[boost] 1.59 release notes don't mention new property_tree::json_parser

The commit logs say:

    TL;DR: The new parser fixes long-standing bugs and has full
Unicode support, but removes non-standard extensions
   of the old parser, which could break code:
   - String concatenation: the old parser concatenated adjacent string
literals like C does.
   - Comments: the old parser supported C and C++-style comments. JSON
doesn't allow comments.

Removing support for comments did break something. Unfortunately there
was no sign of this in the release notes, so I had to debug it the
hard way (in code that swallowed the exception from the parser - gah!)
and only found the commit message once I already knew what the problem
was.
