Release notes link - no access

The release notes for 4.1.13 have a link to this page, but I get this message.   Sorry, there is a problem This forum is only available to those logged in with a client account. If you are a current IPS client and are seeing this message, please log outand then log in with the same email and password that you use for the client area. If you need assistance logging in as a client please submit a ticket and we will be happy to assist. Error code: 2F173/H
I confirm what @Colonel_mortis wrote, that is exactly my case, I make IPS apps for my private use. I've no idea why IPS restricts me to see breaking changes, and I am forced to go through code comparison to see if and how I am affected.
