• [BREAKING CHANGE] Replaced constructor parameter config with url in Listener class. The constructor is now only using a complete websocket url (e.g. http://localhost:3000/ws or ws://localhost:3000/ws) but not rest-gateway url anymore (It will NOT append /ws suffix to the input url).
• [BREAKING CHANGE] RepositoryFactory: Optional constructor parameters has been moved into RepositoryFactoryConfig interface (optional).
• [BREAKING CHANGE] Added websocketInjected (optional) parameter to the RepositoryFactoryConfig interface. RepositoryFactory.createListener() can now take injected websocket instance to create Listener object.
• [BREAKING CHANGE] Added websocketUrl (optional) parameter to the RepositoryFactoryConfig interface. it allows custom websocket url to be used to create the Listener object. By default (not provided), the factory will use rest-gateway url with '/ws' suffix appended (e.g. http://localhost:3000/ws)
• [BREAKING CHANGE] Listener.newBlock channel is now returning new object NewBlock rather than sharing with BlockInfo used by rest-gateway payload.
• Added stateHashSubCacheMerkleRoots to BlockInfo.
