Minor tweaks in compiled demo applications.
Minor fix in installation scripts.
Problem with multi-threading in calls to response functions. [#1121]
Time difference to UTC sometimes calculated incorrectly in SMPP Absolute Delivery Time and Validity Period. [#1103]
6.0.100 (r2428) released on 20 March 2015
Added C# and Visual Basic .NET source code examples for an Windows Service class application.
Added encoding and decoding of ussd_service_op and its_session_info TLVs (SMPP optional parameters) used in USSD mode of operation through ExtendedParameters methodology. [#1054]
ISO encodings (ISO-8859-[1, 5, 8]) determined incorrectly for some messages. [#1076]

ExtendedParameters exposed in demo application interface. [#804]
All relative times (Delivery Time and Validity Period) are now calculated relative from 2000-01-01 00:00:00. [#174]
Flags smpp.ascii-frontend and smpp.7bit-encoding separated for better control on decoding for some specific clients. [#936]
AddressRange is now passed through ExtendedParameters of OnSmppLoginReceived. [#885]
soReplaceIfPresent (SubmitOption) flag moved to ExtendedParameters for better clarity. [#869]
