initial release  september    01   2001

 new release       november  27   2001      better user interface ; more tools   user friendly   it will install over any existing issue  the install is the same as the old version

 new release      december   11   2001      

• added the save possibility with the "add to common log" button it will create a text file containing the data of the current page in clear language it will also save it on a big commonlog.txt file containing all the previously saved files
• added the possibility to print the screen (landscape format) there is also the possibility to edit the text files and print them with any text editor
• added    the "save as"      possibility at the main window it will create a text file containing the data of all the previously saved files this is the same file as the commonlog.txt but with an other name this way it will not be erased by the add to commonlog function . This permit an easy  comparison between project example :  cessna152longrange.txt   and  cessna152std_tank.txt

 new release      january   10   2002   (major release use all windows features)      

• improved the save possibility with the "save menu" it will create a text file containing the data of the current page in clear language  ; it will also save it on a airplane_name.dat file used by the software  ; and there is still the txt file with the airplane name
• added the open file menu it will only see and display the relevant *.dat files
• added a file information windows where it is possible to write in plain language a few comment on the current project . It is also saved with the other files
• added the possibility to open numerous airplanes at the same time
• added the windows title + airplane name on top in order to avoid mixing up files at saving
• added flight envelope at various scales

• now when the software is closed it will remember the last saved data "add to common log" and will present them at the opening without the need to re load the aircraft this can be checked by looking at title + airplane name on top of the the window .

 new release      january   13   2002 (minor release)     

• added the delete file menu it will only see , display  and delete the relevant *.dat  and *.txt files it will not delete the individual and common log txt files that can be useful and are re created on each "add to common log"

Beta release February    28   2002

• added the airfoil  design file menu it permit to edit and modify airfoil in order to pass it to other software such as X foil or panel for windows . It display  the airfoil to work on . It show small diagram of the foil before opening them . There is the possibility to save some info in one line of text in the airfoil dat file (first line) .
  1. The airfoil can be scaled globally in the Y axis (thickness).
  2. The airfoil can be modified by moving the vertex individually  in the Y axis (thickness)
  3. The airfoil can be modified by moving the vertex by group  in the Y axis (thickness)
• added a copy of airfoil data from uiuc under gnu licence plus other airfoils to a total total of more than 1100 airfoils
• corrected a bug in the jet section of the code of the "compute initial design" menu
• added colors to the flight envelope section
• corrected some of the example files

Beta local computer march 18  2002

• added faster drawing airfoil icon to the open foil section (the selected airfoil is displayed)
• added fast drawing polar icon to the open foil section (the selected airfoil polar is displayed if available it should have the same name as the airfoil but with a   ".pol"  ending  :(xxxxx.pol) )  . If no polar is available it will draw a straight line
• added  prototype pressure colors to the open foil section not finished yet

Beta and base release debugged  march 20  2002

• erased a new call to a function that got here by error this function didn't exist  any more on the beta and current release and this was blocking normal execution  it was a call to a symantec function despite that it is compiled with sun compiler ...  I just zapped it !
• on this day the current release and the beta release are the same .

Beta local computer april 05 2002

• added export to panel for windows function in order to run a 3D panel wing check  when finalized .
• added export to ray tracer function in order to make the pov file needed for rendering not finished yet
• progressed in prototype pressure colors to the open foil section still not finished yet

Beta release june 06 2002

• made new functions to  export to panel for windows .
• now the export to ray tracer function can make the pov file for the wing , horizontal tail , and vertical tail
• added the singularity function it permit to have an idea of what are the source the sink and the vortex. Those are the building block of the aerodynamic and of the panel method . It permit to "play"   with a source ;  a sink ;    and a vortex and to grab the feel of how they behave when associated together  with a free stream creating a rankine oval  or a circle (cylinder) or circle with circulation (rotating cylinder).   This is not needed for airplane design but help to understand how things works
• finished the pressure colors coding but not released because it need a pressure computation method (panel method)
• begined to study a panel method 2d and 3d
• corrected a bug : added the file : def.dat.pol in the foil directory . it permit do draw the foil preview with default (straight) polar when none are available
