2_much, PR hasn't got stricter. Just rescaled. IOW a PR4 site now has the strength a PR5 site had before. This probably just is due to the highest PR10 site having a true value that was higher than before. The PR scale is just a logarithmic display of where a site ranks between pages with the base minimum PR (PR0) and the highest PR10.
