Libtrace 4.0.0 Released

2016

Libtrace 4.0.0 is now out of beta and considered ready for general release.

We've fixed quite a few bugs over the course of the beta. More details can be found on the ChangeLog page on libtrace wiki. However, while we're no longer in beta, there may still be a few bugs out there -- don't hesitate to report any problems you find to us at contact [at] wand [dot] net [dot] nz.

Another major change since the beta release is that we've re-licensed libtrace and libpacketdump to be under the LGPL v3 (rather than the GPL v2). Hopefully this will encourage people who were turned off by the restrictions of the GPL to now adopt libtrace for their packet capture and analysis needs.

This version of libtrace includes an all new API that resulted from Richard Sanger's Parallel Libtrace project, which aimed to add the ability to read and process packets in parallel to libtrace. Libtrace can now also better leverage any native parallelism in the packet source, e.g. multiple streams on DAG, DPDK pipelines or packet fanout on Linux interfaces.

Please note that the old libtrace 3 API is still entirely intact and will continue to be supported and maintained throughout the lifetime of libtrace 4. All of your old libtrace 3 programs should still build and run happily against libtrace 4; please let us know if this turns out to not be the case so we can fix it!
