The OISF development team is pleased to announce Suricata 2.0.9. This release fixes a number of issues in the 2.0 series.

Couple of important fixes: defrag evasion, a crash when using certain rules (mixing regular content and relative bytejumps with dce option) and better detection of TCP retransmissions with different data.
