Google Pagerank toolbar updated?

Updated: 24 June, 2014 seen 682

I have red in many places, that Google is not updating Pagerank this year anymore, and probably it will lose it's effect at all. But yesterday I noticed that my blog went from N/A to 0. And noticed that some other websites went up, and some went down. 

Don't know what actually it means - should I be happy for my 0, or not to pay attention to that at all?
