A new upstream release 3.2.9 of Eigen is now reflected in a new RcppEigen release 0.3.2.9.0 which got onto CRAN late yesterday and is now going into Debian. Once again, Yixuan Qiu did the heavy lifting of merging upstream (and two local twists we need to keep around). Another change is by James “coatless” Balamuta who added a row exporter.

The NEWS file entry follows.

#### Changes in RcppEigen version 0.3.2.9.0 (2016-08-20)

• Updated to version 3.2.9 of Eigen (PR #37 by Yixuan closing #36 from Bob Carpenter of the Stan team)

• An exporter for RowVectorX was added (thanks to PR #32 by James Balamuta)

Courtesy of CRANberries, there is also a diffstat report for the most recent release.
