Suricata 6.0.0 beta 1 released

We’re happy to announce Suricata 6.0.0 beta 1. This is a test version for a new major feature release of Suricata.

Originally planned to be released as a release candidate we wanted to get a few more interesting things in that are still a bit rough around the edges. So the plan is now to release 6.0RC1 early September and then the final late September.

We are hoping for some of you to take this beta and test it in your environment and report any issues to us.
