Yes they are eliminating the credentialing year, but they have not decided when it will take effect and who will be included. So all I can say so far is stay tuned.
The way the credentialing year works now is that a resident has to have one year of post med school training before or beyond the four year required path training to sit for the boards. You can read all about it on the American Board of Path website. <a href="http://www.abpath.org" target="_blank">www.abpath.org</a>
Most people satisfy this requirement by doing a 5th year in path training, but research, conventional internship, and other things can count.
Personally I hope that they change it to four years for me so I can do a fellowship my 5th year. The way it is now if I want to become board certified in the fellowship I have to do it as a sixth year.
Sorry I am not much help on the changes yet but I am waiting with fingers crossed myself.
