| 
| But as this release is also available ready via GitHub and the RcppCore drat
| repo, you can install it now from the drat repo at
| 
|       http://rcppcore.github.io/drat/
| 
| via a simple
| 
|       drat::addRepo("RcppCore")
|       install.packages("RcppArmadillo")
| 
| or even just
| 
|       install.packages("RcppArmadillo", type="source",
|                        repo="https://RcppCore.github.io/drat")

| Thanks,  Dirk

| 
|     -   faster handling of sparse matrices by `kron()` and `repmat()`
| 
|     -   faster transpose of sparse matrices
| 
|     -   faster element access in sparse matrices
| 
|     -   faster row iterators for sparse matrices
| 
|     -   faster handling of compound expressions by `trace()`
| 
|     -   more efficient handling of aliasing in submatrix views
| 
|     -   expanded `normalise()` to handle sparse matrices
| 
|     -   expanded `.transform()` and `.for_each()` to handle sparse
|         matrices
| 
|     -   added `reverse()` for reversing order of elements
| 
|     -   added `repelem()` for replicating elements
| 
|     -   added `roots()` for finding the roots of a polynomial
| 
| -   Fewer LAPACK compile-time guards are used, new unit tests for
