Version 1.4.6 of the JSON implementation for Ruby, is out now. It aims to provide an alternative to XML, and supports UTF-16 surrogate pairs in order to generate the whole range of unicode code points. It is available as a pure Ruby variant, which relies on the iconv and the stringscan extensions, and as a C extension variant.

This is a bug fix release, which fixes some API problems. Please see the Changes file for more information.
