+- Major change: Enable SVE & SVE2 builds and make it a supported architecture! (thanks to @abondarev84)
+- Fix various clang-related bugs
+- Fix Aarch64 bug in Parser.rl because of char signedness. Make unsigned char the default in the Parser for all architectures.
+- Fix Power bug, multiple tests were failing.
+- C++20 related change, use prefixed assume_aligned to avoid conflict with C++20 std::assume_aligned.
+
+## [5.4.8] 2022-09-13
+- CMake: Use non-deprecated method for finding python by @jth in #108
+- Optimize vectorscan for aarch64 by using shrn instruction by @danlark1 in #113

+
+## [5.4.6] 2022-01-21
+- Major refactoring of many engines to use internal SuperVector C++ templates library. Code size reduced to 1/3rd with no loss of performance in most cases.
+- Microbenchmarking tool added for performance finetuning
+- Arm Advanced SIMD/NEON fully ported. Initial work on SVE2 for a couple of engines.
+- Power9 VSX ppc64le fully ported. Initial port needs some optimization.
+- Clang compiler support added.

+## [5.4.2] 2023-04-19
+- 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.
+
+## [5.4.1] 2023-02-20
+- The Intel Hyperscan team is pleased to provide a bug fix release to our open source library.
+  Intel also maintains an upgraded version available through your Intel sales representative.
+- Bugfix for issue #184: fix random char value of UTF-8.
+- Bugfix for issue #291: bypass logical combination flag in hs_expression_info().
+- Bugfix for issue #292: fix build error due to libc symbol parsing.
+- Bugfix for issue #302/304: add empty string check for pure literal API.
+- Bugfix for issue #303: fix unknown instruction error in pure literal API.
+- Bugfix for issue #303: avoid memory leak in stream close stage.
+- Bugfix for issue #305: fix assertion failure in DFA construction.
+- Bugfix for issue #317: fix aligned allocator segment faults.
+- Bugfix for issue #350: add quick validity check for scratch.
+- Bugfix for issue #359: fix glibc-2.34 stack size issue.
