Few days ago, a new WordPress book has been released. Book is written by Chris Coyier and Jeff Starr and is available in PDF format, but the print version is expected soon. I have written book review, and you can win the free copy at Dev4Press website.
Last week I was very busy with other projects, so for this new release of GD Star Rating, you will get any fixed bugs. There were several bugs reported, and all now fixed. Few issues are still in works, so after I confirm the problems, they will be also fixed.
