Vegan version 1.13-2 was submitted to CRAN on Tuesday, August 20, 2008. This is a minor release that only fixes obvious bugs and improves existing functions in the previous release. A major release (1.15-0) is tentatively scheduled for the Equinox, 2008, and it will contain most of the current package tree of vegan in R-Forge.

The most important fix is that the residual degrees of freedom in anova.cca are always found from the number of rows. This should close the df transition started in 1.13-0.

Other changes are detailed in the NEWS file of the package which also can be read using vegandocs() command in vegan.
