dechronization: Hey R Users! Time to Update ape

The ape package written by Emmanuel Paradis is the foundation for phylogenetic analyses in R. Yesterday, Paradis and his coauthors posted a new version (3.2) on the CRAN archive yesterday. There don't seem to be too many new functions, but there are some important bug fixes. One these - preventing calculation of negative state probabilities when reconstructing discrete character states - solves one of the more vexing problems I've had with the ace function. You should definitely get the update if you're doing ancestral reconstruction of discretely coded traits! Now we just need to hope the April 17th upgrade to R 2.9 goes smoothly...
