Well it looks like I forgot to announce the RcppArmadillo 0.3.0, and its
first follow-up. So the current version is -- reflecting Conrad's
3.0.2 release.

The NEWS entries since 0.3.0 are below, summarizing the nice changes his new
major release brough: 2012-04-19

    o   Upgraded to Armadillo release 3.0.2

    	  * fixes for handling diagonal matrices

    o   Undefine NDEBUG if it has been set (as R does) as this prevents a
        number of useful debugging checks. Users can still define it or
        define ARMA_NO_DEBUG if they want a 'non-development' build 2012-04-12

    o   Upgraded to Armadillo release 3.0.1

    	  * fixes for compilation errors
    	  * fixes for potential aliasing issues

0.3.0   2012-04-10

    o   Upgraded to Armadillo release 3.0.0 "Antarctic Chilli Ranch"

    	  * added non-contiguous submatrix views
    	  * added shorthand for inverse: .i()
    	  * added hist() and histc()
    	  * faster repmat()
    	  * faster handling of submatrix views with one row or column 
    	  * faster generation of random numbers
    	  * faster element access in fixed size matrices
    	  * better detection of vector expressions by sum(), cumsum(),
    	    prod(), min(), max(), mean(), median(), stddev(), var() 
    	  * expressions X=A.i()*B and X=inv(A)*B are automatically converted
    	    to X=solve(A,B)
