@@ -10,6 +10,7 @@ Enhancements:
 - Minimally improved support for methods having `ref struct` parameter and return types, such as `Span<T>`: Intercepting such methods caused the runtime to throw `InvalidProgramException` and `NullReferenceException` due to forbidden conversions of `ref struct` values when transferring them into & out of `IInvocation` instances. To prevent these exceptions from being thrown, such values now get replaced with `null` in `IInvocation`, and with `default` values in return values and `out` arguments. When proceeding to a target, the target methods likewise receive such nullified values. (@stakx, #665)
 - Restore ability on .NET 9 and later to save dynamic assemblies to disk using `PersistentProxyBuilder` (@stakx, #718)
 - Configure SourceLink & `.snupkg` symbols package format (@Romfos, #722)
+- Support for C# `with { ... }` expressions. Cloning a record proxy using `with` now produces another proxy of the same type (instead of an instance of the proxied type, as before). The cloning process can still be changed by intercepting the record class' `<Clone>$` method. (@stakx, #733)
 - Dependencies were updated
