+  submit a coroutine to a loop from another thread, returning a
+  concurrent.futures.Future.  By Vincent Michel.

+  avoid compatibility shims.
+
+- 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 zero (ROUND_DOWN). 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 #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 #24982: shutil.make_archive() with the "zip" format now adds entries
+  for directories (including empty directories) in ZIP file.
+
+- Issue #24857: Comparing call_args to a long sequence now correctly returns a
+  boolean result instead of raising an exception.  Patch by A Kaptur.

+  Based on patch by John Leitch.
+
+- Issue #24917: time_strftime() buffer over-read.
+
+- Issue #23144: Make sure that HTMLParser.feed() returns all the data, even
+  when convert_charrefs is True.
+
+- Issue #16180: Exit pdb if file has syntax error, instead of trapping user
+  in an infinite loop.  Patch by Xavier de Gaye.
+
+- Issue #21112: Fix regression in unittest.expectedFailure on subclasses.
+  Patch from Berker Peksag.
+
+- Issue #24931: Instances of subclasses of namedtuples have their own __dict__
+  which breaks the inherited __dict__ property and breaks the _asdict() method.
+  Removed the __dict__ property to prevent the conflict and fixed _asdict().
+

+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.

+  dialog rather than a separate dialog.   The former tabs are now a sorted
+  list.  Patch by Mark Roseman.

+  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.

+  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.

+  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.

+  font selections.  If there is a problem, edit $HOME/.idlerc/config-main.cfg
+  and remove 'fontxxx' entries from [Editor Window].  Patch by Mark Roseman.
+
+- Issue #21192: Idle editor. When a file is run, put its name in the restart bar.

+  selection or control(command) '-' or '+' or control-mousewheel.
+  Original patch by Lita Cho.
+
+- Issue #21597: The separator between the turtledemo text pane and the drawing

+  shrunk.  Original patches by Jan Kanis and Lita Cho.

+  was untested.
+
+- Issue #26015: Added new tests for pickling iterators of mutable sequences.
+
+- Issue #26325: Added test.support.check_no_resource_warning() to check that
+  no ResourceWarning is emitted.
+
+- Issue #25940: Changed test_ssl to use self-signed.pythontest.net.  This
+  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 #26583: Skip test_timestamp_overflow in test_import if bytecode

+Build
+-----
+
+- Issue #26884: Fix linking extension modules for cross builds.
+  Patch by Xavier de Gaye.
+
+- Issue #22359: Disable the rules for running _freeze_importlib and pgen when
+  cross-compiling.  The output of these programs is normally saved with the
+  source code anyway, and is still regenerated when doing a native build.
+  Patch by Xavier de Gaye.
+
+- Issue #27229: Fix the cross-compiling pgen rule for in-tree builds.  Patch
+  by Xavier de Gaye.
+
+- Issue #21668: Link audioop, _datetime, _ctypes_test modules to libm,
+  except on Mac OS X. Patch written by Xavier de Gaye.
+
+- Issue #25702: A --with-lto configure option has been added that will
+  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.
+
+- Issue #17603: Avoid error about nonexistant fileblocks.o file by using a

+  Bjoern Thiel.
+
+- Issue #26465: Update Windows builds to use OpenSSL 1.0.2g.
+
+- Issue #24421: Compile Modules/_math.c once, before building extensions.
+  Previously it could fail to compile properly if the math and cmath builds
+  were concurrent.
+
+- Issue #25348: Added ``--pgo`` and ``--pgo-job`` arguments to
+  ``PCbuild\build.bat`` for building with Profile-Guided Optimization.  The
+  old ``PCbuild\build_pgo.bat`` script is now deprecated, and simply calls
+  ``PCbuild\build.bat --pgo %*``.
+
+- Issue #25827: Add support for building with ICC to ``configure``, including
+  a new ``--with-icc`` flag.
+
+- Issue #25696: Fix installation of Python on UNIX with make -j9.

+
+- Issue #25136: Support Apple Xcode 7's new textual SDK stub libraries.
+
+- Issue #24324: Do not enable unreachable code warnings when using
+  gcc as the option does not work correctly in older versions of gcc
+  and has been silently removed as of gcc-4.5.
+
+Windows
+-------
+
+- Issue #27053: Updates make_zip.py to correctly generate library ZIP file.
+
+- Issue #26268: Update the prepare_ssl.py script to handle OpenSSL releases

+  32bit Python

+  distro.

+Tools/Demos
+-----------
+
+- Issue #26799: Fix python-gdb.py: don't get C types once when the Python code
+  is loaded, but get C types on demand. The C types can change if
+  python-gdb.py is loaded before the Python executable. Patch written by Thomas
+  Ilsche.
+
+- Issue #26271: Fix the Freeze tool to properly use flags passed through
+  configure. Patch by Daniel Shaulov.
