I was looking at this today and noticed that my offline help still showed an old version of that page. So I cleared my offline version and downloaded the help again. Now the downloaded
"timestamp" file says "20160411" and the bz2 file is:
-rw-rw-r-- 1 bb bb 29249535 Apr 11 2016 ../wiki.tar.bz2
Am I doing something wrong? This seems to be a very old version.
