Hi all, We have just released Hyperscan 4.5.1 on GitHub. This is a bugfix release. After we released 4.5 last week, a few things were discovered that required fixes. [4.5.1] 2017-06-16 - Bugfix for issue #56: workaround for gcc-4.8 C++11 defect. - Bugfix for literal matching table generation, reversing a regression in performance for some literal matching cases. - Bugfixes for hsbench, related to multicore benchmarking, portability fixes for FreeBSD, and clarifying output results. - CMake: removed a duplicate else branch that causes very recent (v3.9) builds of CMake to fail. Regards, Matt.
