I stand corrected, this actually happened this morning, see

... I just pushed RcppArmadillo_0.2.27 into incoming on CRAN.  As before this
is a beta release to help Conrad to iron out any issues; should you see any
unexpected behaviour please feel free to report back here first. Rollbacks
are always available thanks to the archive/ section on CRAN as well as my
code directory at the URL below.

Cheers, Dirk

| 0.2.27  2011-07-22
| 
|     o   Upgraded to Armadillo release 2.1.91 "v2.2 beta 1"
| 
|           * faster multiplication of small matrices
|           * faster trans()
|           * faster handling of submatrices by norm()
|           * added economical singular value decomposition: svd_thin()
|           * added circ_toeplitz()
|           * added .is_colvec() & .is_rowvec()
| 
| 0.2.26  2011-07-17
| 
|     o   Upgraded to Armadillo release 2.0.2 
| 
|           * fix for handling of conjugate transpose by as_scalar()
|           * fix for handling of aliasing by diagmat()
|           * fix for handling of empty matrices by symmatu()/symmatl()
| 
| 0.2.25  2011-06-30
| 
|     o   Upgraded to Armadillo 2.0.1 which fixes two minor compilation issues
| 
| 0.2.24  2011-06-29
| 
|     o   Upgraded to Armadillo release 2.0.0 "Carnivorous Sugar Glider"
| 
|           * faster multiplication of tiny matrices (≤ 4x4)
| 	  * faster compound expressions containing submatrices
| 	  * faster inverse of symmetric positive definite matrices
| 	  * faster element access for fixed size matrices
| 	  * added handling of arbitrarily sized empty matrices (eg. 5x0)
| 	  * added loading & saving of matrices as CSV text files
| 	  * added .count() member function to running_stat and
| 	    running_stat_vec 
| 	  * added syl(), strans(), symmatu()/symmatl()
| 	  * added submatrices of submatrices
| 	  * det(), inv() and solve() can be forced to use more precise
| 	  * algorithms for tiny matrices (≤ 4x4)
| 	  * htrans() has been deprecated; use trans() instead
| 	  * API change: trans() now takes the complex conjugate when
| 	    transposing a complex matrix 
| 	  * API change: .is_vec() now outputs true for empty vectors
| 	    (eg. 0x1) 
| 	  * API change: forms of chol(), eig_sym(), eig_gen(), inv(), 
|             lu(), pinv(), princomp(), qr(), solve(), svd(), syl() that do not
| 	    return a bool indicating success now throw std::runtime_error
| 	    exceptions when failures are detected 
| 	  * API change: princomp_cov() has been removed; princomp() in 
|             conjunction with cov() can be used instead
| 	  * API change: set_log_stream() & get_log_stream() have been 
|             replaced by set_stream_err1() & get_stream_err1()
