-# NUnit Analyzers 4.8.1 - May 29, 2025
+# NUnit Analyzers 4.9 - June 11, 2025
+
+This release of the NUnit Analyzers adds several new analyzers. For the `RangeAttribute`,
+the analyzers now warn about potential issues at runtime.
+
+It also introduces an analyzer and code fix for translating
+`Assert.Multiple`/`Assert.MultipleAsync` into the new `Assert.EnterMultipleScope` format, as well
+as for converting `is T` checks into `Is.InstanceOf<T>()` constraints.
+
+For `NUnit2021`, the analyzer now respects `UsingPropertiesComparer`, including enhancements
+that will be available in NUnit 4.4.
+
+Finally, this release includes improvements to `NUnit2007`, `NUnit2045`, and `NUnit4002`.
+See the list of resolved issues below for more details.
