RcppArmadillo 14.4.1-1 on CRAN: Small Upstream Fix
Armadillo is a powerful and expressive C++ template library for linear algebra and scientific computing. It aims towards a good balance between speed and ease of use, has a syntax deliberately close to Matlab, and is useful for algorithm development directly in C++, or quick conversion of research code into production environments. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 1236 other packages on CRAN, downloaded 39 million times (per the partial logs from the cloud mirrors of CRAN), and the CSDA paper (preprint / vignette) by Conrad and myself has been cited 620 times according to Google Scholar.
This release brings a small upstream bug fix to the two FFTW3-interfacing functions, something not likely to hit many CRAN packages.
The changes since the last and fairly recent CRAN release are summarised below.

Courtesy of my CRANberries, there is a diffstat report relative to previous release. More detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the Rcpp R-Forge page.
