 * `iproto.Feature` type used instead of `ProtocolFeature`.
 * `iproto.IPROTO_FEATURE_` constants used instead of local ones.
 
+#### Schema changes
+
+`ResolveSpaceIndex` function for `SchemaResolver` interface split into two: 
+`ResolveSpace` and `ResolveIndex`. `NamesUseSupported` function added into the 
+interface to get information if usage of space and index names is supported.
