ANNOUNCE: fping 4.0

[David Schweikert]

Hi,

I have just released fping 4.0.

It's a major new version, whose main feature is the unification of the
fping and fping6 binaries. Also, it brings long options, better timeout
handling, and other changes.

See here for the full release notes and a download link:

Cheers
