==== 2007.08.31 (v 0.9.7.0831) ====
  * CHANGE: HW Analog values have even more flexible transformation settings. There are three phases now: linear transformation of the value from IO, interpolation curve, linear transformation of the result of the interpolation curve (ex.: temperature shift of Ni1000).

==== 2007.08.18 (v 0.9.7.0818) ====
  * CHANGE: B98 has got a new output "datetime" that can be used for DateTime variable type and its visualization in the touchscreen.

==== 2007.08.07 (v 0.9.7.0807) ====

==== 2007.05.17 (v 0.9.7.0517) ====
  * CHANGE: Improvement of PI controller
    * Bug fixed: Newly parameter Of influences only P-part. I-part integrates difference e = w - x where Of is not presented. For precise definition of P-part see documetation or graph below.
    * Parameter enable: If enable = false then y = disval (as before). Newly if enable is set to true, then y continuosusly (i.e. without jumps) changes to the new value given by P and I parts. 

==== 2007.05.04 (v 0.9.7.0504) ====
  * CHANGE: Minimal flash save interval set to 6 hours.

==== 2007.04.24 (v 0.9.7.0424) ====
  * CHANGE: P/PI/PID blocks have now a bit different behaviour:
    * If MIN is set to nonzero (for example 20) the P controller transfer function is tresholded at this value (20) which causes effectively "shift" of the function to the left i.e., breakpoint of the transfer function is no longer in value w+Of, but more to the left. See the picture below. New version of PID makes an automatic shift of the function to the left (PID reverse) for nonzero values of MIN.

==== 2007.01.25 (v 0.9.7.0125) ====
  * BUG-FIX: [#231] The name of the application in the Windows Firewall is correct (before, there was an empty entry). On older installations it is necessary to clear the ...**MUICache** keys in the registry in order to take the changes into account.
  * CHANGE: Block B108 Beep improvements.

==== 2007.01.12 (v 0.9.7.0112) ====

==== 2006.12.13 (v 0.9.6.1213) ====
  * BUG-FIX: [#119] Digital and analog outputs didn't handle bad communication value quality correctly.
  * NEW: Evaluation timeout. Configurable from Options/Performance settings in the WinForms RT. It specifies the maximal time between start of the communication and start of the evaluation. This allows that the HW variables are updated before the logic evaluation takes place. Also accessible directly in the soft_plc.config as PERF_EVAL_STARTUP_TIMEOUT item.

==== 2006.11.28 (v 0.9.6.1128) ====
  * BUG-FIX: [#34] The format of the project file wasn't checked. The runtime accepted unknown formats and behaved like if it were an empty project.

==== 2006.07.17 release version 0.4.6.717 ====
  * fixed Bug0002 (T16 to T19 badly save their internal parameters.)

==== 2006.07.14 ====
  * fixed Bug0001 (B107 and T14 badly save their internal parameters. The project can't be opened in RT afterwards)
