+Features / APIs:
+
+- More algorithms support parallel and vector execution policies:
+    adjacent_difference, partition, reverse, reverse_copy, rotate_copy,
+    stable_partition.
+- More algorithms support parallel execution policies:
+    inplace_merge, partial_sort_copy.
+- Split algorithm declarations and implementation by files.

 - Aligned the implementation with the draft N4659 of the C++ standard.
     In particular, inner_product no longer supports execution policies.
-- reduce and transform_reduce support unseq and par_unseq execution 
+- reduce and transform_reduce support unseq and par_unseq execution
     policies if std::plus<> is used for reduction.
 - Added counting_iterator and zip_iterator to support advanced use cases.
    To use, include pstl/iterators.h header file.
