• Fixed: 'Apply models' crashes the program in certain conditions.
• Other bug-fixes.

• New import module that performs order list import for inventory optimization.

• Minor GUI changes.
• Bug-fixes.

• Minor GUI changes.
• Bug-fixes.

• Minor GUI changes.
• Bug-fixes.

• Renewed Financial market module.
• Fixed: ODBC\OLEDB import problem.

• Preview for multiple files with the same extension and multiple sheets of XLS\XLSX.
• Now if a target variable does not vary, for example, all observations are zero, then GMDH Shell produces constant predictions instead of throwing an error message.

• New option in the 'Save as' dialog: save project without simulation results.
• Improved 'Welcome page'.
• Fixed: GS does not show simulation results immediately on processing completion.
• Fixed: Example projects are deployed to incorrect directory.

• GMDH Shell now uses project files with extension “.gsp”. You can double-click at .gsp file to open a project. When you open previously saved project including old .xml and .model projects, you should open the project file specifically, not a dataset like it was before.
