Making your own "new Feature" window

Been having some trouble reaching out to the users with our own "new releases" and the information about our own fixes and new functionality. Looking at the community I realized that I wasn't alone with this problem. Today people are getting flooded with information through email so we threw that idea out the window. We also tried to publish the releases with knowledge articles, but the success hasn't been overwhelming.

So now I was thinking that perhaps we should do like ServiceNow and throw up a popup windows when user logs in. And this is how I did it.
