I've updated *Modern IDL* for some of the IDL 8.1 features, notably GRIB, function graphics enhancements[^1], and the `IDLffVideoWrite` class. PDF purchasers from this point on should get the new version and I will send out the update to the purchasers of the old PDF shortly. The first run of the print book is all sold; the second run is still at the printers. So if you order the print version right now, expect the book to ship sometime next week.
As always, see the [Modern IDL website][Modern IDL] for purchasing, new code examples, table of contents, sample chapter (object graphics with the new function graphics updates!), and errata.
[^1]: Also, I switch back to the term "function graphics", which was my original favorite term for the new graphics system, but I had gone away from it because there seemed to be consensus on the newsgroup to call it "new graphics." I think "function graphics" is a better term that is less likely to not make sense when the next graphics system comes out.
