Love this plugin!
Problem I'm facing is related to the "Number of Posts" option. I wanted to show all, so I set it to 100.
If I exclude current year posts, it seems to work great - it shows all the posts from the past years, today for example I think it showed 8 different posts.
If I don't exclude the current year though, it adds a blank line "2011: " after all the correct posts. So it showed the previous 8, but the 2 I posted today and then a blank line with just 2011.
