 ## [Unreleased]
 
+## [0.4.3] - 2022-06-19
+
+### Added
+
+- Add libFuzzer and AFL fuzzing boilerplate to find panics
+
+- Add artificial recursion limit during parsing to prevent stack exhaustion.
+  _This means that groups can be nested by at most 127 levels. I don't think you'll ever run into this limitation, but if you do, you can refactor your expression into variables._
+
+### Fixed
+
+- Fixed crash caused by slicing into a multi-byte UTF-8 code point after a backslash or in a string
+- Fixed crash caused by stack exhaustion when parsing a very deeply nested expression
+
