What's new in this version:
Core and Builtins:
- Issue #21418: Fix a crash in the builtin function super() when called without argument and without current frame (ex: embedded Python).
- Issue #21425: Fix flushing of standard streams in the interactive interpreter.
- Issue #21435: In rare cases, when running finalizers on objects in cyclic trash a bad pointer dereference could occur due to a subtle flaw in internal iteration logic. Library:
- Issue #10744: Fix PEP 3118 format strings on ctypes objects with a nontrivial shape.
- Issue #20998: Fixed re.fullmatch() of repeated single character pattern with ignore case. Original patch by Matthew Barnett.
- Issue #21075: fileinput.FileInput now reads bytes from standard stream if binary mode is specified. Patch by Sam Kimbrel.
- Issue #21396: Fix TextIOWrapper(..., write_through=True) to not force a flush() on the underlying binary stream. Patch by akira.
- Issue #21470: Do a better job seeding the random number generator by using enough bytes to span the full state space of the Mersenne Twister.
- Issue #21398: Fix an unicode error in the pydoc pager when the documentation contains characters not encodable to the stdout encoding. Tests:
- Issue #17756: Fix test_code test when run from the installed location.
- Issue #17752: Fix distutils tests when run from the installed location. IDLE:
- Issue #18104: Add idlelib/idle_test/htest.py with a few sample tests to begin consolidating and improving human-validated tests of Idle. Change other files as needed to work with htest. Running the module as __main__ runs all tests.

What's new in this version:
Core and Builtins:
- Issue #20588: Make Python-ast.c C89 compliant.
- Issue #20437: Fixed 21 potential bugs when deleting objects references.
- Issue #20538: UTF-7 incremental decoder produced inconsistant string when input was truncated in BASE64 section.
- Issue #20731: Properly position in source code files even if they are opened in text mode. Patch by Serhiy Storchaka.
- 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) Library:
- Issue #20778: Fix modulefinder to work with bytecode-only modules.
- Issue #20791: copy.copy() now doesn’t make a copy when the input is a bytes object. Initial patch by Peter Otten.
- Issue #20621: Fixes a zipimport bug introduced in 3.3.4 that could cause spurious crashes or SystemErrors when importing modules or packages from a zip file. The change causing the problem was reverted.
- 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 #20635: Fixed grid_columnconfigure() and grid_rowconfigure() methods of Tkinter widgets to work in wantobjects=True mode.
- Issue #19612: On Windows, subprocess.Popen.communicate() now ignores OSError(22, ‘Invalid argument’) when writing input data into stdin, whereas the process already exited.
- Issue #6815: os.path.expandvars() now supports non-ASCII environment variables names and values.
- Issue #17671: Fixed a crash when use non-initialized io.BufferedRWPair. Based on patch by Stephen Tu.
- Issue #8478: Untokenizer.compat processes first token from iterator input. Patch based on lines from Georg Brandl, Eric Snow, and Gareth Rees.
- Issue #20594: Avoid name clash with the libc function posix_close.
- Issue #19856: shutil.move() failed to move a directory to other directory on Windows if source name ends with os.altsep.
- 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 #18805: the netmask/hostmask parsing in ipaddress now more reliably filters out illegal values and correctly allows any valid prefix length.
- 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 #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.
- Issue #19186: Restore namespacing of expat symbols inside the pyexpat module.
- 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.
- Issue #20288: fix handling of invalid numeric charrefs in HTMLParser.
- Issue #20424: Python implementation of io.StringIO now supports lone surrogates.
- Issue #19456: ntpath.join() now joins relative paths correctly when a drive is present.
- Issue #19077: tempfile.TemporaryDirectory cleanup is now most likely successful when called during nulling out of modules during shutdown. Misleading exception no longer raised when resource warning is emitted during shutdown.
- Issue #20367: Fix behavior of concurrent.futures.as_completed() for duplicate arguments. Patch by Glenn Langford.
- Issue #8260: The read(), readline() and readlines() methods of codecs.StreamReader returned incomplete data when were called after readline() or read(size). Based on patch by Amaury Forgeot d’Arc IDLE:
- Issue #20406: Use Python application icons for Idle window title bars. Patch mostly by Serhiy Storchaka.
- Update the python.gif icon for the Idle classbrowser and pathbowser from the old green snake to the new new blue and yellow snakes.
- Issue #17721: Remove non-functional configuration dialog help button until we make it actually gives some help when clicked. Patch by Guilherme Simões Tests:
- Issue #20743: Fix a reference leak in test_tcl.
- Issue #20510: Rewrote test_exit in test_sys to match existing comments, use modern unittest features, and use helpers from test.script_helper instead of using subprocess directly. Patch by Gareth Rees.
- Issue #20532: Tests which use _testcapi are now marked as CPython only.
- Issue #19920: Added tests for TarFile.list(). Based on patch by Vajrasky Kok.
- Issue #19990: Added tests for the imghdr module. Based on patch by Claudiu Popa.
- Issue #20474: Fix test_socket “unexpected success” failures on OS X 10.7+.
- Issue #20605: Make test_socket getaddrinfo OS X segfault test more robust. Documentation:
- Issue #20488: Importlib is no longer an implementation of import, it’s the implementation. Build:
- Issue #20221: Removed conflicting (or circular) hypot definition when compiled with VS 2010 or above. Initial patch by Tabrez Mohammed.
- Issue #20609: Restored the ability to build 64-bit Windows binaries on 32-bit Windows, which was broken by the change in issue #19788. Tools/Demos:
- Issue #20535: PYTHONWARNING no longer affects the run_tests.py script. Patch by Arfrever Frehtes Taifersar Arahesis.
