Did You Know That Google Is Rolling a PageRank Update Over the Weekend

I wouldn’t be surprised to see Google rolling a PageRank update on April 1st, but it looks like they waited until the weekend to roll it out.
The update looks like a subtle one to me. In fact the homepage of most of my sites didn’t see any PR fluctuation. I discovered the update while browsing through my blog and finding that some recent posts have already gained PR.
What about you, did you see any major PageRank fluctuations on your sites or around the web?
One thing made me happy though: the consistency of the updates. Last one had taken place in January 02/03, so this one is being rolled exactly three months after. I hope Google will finally keep a regular pace with the PageRank updates, as this would give more certainty to webmasters.
