RcppArmadillo 0.2.28
Armadillo 2.2.1 came out today (and it looks like 2.2.0 was skipped, tst, tst). It has now been wrapped into release 0.2.28 of RcppArmadillo which is already on CRAN.
The NEWS entry is below; a number of these changes were already in the preceding 0.2.27 release of RcppArmadillo which was base on the beta for Armadillo 2.2.0.

0.2.28 2011-08-02 o Upgraded to Armadillo release 2.2.1 "Blue Skies Debauchery" * faster multiplication of small matrices * faster trans() * faster handling of submatrices by norm() * added economical singular value decomposition: svd_thin() * added circ_toeplitz() * added .is_colvec() & .is_rowvec() * fixes for handling of complex numbers by cov(), cor(), running_stat_vec

CRANberries provides a diffstat report for 0.2.28 relative to 0.2.27. 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.
