Hi all, We have just released Hyperscan v5.1.0 on Github at https://github.com/intel/hyperscan/releases We add DFA wide-state compression to reduce bytecode. We refined the interpreter and optimized pure literal matching scenarios. In addition, we fixed bugs in logical combinations and dependency issues. [5.1.0] 2019-01-31 New Features: - Improve DFA state compression by wide-state optimization to reduce bytecode size. - Improve interpreter runtime handling for pure literal patterns to boost the performance of pure literal matching. - Improve representation of interpreter to boost overall performance. Known Issues and Limitations: There are no known issues with this release. Resolved Issues: - Bugfix for logical combinations: fix error reporting combination's match in case of sub-expression has EOD match under streaming mode. - Bugfix for logical combinations: fix miss reporting combination's match under vacuous input. - Bugfix for issue #104: fix compile error with Boost 1.68.0. - Bugfix for issue #127: avoid pcre error for hscollider with installed PCRE package. - Update version of PCRE used by testing tools as a syntax and semantic reference to PCRE 8.41 or above. - Fix github repo address in doc. Thanks, Harry
