Philatelic Exporter review, courtesy of David Rennie (January 2010):

Last reviewed in the December 2008 Exporter, this volume has some 11,000 price changes, over half of which are in the postal issues, some 1500 in the Revenues and the others spread through the other sections, notably FDCs, Booklet Panes, Locals, Proofs, Canal Zone, Hawaii, Philippines and the UN sections.

Although as usual classic rarities and varieties in fine condition are up, many mint stamps from 1870 are down including the Columbians, Mississippi and other sets, with 20% decreases not being unusual.  By contrast fine used copies of the early classics and the popular sets show increases

In the modern era prices are relatively stable, but many Plate Blocks show increases, particularly the very modern issues with water-activated gum.

There are several editorial changes. In particular the terminology and listing of modern tagged issues with "mottled" appearance has been revised, with some items now being relegated to footnotes, and main numbers only given to those stamps printed with embedded tagging on uncoated paper.

There are many new error listings including the recently discovered 1¼c imperforate Palace of Governors coil, found 49 years after it was issued.  Some important additions in the Essays and Proofs sections include listings of the 1861-63 2c-90c Definitives on goldbeater's skin, and 1867 "Z" grill experimental essays.

As usual James Kloetzel's informative editorial letter gives more details, and page 85A the specifics of actual Scott numbers affected.

Some 2500 new colour scans have been incorporated in this edition, some replacing previous black and white, or poor colour impressions, others now illustrating items not previous illustrated.
