Google Updated Panda OR Penguin?

Hi

In past week, I lost keyword ranking for my website like anything. Previously my keywords were on first page but on Friday suddenly decreased ranking position to 10th page. Some blog talks about there were new panda or penguin update and because of that most of website lost their ranking.

But no one sure about confirmation about any new Google update. Google also not updated news related to it.

So is anyone know about it, how i got penalized for ranking of my keyword?

Is there any Panda or Penguin updated?
