------------------------------------------------------------------------------------------------
1.0             1. first release of demo program.

1.1             1. add impedance real/imaginary part, current density display.

1.2             1. add software version display.

1.3             1. sweep data log to file.

1.4             1. program crash caused by nyqust graph.

1.5             1. fix bug: program crash caused by nyqust graph.
                2. cursor operation will not work when sweep in operation NOW.
                
1.6             1. sweep operation can be repeated by REP button.

1.7             1. phase format can be +-180, or +360.
                2. input auto zero.(not prove to be functional)
                
1.8             1. AC value is selectable to be RMS or peak-to-peak.
                   notes: firmware version should be 1.08.
                   
1.9a            1. try to solve program crash on some PC.

2.0             1. fix bug of program crash which happen on PC with CVI run-time engine 
                   version 7.0.
                   
2.1             1. frequency allow to start from 0.1Hz.

2.2             1. bug fix: DC offset may drift after sweep. 

2.3             1. change program name.

2.4             1. log sweep start from 0.1Hz with steps of 0.1, 0.2, 0.3, ... 0.8, 0.9.
                2. sample cycle support auto mode which will automatically decide sample cycle.
                   the rule of sample cycle.
                   if freq < 1.0, then sample cycle is 10 seconds.
                   if freq < 10.0, then sample cycle is 1 second.
                   if freq >= 10.0, then sample cycle is 0.1 second.
                3. fix bug of EOS(CR, and NULL)

2.5             1. change OEM message from ATI. to ARI..

                2. add X,Y axis direction change feature for all graphs.
                3. Nyqust graph add "circuit mode" control.
                4. meter panel support new meter values.
                   1. real-imaginary meter has "circuit mode" selectable control.
                   2. capacitance or inductance value selectable control.
                   3. quality factor or dissipation factor selectable control.

2.7             1. frequency sweep from high to low.
                2. DC/AC sweep profile.
                3. Nyqust & bode with multiple lines capability.
                4. Bode graph selectable Z, Xs, Xp, Rs, Rp,...
                
2.8             1. bug fix for some communication interface function.
