Full Changelog: nsubstitute/NSubstitute@v6.1.0...v6.2.0

v6.1.0

NSubstitute v6.1.0

This release reverts nullability support introduced in 6.0. This change caused a number of problems for callers (#​973, #​976), and trying to resolve these (#​976) revealed the need for more fundamental changes to NSubstitute to effectively support this. As a result, nullability is again disabled for public API. Huge thanks to @​jdb0123, @​Romfos, and @​Moha-sami for their PRs addressing this, and thanks for all those who raised issues. We also humbly award @​zvirja with one unlimited "I told you so" pass to use as he sees fit.

What's Changed

• Add new argument matcher for comparing objects by reference by @​Wer-Wolf in #​963
• Revert nullability changes in #​985

New Contributors

• @​Wer-Wolf made their first contribution in #​963
