Suricata 3.2beta1 ready for testing

We’re happy to announce Suricata 3.2beta1. The plan is to release a release candidate within a few weeks, so please help us test this release!

This release includes a large detection engine rewrite that should make it much easier to extend Suricata with new keywords.

We’ve also converted the user guide to sphinx. Lots of work still to be done, but for a preview check
