You can download the page and use awk and friends to the highest
value, e.g. 

----------------------------------------------------------------------
URL='http://tenet.dl.sourceforge.net/project/unetbootin/UNetbootin/'

wget -q -O- "$URL" | \
awk -F '"|/' '/^<tr class/ && !/Custom/ {print $4 }' | \
sort -n | tail -1
----------------------------------------------------------------------
