So where do we download the Sage 50 CA SDK now?

SOLVED

So now that Sage has overhauled their website, I can no longer find a way to download the SDK. I used to be able to find it on the public facing site, but now they've made sure to make no mention of it. All the old links suggesting how to download the SDK are now obsolete. 

There used to be this link: https://support.na.sage.com/selfservice/viewContent.do?externalId=13102&sliceId=1. But it now describes a defunct process. 

I found this page but none of these links will work: https://support.na.sage.com/selfservice/viewContent.do?externalId=89239&sliceId=1. Do I need to log in somewhere to enable them? They appear to be blocked. You used to be able to just download them. So what now?

How do we go about getting the SDK these days? This process is never going to end if you have a Sage 50 integration. Every Sage 50 update, I need to do this. The process should be much easier than this.
