A new version of vegan was submitted to CRAN today. This is a minor bugfix release that cures some rare cases. The major bug fixes are:

- varpart4() failed if called directly instead of being called via varpart(). Most users do not call varpart4() directly so that this error probably does not hit many people. However, it hit Guillaume Blanchet who reported the bug. Thanks!

- plot.cca, text.cca, points.cca, plot.envfit failed in automatic scaling of arrows if axes were reversed (like xlim = c(1, -1)), or the origin of the bunch of arrows was shifted (like at = c(1,1)) in plot.envfit. I guess most people did not know that you can reverse axes and therefore this was unnoticed for a long time.

- plot.procrustes could fail if two compared configurations were identical!

A more major change is that permuted.index2 and associates were upgraded to the current development version. This brought along a couple of fixes in rare cases (like only two rows in a grid), and added function allPerms for complete enumeration of all possible permutations when this is feasible. The code is still experimental and only used in permDisper, but we plan to make all permutations to use this code in the future, and user comments are welcome.
