Github "releases" are based on tags. Yes, developers can change tags, though they should not. But it looks like they did in this case. You should follow the stealth update recipe and change the dist_subdir, since the distfile has changed. And examine the difference between the old 2.066 and the new 2.066 and decide whether users who have the old version should rebuild; if so, also increase the port's revision.
