Here is an interesting feature that has existed in Blink. For anyone that did not know, AFTER you do an manual update of Blink and it completes, you are left with the "Update Summary" window showing the final status of the updates. If you select one of them and then click on the Details button in the lower right of the screen, you will see information regarding what the update included in it. Not a lot is shown for the Antivirus Engine when it updates, but if you receive an update for the Blink portion, the output is quite interesting.
After doing an manual update on my Blink Server Edition, I noted the following bit of information for the Blink module after clicking on the Details button:

I have noticed a lot of times you will find out about new Zero Days (that you did not know existed) from eEye. Pretty neat simple trick. Keep in mind though, you must do this right after you update Blink. If you close the window and come back in again and attempt to use the Details button, nothing will be available to look at anymore.
