 * Fixed formatting error when checking nullable `DateTimeOffset` with 
 `BeWithin(...).Before(...)` - [#2312](https://github.com/fluentassertions/fluentassertions/pull/2312)
 * `BeEquivalentTo` will now find and can map subject properties that are implemented through an explicitly-implemented interface - [#2152](https://github.com/fluentassertions/fluentassertions/pull/2152)
+* Fixed that the `because` and `becauseArgs` were not passed down the equivalency tree - [#2318](https://github.com/fluentassertions/fluentassertions/pull/2318)
 
 ### Breaking Changes (for users)
 * Moved support for `DataSet`, `DataTable`, `DataRow` and `DataColumn` into a new package `FluentAssertions.DataSet` - [#2267](https://github.com/fluentassertions/fluentassertions/pull/2267)
