GitHub files aren't updated to kill time. If you look at the commits, every commit message has some information along with it which explains what exactly the files are updated for. What scares me is, the last commit  was around July 7th https://github.com/epochtalk/epochtalk/pull/457/commits/91599ad083e33fc0314628fdae9c88f297894760 and not sure if the website is being actively developed.
