Jax is referring to the fact that you cannot view the former changelogs. So for example if Jax meant to look at the changes for ES 1.2.9 but before getting a chance the changes for ES 1.2.10 come out, Jax cannot view the ES 1.2.9 changes. I'm usually on the ball with this, but I have had a case or two where I was like "what did I miss".
