+# (!) Version 0.6 notes
+ 
+New version of value links is included. There are breaking changes.
+
+`new Link( value, x => ... )` doesn't work any more, use `Link.value( value, x => ... )` instead.
+
+There are absolutely exciting new links features. Please, refer to [NestedLink documentation](https://github.com/Volicon/NestedLink) for details.
