A new RcppArmadillo release is now out, below is a text copy (without links)
of what is at http://dirk.eddelbuettel.com/blog/

   RcppArmadillo 0.3.900.0                                                                                   

   A Armadillo release 3.900.0 was provided by Conrad yesterday. It has been
   rolled into a new RcppArmadillo release 0.3.900.0 which is now on CRAN and
   in Debian.
   It has a number of nice changes, mostly on the performance side of things
   (see below) and a minor cleanup/improvement in our Kalman filter example
   (which, as I just realized, I forgot to note in the \code{NEWS.Rd} in the
   released tarball):
     Changes in RcppArmadillo version 0.3.900 (2013-06-04)                                                   
       * Upgraded to Armadillo release Version 3.900.0 (Bavarian Sunflower)                                  
            * added automatic SSE2 vectorisation of elementary expressions
              (eg. matrix addition) when using GCC 4.7+ with -O3 optimisation
            * added support for saving & loading of cubes in HDF5 format,
              contributed by Szabolcs Horvat
            * faster median(), contributed by Ruslan Shestopalyuk
            * faster handling of compound expressions with transposes of
              submatrix rows
            * faster handling of compound expressions with transposes of
              complex vectors
       * Kalman filter example switched from inline to \code{sourceCpp},
         which simplifies / streamlines the C++ side a little
   Courtesy of CRANberries, there is also a diffstat report for the most
   recent release As always, more detailed information is on the
   RcppArmadillo page. Questions, comments etc should go to the rcpp-devel
   mailing list off the R-Forge page.
