New beta versions are generally available only to registered users, but
if there are important interim bug fixes, beta versions may appear here.
- If you are using HyperNewt,
you may need to re-add HyperNewt info to any new entries (e.g., Notes) created by Newt or Sloup.
(this does not happen automatically with HyperNewt 2.01)

but initial install by system isn't quite right)
