Hi all, We have just released Hyperscan 5.1.1 on GitHub. This is a bugfix release. A few things were discovered that required fixes after release 5.1. [5.1.1] - Add extra detection and handling when invalid rose programs are triggered. - Bugfix for issue #136: fix CMake parsing of CPU architecture for GCC-9. - Bugfix for issue #137: avoid file path impact on fat runtime build. - Bugfix for issue #141: fix rose literal programs for multi-pattern matching when no pattern ids are provided. - Bugfix for issue #144: fix library install path in pkg-config files. Thanks, Xiang
