Unfortunately, Startup is not a free to update for the first or second version of the Startup, just because Startup since version 3 is a new product with new design and code.
The main difference is the code is much simpler and more reliable than it was before. It’s much easier to edit the code now that it was before. It’s a completely new product built from scratch. Also, you get an unlimited amount of exports with an unlimited number of projects you can build on it. And we added one tiny, but time-saving feature – Preview, that shows you the website before you hit the Export. In the end, we’ve got an online-editor now that allows you to edit the content of any block without accesing to the source code. Currently, a dedicated team of developers and designers is working on the project.
