Hello! Version 7 is compatible with version 6.
Some notes about a migrating from AphaControls version 6 to version 7 :
1. Don't forget to backup own projects!
2. Load all forms in projects and resave them (datamodules must be resaved too if SkinManager is placed there)
3. If you have Delphi or Builder warnings about unexisting “GeneralData” property (after the project loading) – ignore it. GeneralData is a property of internal skin which is not used now.
4. It's strongly recommended to update all skins to latest versions (internal skins must be reloaded too). Old skins may work slow. If you have own skin then open him in the latest ASkinEditor, press the “Warnings” button and you will have information how the skin may be improved.
