Interesting, according to their book... "...depending on the release number and release date, there are not always binaries available..". So when there is a new release, it takes the binaries a while to catch up and they only release the binaries for current versions? Anyway, there is a new release today! Just when i get 2.0.0 working great... They also reference that www.rpnfind.net link in the official snort book as well, so I would mostly trust it.
Going to make a new install for 184.108.40.206 now. ;)
Note this line from snort.org "lots of NEW rules and tons of rule documentation"
