I'm glad to announce that the post-review version of The Boost Multi-index Containers Library or Boos.MultiIndex (formerly known as Boost.IndexedSet) is available at: http://groups.yahoo.com/group/boost/files/multi_index.zip The most noticeable change is the new name for the library, which I hope will please most and bug none. Also, a new powerful feature called composite_key has been added. The complete list of changes after requests from the reviewers can be consulted at: http://groups.yahoo.com/group/boost/files/multi_index_postreview_notes.html I'd be grateful if the people interested could do the following: 1. make sure that all requests have been met. Those that haven't are justified at the post-review notes. 2. try to compile the library with different compilers. I don't think I've broken anything, but one never knows. This version has been tested with MSVC 6.5, GCC 3.3.1 and ICC 7.1 for Windows. Of special interest are MSVC 7.1, ICC 8.0, GCC 4.0 and CW 9.2. If no one raises any objection, in a week's time I'll commit the library to the main CVS, hopefully in time for Boost 1.32. Thanks everybody, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
