•Changed the handling of reading exceptions.

•Reject message was being handled as ConfirmedError in some cases.

•Fixed errors when handling lists.

•Handling invalid real numbers (QNAN).

•Fixed the verification of connection status.

•Fixed the information about the execution status of a command.

•Additional options to search for COMTRADE files.

•Propagating IOKit events.

•Fixed the collecting of oscillography for Areva and Alstom relays.

•Support for Double data types in mms_float.

•DNSNames with port specification in IED's IP address.

•Fixed the ICD Sel import process, additional protection to avoid writings and polling during a reconnection.

•Fixed a memory leak (VLD).

•Fixed a memory leak when disconnected (COTP) and test of SEL semaphore.

•Log of timezone when starting this Driver.

•Considers TimeZone Unknown as valid for local offset calculation.

•Changed the re-enabling mode of Reports after a reconnection.

•LDs cannot be created anymore, except when reading LD files or after executing a GetServerDirectory command (Case 11378).

•Removed zeroes to the left of IP addresses (Case 11379).

•Removing zeroes to the left did not consider using the port after the IP address.

•Reprogrammed Reports completely after a reconnection.

•Improved performance of status Tags.

•A request for TCP/IP disconnection was not performed when an MMS::Status request failed or did not cover all situations.
