A New PageRank Update Rolls Out by Google

For those of you who thought this was the end of nominal PageRank updates, well, it was not. Google is rolling a new update right now. Some people started noticing it yesterday, and I believe the ups and downs will continue over the weekend.
The last update had been on April 2010, so around nine months ago. That is quite a long time, especially if you consider at some periods in the past Google would roll a new PageRank update every three months or so.
The PR on most of my sites hasn’t changed a lot. Some of my niche sites gained 1 or 2 points, but that was it.
Judging by the comments on online forums I believe this update has an upward trend, as most people are seeing increases in their PageRanks.
