 ## Changes to the language {#language}
 
-
+Go 1.24 now fully supports [generic type aliases](/issue/46477): a type alias
+may be parameterized like a defined type.
+See the [language spec](/ref/spec#Alias_declarations) for details.
+For now, the feature can be disabled by setting `GOEXPERIMENT=noaliastypeparams`;
+but the `aliastypeparams` setting will be removed for Go 1.25.
