When I install a new Ionic beta version, what about the projects I have made already? Are there not files in those folders that are from the previous version still?
The files are in the lib/Ionic folder by default when using the command line to make a project. When a new version comes out simply download the latest build and copy the ‘js’, ‘css’, ‘fonts’ files to the lib/ionic folder from the root of your project and you will be good to go.
