Revised versions of maptools, a package for reading geographical data from shapefiles, and sp, a package with classes and methods for spatial data handling, have been released on CRAN. They are maptools release 0.5-1 and sp release 0.8-1.

The maptools package now depends on sp (>= 0.8), so that users of maptools will need both to update the package itself, and to install the sp package. All previous maptools classes and functions are still available, but users are encouraged to try out the cleaner and more robust versions in sp.

Further details of changes (particularly incompatible changes in sp) are available on the R-sig-geo mailing list (see the "Spatial" task view on CRAN), and at http://r-spatial.sourceforge.net
