Below is a text version of the blog post.

RcppArmadillo 0.3.4.0
A new major released of Armadillo came out earlier today. I prepared the
corresponding RcppArmadillo package 0.3.4.0 which also arrived on CRAN
earlier today. This released contains a few performance improvements, the
beginnings of support of sparse matrices and more, see below. We also post
the NEWS entry for the beta release which was prepared, but not uploaded to
CRAN to minimise the upload frequency there. On the RcppArmadillo side, two
enhancements were made for the fastLm() function for faster linear model
fits.
Changes in RcppArmadillo version 0.3.4.0 (2012-09-06)
* Upgraded to Armadillo release 3.4.0 (Ku De Ta)
* added economical QR decomposition: qr_econ()
* added .each_col() & .each_row() for vector operations repeated on
each column or row
* added preliminary support for sparse matrices, contributed by Ryan
Curtin et al. (Georgia Institute of Technology)
* faster singular value decomposition via divide-and-conquer
algorithm
* faster .randn()
* NEWS file converted to Rd format
Changes in RcppArmadillo version 0.3.3.91 (2012-08-30)
* Upgraded to Armadillo release 3.3.91
* faster singular value decomposition via "divide and conquer"
algorithm
* added economical QR decomposition: qr_econ()
* added .each_col() & .each_row() for vector operations repeated on
each column or row
* added preliminary support for sparse matrices, contributed by Ryan
Curtin, James Cline and Matthew Amidon (Georgia Institute of
Technology)
* Corrected summary method to deal with the no intercept case when using
a formula; also display residual summary() statistics
* Expanded unit tests for fastLm
Courtesy of CRANberries, there is also a diffstat report for 0.3.4.0 relative
to 0.3.2.4 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.
