+## NUnit 3.13.3 - March 20, 2022
+
+This release includes several performance enhancements. [@lahma](https://github.com/lahma) provided a massive speed improvement for large parametrized test suites. In addition, quivalency tests with large unsortable collections run faster by determining if the collections are sortable before attempting to sort them.
+
+We've added several fixes for .NET 6.0 and we've stopped testing NUnit against .NET Core 2.1 which is now out of support.
+
+There are also several fixes for the new `FixtureLifeCycle` feature and other smaller bug fixes and performance improvements.
+

 ## NUnit 3.13.2 - April 27, 2021
 
 This release fixes a new issue with the `FixtureLifeCycle` attribute where `IDisposable` test fixtures were not being disposed properly. As always, [@gleb-osokin](https://github.com/gleb-osokin) has been a great help with this new feature.
