Google PageRank (PR)
Before 2013 the PR of a page has played a great role in the search rankings. PageRank is the popularity index of a page in terms of the links (0-10 scale). Google hasn't deleted this number yet, but you won't get the update this year, webpages are qualified by more important things these days. If you reached a certain PR with your page: don't worry, you will not lose any recognition, it will transform only!
7th of december 2013. There are still no changes in PageRank. PR is still alive so you should not surrender on that one.
