Core and builtins
-----------------
+- Added the future_builtins module, which contains hex() and oct().
+ These are the PEP 3127 version of these functions, designed to be
+ compatible with the hex() and oct() builtins from Python 3.0. They
+ differ slightly in their output formats from the existing, unchanged
+ Python 2.6 builtins. The expected usage of the future_builtins
+ module is:
+ from future_builtins import hex, oct
+
- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
exponents for exponents with absolute value < 100. Follows C99
standard. This is a change on Windows, which would use 3 digits.
