+### Features
+* Added regexp supporting to interceptor
+   Examples:
+   - the interceptor route **"/dummies"** corresponds to all of this routes **"/dummies"**, **"/dummies/check"**, **"/dummies/test"**
+   - the interceptor route **"/dummies$"** corresponds only for this route **"/dummies"**. The routes **"/dummies/check"**, **"/dummies/test"** aren't processing by interceptor
+   Please, don't forgot, route in interceptor always automaticaly concateneted with base route, like this **service_base_route + route_in_interceptor**. 
+   For example, "/api/v1/" - service base route, "/dummies$" - interceptor route, in result will be next expression - "/api/v1/dummies$"
 ## <a name="1.4.4"></a> 1.4.4 (2021-08-30)
