'Integrated Development and Learning Environment'. |
| |
| - Issue #24820: Users can now set breakpoint colors in |
| Settings -> Custom Highlighting. Original patch by Mark Roseman. |
| |
| - Issue #24972: Inactive selection background now matches active selection |
| background, as configured by users, on all systems. Found items are now |
| always highlighted on Windows. Initial patch by Mark Roseman. |
| |
| - Issue #24570: Idle: make calltip and completion boxes appear on Macs |
| affected by a tk regression. Initial patch by Mark Roseman. |
| |
| - Issue #24988: Idle ScrolledList context menus (used in debugger) |
| now work on Mac Aqua. Patch by Mark Roseman. |
| |
| - Issue #24801: Make right-click for context menu work on Mac Aqua. |
| Patch by Mark Roseman. |
| |
| - Issue #25173: Associate tkinter messageboxes with a specific widget. |
| For Mac OSX, make them a 'sheet'. Patch by Mark Roseman. |
| |
| - Issue #25198: Enhance the initial html viewer now used for Idle Help. |
| * Properly indent fixed-pitch text (patch by Mark Roseman). |
| * Give code snippet a very Sphinx-like light blueish-gray background. |
| * Re-use initial width and height set by users for shell and editor. |
| * When the Table of Contents (TOC) menu is used, put the section header |
| at the top of the screen. |
| |
| - Issue #25225: Condense and rewrite Idle doc section on text colors. |
| |
| - Issue #21995: Explain some differences between IDLE and console Python. |
| |
| - Issue #22820: Explain need for *print* when running file from Idle editor. |
| |
| - Issue #25224: Doc: augment Idle feature list and no-subprocess section. |
| |
| - Issue #25219: Update doc for Idle command line options. |
| Some were missing and notes were not correct. |
| |
| - Issue #24861: Most of idlelib is private and subject to change. |
| Use idleib.idle.* to start Idle. See idlelib.__init__.__doc__. |
| |
| - Issue #25199: Idle: add synchronization comments for future maintainers. |
| |
| - Issue #16893: Replace help.txt with help.html for Idle doc display. |
| The new idlelib/help.html is rstripped Doc/build/html/library/idle.html. |
| It looks better than help.txt and will better document Idle as released. |
| The tkinter html viewer that works for this file was written by Mark Roseman. |
| The now unused EditorWindow.HelpDialog class and helt.txt file are deprecated. |
| |
| - Issue #24199: Deprecate unused idlelib.idlever with possible removal in 3.6. |
| |
| - Issue #24790: Remove extraneous code (which also create 2 & 3 conflicts). |
| |
| Documentation |
| ------------- |
| |
| - Issue #12067: Rewrite Comparisons section in the Expressions chapter of the |
| language reference. Some of the details of comparing mixed types were |

| than the Expressions chapter. Added details of comparing range() objects, |
| and default behaviour and consistency suggestions for user-defined classes. |

| |
| - Issue #21859: Added Python implementation of io.FileIO. |

| |
| - Issue #23618: :meth:`socket.socket.connect` now waits until the connection |
| completes instead of raising :exc:`InterruptedError` if the connection is |

| - Issue #14260: The groupindex attribute of regular expression pattern object |
| now is non-modifiable mapping. |
| |
| - Issue #23792: Ignore KeyboardInterrupt when the pydoc pager is active. |
| This mimics the behavior of the standard unix pagers, and prevents |
| pipepager from shutting down while the pager itself is still running. |

| and socket open until the garbage collector cleans them up. Patch by |
| Martin Panter. |

| insert(), and copy(). This allows deques to be registered as a |
| MutableSequence and it improves their substitutability for lists. |
| |
| - Issue #23715: :func:`signal.sigwaitinfo` and :func:`signal.sigtimedwait` are |
| now retried when interrupted by a signal not in the *sigset* parameter, if |
| the signal handler does not raise an exception. signal.sigtimedwait() |
| recomputes the timeout with a monotonic clock when it is retried. |

| importing a test module is now picklable. |
| |
| - Issue #22181: On Linux, os.urandom() now uses the new getrandom() syscall if |
| available, syscall introduced in the Linux kernel 3.17. It is more reliable |
| and more secure, because it avoids the need of a file descriptor and waits |
| until the kernel has enough entropy. |
| |
| - Issue #2211: Updated the implementation of the http.cookies.Morsel class. |
| Setting attributes key, value and coded_value directly now is deprecated. |
| update() and setdefault() now transform and check keys. Comparing for |
| equality now takes into account attributes key, value and coded_value. |
| copy() now returns a Morsel, not a dict. repr() now contains all attributes. |
| Optimized checking keys and quoting values. Added new tests. |

| Original patch by Demian Brecht. |
| |
| - Issue #23615: Modules bz2, tarfile and tokenize now can be reloaded with |
| imp.reload(). Patch by Thomas Kluyver. |
| |
| - Issue #23605: os.walk() now calls os.scandir() instead of os.listdir(). |
| The usage of os.scandir() reduces the number of calls to os.stat(). |

| instead relying on OpenSSL source being configured and ready to build. The |
| ``PCbuild\build_ssl.py`` script has been re-written and re-named to |
| ``PCbuild\prepare_ssl.py``, and takes care of configuring OpenSSL source |
| for both 32 and 64 bit platforms. OpenSSL sources obtained from |
| svn.python.org will always be pre-configured and ready to build. |
| |
| - Issue #21037: Add a build option to enable AddressSanitizer support. |
| |
| - Issue #19962: The Windows build process now creates "python.bat" in the |

| in a ncursesw directory. |

| |
| - Issue #22445: PyBuffer_IsContiguous() now implements precise contiguity |
| tests, compatible with NumPy's NPY_RELAXED_STRIDES_CHECKING compilation |

| |
| - Issue #22079: PyType_Ready() now checks that statically allocated type has |
| no dynamically allocated bases. |
| |
| - Issue #22453: Removed non-documented macro PyObject_REPR(). |
| |
| - Issue #18395: Rename ``_Py_char2wchar()`` to :c:func:`Py_DecodeLocale`, |
| rename ``_Py_wchar2char()`` to :c:func:`Py_EncodeLocale`, and document |
| 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(). |
| |
