There is a new version of phytools (phytools 0.2-80) now available on CRAN. It will probably take a few days for the Mac OS & Windows binaries to be compiled and to percolate through the mirror repositories.
Relative to the most recent CRAN build of phytools (phytools 0.2-70), this version has only a couple of significant updates, as follows:
1. A bug fix in make.simmap(..., type="mcmc"), described here.
2. The addition of the option to plot trees in a circular (type="fan") style to plotSimmap, plotTree, contMap, and densityMap (described here: 1, 2, 3, 4, 5, 6, 7, and 8).
