Google has begun pushing out new PageRank values to the Google Toolbar yesterday. This would make the first Toolbar PageRank update of 2013.
Normally Google updates PageRank values in the Google Toolbar every 3 months or so. The previous update was in November 2012 and before that in August 2012.
Despite PageRank still being part of the algorithm, SEOs know that toolbar PageRank is often outdated and not that useful. In addition, there are many other factors part of the algorithm that may or may not be as important as PageRank.
Even though, I hope your PageRank values increased and did not decline.
