The OISF development team is proud to announce Suricata 2.0beta1. This
is the first beta release for the upcoming 2.0 version.

This release greatly improved our HTTP handling by upgrading libhtp
support to 0.5.5 and by redesigning transaction handling, which
increases HTTP performance as well[1]. On the performance side, a large
CUDA overhaul greatly improves our GPU performance[2]. Also new in this
release is a DNS parser, logger and detection support.
