Earlier this week, Conrad Sanderson issued a minor bug fix release 2.0.2 of his
Armadillo library which provides
templated C++ code for linear algebra. We wrapped that into a new
release 0.2.26 and shipped it to CRAN.
Due to it being summer and the otherwise
tirelesss human operator
behind the curtain being on a well-deserved vacation, it sat in the incoming
queue til this morning—but is now on CRAN.
Conrad did not rest either and just yesterday released version 2.1.91 as a
first step towards a new 2.2.0 release sometime soon. And also
yesterday, we wrapped that new version into
release 0.2.27. With
being back in full swing, we pushed it over there this morning and it already
made its way into the repository.
