v1.16 was released in 2006. Although there were previous versions (I think v1.06 (winter 2004?) was the first public multiplayer version), the HU community didn't use this website until 2009 after a split in the community (look up the AfterMath mod to see how the other community evolved, it's undoubtedly a decent mod to try).
I think v1.16 is the version you were expecting, it has the Cleansing oSkill on Leviathan armor (it was needed for curse immunity, maybe along with the Fade proc on Spirit Ward shield).
I've run the webpage maker over the text files (after a minimum of edits to allow it to work, note that there might be some minor errors in the result), I hope those let you enjoy the mod even more.
