- Issue #4796: Added Decimal.from_float() and Context.create_decimal_from_float()
to the decimal module.
+- Fractions.from_float() no longer loses precision for integers too big to
+ cast as floats.
+
- Issue #4812: add missing underscore prefix to some internal-use-only
constants in the decimal module. (Dec_0 becomes _Dec_0, etc.)
+- Issue 4790: The nsmallest() and nlargest() functions in the heapq module
+ did unnecessary work in the common case where no key function was specified.
+
- Issue #4702: Throwing a DistutilsPlatformError instead of IOError in case
