Thanks Jeff, maybe I'm obsessed but even if I'm middle of writing a post and at the same time an update notification appears on the admin-bar, I can't finish my post unless I update the site first :) I remember TimThumb tsunami, by the time I was a very fresh WP learner, Though I'm not sure if I was using either a Woo or Elegant theme but I received an urgent newsletter from the theme vendor urging for an immediate update. I had no idea what's this all about anyhow I followed the instruction and luckily faced no issue.
