--------------------------------
2014-05-21

--------------------------------

2012-11-13

* New feature: Automatically reconnect to the database after communication problems.
  Previously a lost connection with the database was only re-established when the SIMCA-online service was restarted.
  This has been changed so that the database connection is closed on each error. Then on the next database call
  an attempt will be made to reopen the connection.
 
* Fixed a bug that prevented the truncation of the log file when it reached the Log File Size
  set in the configuration.

* Automatically increments build number on each build.

* Added digital signature to the built DLL.
