Fixed a bug in the Del_Link method where node connection deletion failed when source id and target id were swapped. && Added a Get_Socket_Str method to the base connector class, allowing external code to query the socket to determine whether a connection is allowed. && Added a boolean-type connector. && Input connectors can now be initialized to exclusive input mode, meaning that an input connector of this type allows only one input at a time, establishing a new connection will disconnect the existing one. && Added a message filter node that allows incoming messages to pass through when the input conditions are met.
