Release 0.8.4 is now on CRAN (with a little delay due to vacations, and we
even got lucky in getting it out now rather than at the end).  The relevant
NEWS entry is below.  

0.8.4   2010-07-09

    o   new sugar vector functions: rep, rep_len, rep_each, rev, head, tail,
        diag
        
    o   sugar has been extended to matrices: The Matrix class now extends the 
        Matrix_Base template that implements CRTP. Currently sugar functions 
        for matrices are: outer, col, row, lower_tri, upper_tri, diag

    o   The unit tests have been reorganised into fewer files with one call
        each to cxxfunction() (covering multiple tests) resulting in a
        significant speedup

    o   The Date class now uses the same mktime() replacement that R uses
        (based on original code from the timezone library by Arthur Olson)
        permitting wide date ranges on all operating systems

    o   The FastLM/example has been updated, a new benchmark based on the
        historical Longley data set has been added

    o   RcppStringVector now uses std::vector<std::string> internally
    
    o   setting the .Data slot of S4 objects did not work properly
