I'm always more interested in improvements in coverage than valuations and this year Portugal's Ceres stamps have been reorganized (which has involved some renumbering). The 2014 edition will extend this treatment to the Portuguese Colonies. I remember early on finding some marked differences in coverage for the various colonies so this is good news. (This is of some importance to the Blue Volume 1 collector as it helps explain the differences in what is included in the album.)
Along with Portugal, there are also improvements in the Tiger Heads of Afghanistan. Airmail semi-Official stamps for Bavaria and Germany appear for the first time, as do the five-ring numeral cancellations for Baden. New Zealand has 45 new minor varieties, Alaouites 37 and Bolivia 22.
