+What's New in Python 3.6.0 alpha 1?
+===================================
+
+Release date: XXXX-XX-XX
+
+Core and Builtins
+-----------------
+
+- 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
+ converted to normal strings at run time. Given x=3, then
+ f'value={x}' == 'value=3'. Patch by Eric V. Smith.
+
+Library
+-------
+
+- Issue #22241: timezone.utc name is now plain 'UTC', not 'UTC-00:00'.
+
+- Issue #23517: fromtimestamp() and utcfromtimestamp() methods of
+ datetime.datetime now round microseconds to nearest with ties going to
+ nearest even integer (ROUND_HALF_EVEN), as round(float), instead of rounding
+ towards -Infinity (ROUND_FLOOR).
+
+- Issue #23552: Timeit now warns when there is substantial (4x) variance
+ between best and worst times. Patch from Serhiy Storchaka.
+
+- Issue #24633: site-packages/README -> README.txt.
+
+- Issue #24879: help() and pydoc can now list named tuple fields in the
+ order they were defined rather than alphabetically. The ordering is
+ determined by the _fields attribute if present.
+
+- Issue #24874: Improve speed of itertools.cycle() and make its
+ pickle more compact.
+
+- Fix crash in itertools.cycle.__setstate__() when the first argument wasn't
+ a list.
+
+- Issue #20059: urllib.parse raises ValueError on all invalid ports.
+ Patch by Martin Panter.
+
+- Issue #24360: Improve __repr__ of argparse.Namespace() for invalid
+ identifiers. Patch by Matthias Bussonnier.
+
+- Issue #23426: run_setup was broken in distutils.
+ Patch from Alexander Belopolsky.
+
+- Issue #13938: 2to3 converts StringTypes to a tuple. Patch from Mark Hammond.
+
+- Issue #2091: open() accepted a 'U' mode string containing '+', but 'U' can
+ only be used with 'r'. Patch from Jeff Balogh and John O'Connor.
+
+- Issue #8585: improved tests for zipimporter2. Patch from Mark Lawrence.
+
+- Issue #18622: unittest.mock.mock_open().reset_mock would recurse infinitely.
+ Patch from Nicola Palumbo and Laurent De Buyst.
+
+- Issue #24426: Fast searching optimization in regular expressions now works
+ for patterns that starts with capturing groups. Fast searching optimization
+ now can't be disabled at compile time.
+
+- Issue #23661: unittest.mock side_effects can now be exceptions again. This
+ was a regression vs Python 3.4. Patch from Ignacio Rossi
+
+- Issue #13248: Remove deprecated inspect.getargspec and inspect.getmoduleinfo
+ functions.
+
+IDLE
+----
+
++- 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 #24782: In Idle extension config dialog, replace tabs with sorted list.
+ Patch by Mark Roseman.
+
+- Issue #24790: Remove extraneous code (which also create 2 & 3 conflicts).
