Release Notes

Added
- MMS m-notification-ind and m-delivery-ind over SMPP
- WorkersTaskScheduler class creates worker threads to handle received requests for a client.
- ReceiveTaskScheduler property in SmppClientBase class. Received requests can be handled in individual or global TaskScheduller or in standard TaskScheduler.Default.
 By default client uses WorkersTaskScheduler with 3 worker threads.
- RetryUntilConnectedAsync extension method for SmppClient class that helps to establish connection when a SMPP server is temporary unreachable.
- SubmitBatchAndWaitForDeliveryAsync extension method for SmppClient class that helps to submit a batch of SubmitSm PDUs and receive all delivery receipts.
- SubmitWithRepeatAsync extension method that help to repeat the SubmitSm requests on disconnection or unsuccess reponse status.

Changed
- Target Framework changed from .NET 4.5.2 to .NET 4.6.1
- SmppClientBase.SendQueueLimit limits a number of requests waiting for response. When this limit is exceeded, SubmitAsync method is blocked until queue has a free slot.
- Less GC pressure by reusing reading buffer.
- Improve DeliverReceipt deserialization when received PDU has wrong DataCoding.
- Deliver receipt serializer enriches DeliverSm PDU with optional parameters (MessageState, ReceiptedMessageId, NetworkErrorCode) only when PDU was not received from remote side.
- Throws GenericNackSmppException when GENERICK_NACK response received in Submit methods.
- Throws ObjectDisposedException when trying to call public method on disposed classes SmppClientBase, SmppClient, SmppServerClient
- New implementation of SMPP connection that frees all used resources after disconnect.
- Improved batch submit. Send several PDUs in one TCP packet.

Fixed
- ArgumentNullException in MessageComposer by adding a PDU with empty text
- SmppClientBase.SendSpeedLimit sends more than allowed PDUs when run SubmitAsync in tasks.
- GSMEncoding returns wrong number of bytes for Turkish charset when both NationalLanguageLockingShift and NationalLanguageSingleShift are specified.
- Text splitting. The maximum length of the short_message field is not used if NationalLanguageSingleShift is enabled.

Removed
- evConnected event from SmppClientBase class. SmppClient is connected after call of the method ConnectAsync or on the event evRecoverySucceeded. SmppServer has own method evClientConnected.
- Obsolete properties from PDU classes.
- QueueState class and SmppClientBase.Queue property. Use SmppClientBase.Metrics instead.
- SmppClientBase.WorkerThreads property. Set the SmppClientBase.ReceiveTaskScheduler property to the instance new WorkersTaskScheduler(3).
