+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 #23517: fromtimestamp() and utcfromtimestamp() methods of

+

+ determined by the _fields attribute if present.

+ pickle more compact.
