Just saw this today. Be careful if you were planning to rely only on the WAC for any low-altitude flights!
http://naco.faa.gov/content/naco/SpecialNotices/Obstructions_on_WACs.pdf said:World Aeronautical Charts (WAC) (1:1,000,000 scale) will only show obstructions that are 500’ Above Ground Level (AGL) or taller. Obstacles 499’ AGL or less will no longer be depicted on these charts. WAC CH-25 will be the first chart to reflect this specification change. Eventually all WACs will be revised. The final WAC to be published with this change will be CJ-27 on April 8, 2009.
This change in minimum charted obstacle height depiction on WACs was necessary due to the increase of aeronautical information. Over time, as more and more information is added, chart clutter becomes a concern that affects chart readability. Military, commercial and general aviation groups were consulted prior to this change and agreed that this revision was necessary for chart usability.
VFR Sectional (1:500,000 scale) and Terminal Area Charts (1:250,000 scale) will not be affected by this specification change. These charts will continue to depict obstructions of 200’ AGL and higher.
