[boost] [optional] Where are the fixes for self-assignment problem?

Several weeks ago I reported that boost::optional<T> was not safe under self-assignment. The author of the class said he was fixing the library, but no new versions of the code have been checked into the CVS repository. With the code freeze for boost 1.33 only a couple of weeks away, I was wondering whether optional<T> would be fixed on time. Joe Gottman
