On January 1, 2012, Alaska and Rhode Island became the third and fourth states to ban the use of felt-soled waders in an effort to reduce the spread of the invasive algae, Didymo, and other invasive and noxious aquatic species. (The first two states are Maryland and and Vermont.)
A Missouri rule banning the waders in the state’s trout parks goes into effect March 1, 2012
Read about the Alaska ban in the Alaska Native News, here.
Read about the Rhode Island ban in the Rhode Island Striped Bass blog. (This regulation was passed so stealthily that I haven’t been able to find a brick-and-mortar news organization that covered it.)

Keep track of the news on felt-soled wader bans on a state-by-state basis at the Center for Aquatic Nuisance Species website, here. (And bookmark the site for future felt-soled wader ban questions.)
