  20 # stable version is shown on:
  21 # https://dist.torproject.org/torbrowser/
  22 # except sometimes you get a new stable before it's
  23 # officially released, which is ok by me. for example,
  24 # right now, it has 6.5.2, but stable is 6.5.1.
  25 # we exclude verions with letters, as that seems to
  26 # be a relatively reliable indication of alpha/beta releases.
