+## [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.
