The old Toolbox is the coding tool, which is really nice and helpful and will still exist, so don't worry.
Manus has now made Toolbox 2.0, which despite the name, is not that similar to the old Toolbox. It is a modelling program, sort of like Techne, but with a built in shape editor, templates and coding already in it. He has decided he will charge money for that, and that's okay. The old toolbox remains free.
Manus, i have a question. Do the old Toolbox 2 releases stay free?
