- Extension method smppPdu.GetMessageText(EncodingMapper) as replacement for MessageText property in a PDU class.
(ushort tag) method for registering custom TLV parameter type for any tag value. It helps to represent some complex parameters as structured objects. Example: var parameter = pdu.Parameters.Of ();
- MessageText property in PDU classes is obsolete. Use the function client.EncodingMapper.GetMessageText(pdu) or pdu.GetMessageText(client.EncodingMapper) to get th message text contained in the PDU.
[2.6.3] - 2019-03-04

- Replaced methods AddMessagePayload, AddSARReferenceNumber, AddSARSequenceNumber, AddSARTotalSegments and AddMoreMessagesToSend with corresponding classes in Inetlab.SMPP.Parameters namespace.
- Renamed the property "Optional" to "Parameters" in PDU classes. (backwards-compatible)

- PDU reader and writer
- split text on concatenation parts
[2.3.0] - 2018-03-18
- SmppClientBase.SendQueueLimit limits the number of sending SMPP messages to remote side. Delays further SMPP requests when limit is exceeded.
- SmppServerClient.ReceiveQueueLimit replaced with SmppClientBase.ReceivedRequestQueueLimit
- improved: processing of connect and disconnect.
[2.2.0] - 2018-02-01
- better processing of request and response PDU
- Flow Control. SmppServerClient.ReceiveQueueLimit defines allowed number of SMPP requests in receive queue. If receive queueu is full, library stops receive from network buffer and waits until queue has a place again. It is better alternative for ESME_RMSGQFUL response status. ### Fixed
- MessageComposer raises evFullMessageReceived sometimes two times by processing concatenated message with two parts.
[2.1.2] - 2017-12-11
