Google Penguin Update 2.1 

Google's head of search spam Matt Cutt announced a latest release of Penguin update 2.1 on 4th of Oct 2013. It is said to be believe that this second generation update is going to effect almost 1% of search queries. 

Still there are lot's of talks happening around this latest update, but nothing has been officially announced that what are the actual changes and how they are going to effect the search queries.

Penguin 2.0 version was released on 22nd of May 2013 which effected almost 2.3% of English queries. After the launch of penguin 2.0 Matt Cutt said that it was fourth launch related to penguin but Google claimed it to be penguin 2.0 release as it was a algorithm change not just a data refresh.

First Google penguin algorithm was launched in April 2012 which was focused on reducing the spamming activity on internet. Later Google release two different versions of algorithm in May and October of 2012.

As per webpronews.com Google's comment on initial launch of algorithm was "The change will decrease rankings for sites that we believe are violating Google’s existing quality guidelines. We’ve always targeted webspam in our rankings, and this algorithm represents another improvement in our efforts to reduce webspam and promote high quality content. While we can’t divulge specific signals because we don’t want to give people a way to game our search results and worsen the experience for users, our advice for webmasters is to focus on creating high quality sites that create a good user experience and employ white hat SEO methods instead of engaging in aggressive webspam tactics."
