[Boost-users] What's the status of unordered_map.hpp?

Hi, In http://www.boost.org/doc/libs/1_35_0/doc/html/boost_tr1/unsupported.html, it shows the header file is <boost/tr1/unordered_set.hpp> for unordered_set. But I only find the following two files in version 1.36.0. boost/unordered_map.hpp I'm wondering if unordered_map is not stable yet, so that I'd better avoid using it. Or it will be stable from version 1.36.0 on? Thanks, Peng
