This release includes several performance enhancements. @lahma provided a massive speed improvement for large, parametrized test suites. In addition, equivalency 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.
This release fixes a new issue with the FixtureLifeCycle attribute where IDisposable test fixtures were not being disposed properly. As always, @gleb-osokin has been a great help with this new feature.
It also fixes a long-standing performance issue with CollectionAssert.AreEquivalent and the CollectionEquivalentConstraint when comparing large collections. The deep comparison that NUnit performs on the two collections will always have a worst case bound of O(n^2) but we have optimized it so that the majority of use cases will be closer to O(n).
We've also made significant optimizations to the OR filters for selecting tests using their full name. This dramatically improves test performance for large code bases that use dotnet test. Thanks to @pakrym for his help with this.
This release addresses several misses with the new FixtureLifeCycle attribute, switches to using SourceLink and NuGet snupkg packages for debugging into NUnit from your unit tests. It also addresses issues with the time format of ignored and explicit tests in the test results file.
The FixtureLifeCycle attribute has been added to indicate that an instance for a test fixture or all test fixtures in an assembly should be constructed for each test within the fixture or assembly.
This attribute may be applied to a test fixture (class) or to a test assembly. It is useful in combination with the Parallelizable Attribute so that a new instance of a test fixture is constructed for every test within the test fixture. This allows tests to run in isolation without sharing instance fields and properties during parallel test runs. This makes running parallel tests easier because it is easier to make your tests thread-safe.
This release also fixes several issues running tests in .NET 5.0. If your tests target .NET 5.0, we recommend updating to this release.
This release of NUnit finally drops support for .NET 2.0. If your application still targets .NET 2.0, your tests will need to target at least .NET 3.5. Microsoft ended support for .NET 2.0 on July 12, 2011. Microsoft recommends that everyone migrate to at least .NET Framework 3.5 SP1 for security and performance fixes.
This release dramatically improves NUnit support for async tests including returning ValueTask and custom tasks from tests, improved handling of SynchronizationContexts and better exception handling.
The .NET Standard 2.0 version of NUnit continues to gain more functionality that is found in the .NET 4.5 version of the framework like setting the ApartmentState and enabling Timeout on tests.

NUnit 3.10.1
Added a namespace to the props file included in the NuGet package to make it compatible with versions of Visual Studio prior to VS 2017.
