+# Changelog
+
+## [1.0.0.0] - 2021-11-20
+
+### Changed
+
+* Compatibility with `genvalidity >= 1.0.0.0`
+
+### Removed
+
+* `genValidityBench`
+* `genUncheckedBench`
+
+## [0.2.0.0] - 2020-05-05
+
+### Added
+
+* genBenchSized
+
+### Changed
+
+* Benchmarking now happens with sizes 15 and 30 instead of 8,16,32,64.
+  The reasoning is that you only need to see if the time stays constant or not, and what the time is for a generator with the default size 30
+* Fixed a memory leak by using pure and deterministic generation instead of using IO-based pseudorandom generation.
+
+## [0.1.0.0] - 2020-04-17
+
+### Added
+
+* genBenchSizes
+
+### Changed
+
+* genValidBench, genUncheckedBench and genValidityBench now benchmark with multiple sizes
