So I said 173 was coming out this week... I was wrong.
First and foremost, this was a pretty dang accurate schedule. We had our banners done, email blast was ready to go and then.... the machines we use to build the actual update just had some major hardware issues during our building process.
Fortunately all the content was saved! Hurray! Bad news is the machine we worked on isn't alive anymore. Our IT team is currently building another machine to get things running again and once it's able to do so, the content will go live.
