    allowing cooperation with clients which support non-standard and legacy
    encoding standards (IA5, ISO 8859-1, HP Roman8 etc.) [#1118, customer
    request]

Changes

  - 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 (e9ce130) released on 20 March 2015

    relative from 2000-01-01 00:00:00. [#174]

3. Evaluation Version Limitations

If the product is installed without entering a valid serial number obtained
from producer then it is installed as Evaluation Version. It offers whole
functionality of a full version thus allowing to test all the procedures,
properties and events. THE ONLY LIMITATION IS THAT THE CONTENT (TEXT) OF THE
RANDOMLY CHOSEN SENT AND RECEIVED MESSAGES IS CHANGED.

To remove the limitation you should contact Tops and purchase the full licence
which will provide you with a valid serial number.

After obtaining the serial number the product HAS TO BE REINSTALLED with
entering the serial number in the appropriate form of the setup program. THERE
IS NO NEED TO UNINSTALL PREVIOUSLY INSTALLED EVALUATION VERSION.

Please see User Manual for the detailed information on product features and
usage.
