 ## vNext (TBD)
 
 ### Enhancements
-* None
+* Added support for customizing the ignore attribute applied on certain generated properties of Realm models. The configuration option is called `realm.custom_ignore_attribute` and can be set in a global configuration file (more information about global configuration files can be found in the [.NET documentation](https://learn.microsoft.com/en-us/dotnet/fundamentals/code-analysis/configuration-files)). The Realm generator will treat this as an opaque string, that will be appended to the `IgnoreDataMember` and `XmlIgnore` attributes already applied on these members. The attributes must be fully qualified unless the namespace they reside in is added to a global usings file. For example, this is how you would add `JsonIgnore` from `System.Text.Json`:
+
+  ```
+  realm.custom_ignore_attribute = [System.Text.Json.Serialization.JsonIgnore]
+  ```
+  (Issue [#2579](https://github.com/realm/realm-dotnet/issues/2579))
 
 ### Fixed
 * None
