+### Improvements
+
+- Adds factory methods for Configuration axis scope filters
+
+### More ways to create ScopeFilter for Configuration axis
+
+To create configuration axis `ScopeFilter` one has to provide actual configurations
+to filter by. However it's not always possible to get hold of one. For example
+`Classpaths.interSort` returns configuration names.
+For cases like that there are now `inConfigurationsByKeys` and `inConfigurationsByRefs` to create `ScopeFilter`'s
