S-PLUS 4.0 complements -- intended for new users of the GUI.
Programming complements -- programming issues, including for 4.0.
Statistics complements -- further advanced statistical methods, mainly
using third-party library sections
Most of the new material is in the statistics complements, which now
cover local polynomial and spline methods for density, hazard and
spectral density estimation and for smoothing, and further tree-based
methods. There is also more material on correspondence analysis,
including multiple correspondence analysis.
The URL

will give a site near you (although Adelaide may be down). There are
PostScript and PDF versions, the latter with full hyperlinking.
(Making that work with the hyperref package has been a development
effort in itself). Scripts for the Complements code are in the
scripts collections for the book.
To support this, my SWin collection (http://www.stats.ox.ac.uk/pub/SWin,
http://lib.stat.cmu.edu/DOS/S/SWin) has new or revised entries
HARE, HEFT, hazcov, locfit, logspline, lspec, RPart, survcart, tssa
plus a couple of other ports (AIMD, princurv). These have all been
partially tested with 3.3 and 4.0, but I keep finding quirks of 4.0.
