This is the second pre-release of 3.4.0 which I hope to have out in
the next week or two. There's a lot of bug fixes and improvements
(mostly related to performance) and a few major changes. The biggest
change is completely removing libnet as an (optional) dependancy from
Tcpreplay. As any long-time subscriber to tcpreplay-users knows, I've
had a love-hate relationship with libnet, and I'm thrilled to replace
it with libdnet which seems to have fewer bugs and is still being
maintained. Libdnet is also required for fragroute support in
tcprewrite, so this should reduce the number of dependencies some
platforms have.
High-speed performance has also been improved via the new --pps-multi
option which allows sending multiple packets at a time without
sleeping in packets/sec mode.
Here's the current changelog of what's new in pre2 since 3.3.2:
- Add libdnet and remove libnet support for sending packets (#302)

There are still some open 3.4.0 tickets for tcpbridge which you can see here:

It would be great for people to kick the tires so-to-speak and report
any bugs so that I can fix them in time for the official 3.4.0
release.
