-NUnit Analyzers 4.0.1 - February 1, 2024
+NUnit Analyzers 4.1 - March 16, 2024
+
+This release of the Analyzers extends the suppression of nullable warnings to also respect assumptions - 
+expressed via `Assume.That`. Also nullable warnings are suppressed even in the context of the 
+null-forgiving operator `!`, and NUnit2010 is extended to also cover `is` pattern expressions - e.g.
+`is null` and more general integer patterns as `is < 0 or >= 1`.
+
+The release contains contributions from the following users (in alphabetical order):
