While I was out at the (immensely impressive and equally enjoyable) useR! 2014 conference at UCLA, Conrad provided a bug-fix release 4.320 of Armadillo, the nifty templated C++ library for linear algebra. I quickly rolled that into RcppArmadillo release 0.4.320.0 which has been on CRAN and in Debian for a good week now.

This release fixes some minor things with sparse and dense Eigen solvers (as well as one RNG issue probably of lesser interest to R users deploying the RNGs from R) as shown in the NEWS entry below.

Changes in RcppArmadillo version 0.4.320.0 (2014-07-03)

• Upgraded to Armadillo release Version 4.320 (Daintree Tea Raider)

  • expanded eigs_sym() and eigs_gen() to use an optional tolerance parameter

  • expanded eig_sym() to automatically fall back to standard decomposition method if divide-and-conquer fails

  • automatic installer enables use of C++11 random number generator when using gcc 4.8.3+ in C++11 mode

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.
