People have asked me to put JNOS 2.0 sources on github, so here you go.

 The official JNOS 2.0 site will always be :

Note that JNOS now has a WinRPR interface, several users have confirmed
it is working quite well.

Even bigger news (as of this evening), I have completed a prototype IP Bridge
interface for the EA5HVK VARA HF software modem, using PPP. This lets you use
internet protocols between 2 JNOS stations linked by VARA HF software modems.
  (the code needs cleaning up and documentation is in the works)

Has not been uploaded to GITHUB yet, see the official rsync site intead.

 The 2.0n (and 2.0n.beta) work has been shelved, in favour of just going
 back to 2.0m and at some point releasing a JNOS 2.0 security kit, which
 people can slap on top of any 2.0m or later release. Unfortunately, the
 the 2.0n release was simply getting out of hand, and too complicated.
