- update to 5.4.2: * Roll back bugfix for github issue #350: Besides using scratch for corresponding database, Hyperscan also allows user to use larger scratch allocated for another database. Users can leverage this property to achieve safe scratch usage in multi-database scenarios. Behaviors beyond these are discouraged and results are undefined. * Fix hsdump issue due to invalid nfa type.

- Update to version 5.4.0 * Improvement on literal matcher "Fat Teddy" performance, including support for Intel(R) AVX-512 Vector Byte Manipulation Instructions (Intel(R) AVX-512 VBMI). * Introduce a new 32-state shuffle-based DFA engine ("Sheng32"). This improves scanning performance by leveraging AVX-512 VBMI. * Introduce a new 64-state shuffle-based DFA engine ("Sheng64"). This improves scanning performance by leveraging AVX-512 VBMI. * Introduce a new shuffle-based hybrid DFA engine ("McSheng64"). This improves scanning performance by leveraging AVX-512 VBMI. * Improvement on exceptional state handling performance for LimEx NFA, including support for AVX-512 VBMI. * Improvement on lookaround performance with new models, including support for AVX-512. * Improvement on DFA state space efficiency. * Optimization on decision of NFA/DFA generation. * hsbench: add CSV dump support for hsbench. * Bugfix for cmake error on Icelake under release mode. * Bugfix in find_vertices_in_cycles() to avoid self-loop checking in SCC. * Bugfix for issue #270: fix return value handling in chimera. * Bugfix for issue #284: use correct free function in logical combination. * Add BUILD_EXAMPLES cmake option to enable example code compilation. * Some typo fixing.

- Update to version 5.2.1 - Fix compile issue when `BUILD_SHARED_LIBS` is on in release mode. - Update to version 5.2.0 - Literal API: add new API `hs_compile_lit()` and `hs_compile_lit_multi()` to process pure literal rule sets. The 2 literal APIs treat each expression text in a literal sense without recognizing any regular grammers. - Logical combination: add support for purely negative combinations, which report match at EOD in case of no sub-expressions matched. - Fix uninitialized use of `scatter_unit_uX` due to padding. - Fix numerical result out of range error. - Avoid corruption of pending combination report in streaming mode. - Fix scratch free issue when memory allocation fails. - Builds are broken with LTO - disable for for now

- Update to version 5.1.0 * Improve DFA state compression by wide-state optimization to reduce bytecode size. * Create specific interpreter runtime handling to boost the performance of pure literal matching. * Optimize original presentation of interpreter (the "Rose" engine ) to increase overall performance. * 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. * Fix compile error with Boost 1.68.0. * 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. - Remove patch: * hyperscan-build.patch (fixed upstream)

(revision 5)
- Update to version 5.0.0 * Introduce chimera hybrid engine of Hyperscan and PCRE, to fully support PCRE syntax as well as to take advantage of the high performance nature of Hyperscan. * New API feature: logical combinations (AND, OR and NOT) of patterns in a given pattern set. * Windows porting: hsbench, hscheck, hscollider and hsdump tools now available on Windows 8 or newer. * Improve undirected graph implementation to avoid graph copy and reduce compile time. * Bugfix for issue #86: enable hscollider for installed PCRE package.
