 All notable changes to this project will be documented in this file.
 
+## [0.0.1-RC3]
+- Simplified NamespaceDataSource to use a supplier instead of hierarchy for static and dynamic source
+- LeiaBundle: Fixed duplicate instantiation of schema repository
+- TimeBasedDataProvider: Fixed the initial delay of executor to prevent multiple invocation of update on startup
+- Schema Validator: Removed instance creation of schema class. It's not required for static validations.
+- SchemaValidationUtils - Fixed strict type validation
+
 ## [0.0.1-RC2]
 - Added tests to the core functionality to schemaValidator, refresher, client, core and models
 - Fixed the validation bug in SchemaValidationUtils. field.getType().isInstanceOf is a miss, Class.isAssignable is the correct way to check for class assignments.
