Version 1.0 was stopped at the end of December because it probably did not meet the requirements of the developers. A release candidate was then made from this. According to Vue.js creator Evan You, the plug-in architecture was far less modular than planned, some Vue specifics were built-in (instead of modular) and there was probably a lack of selectivity for numerous interfaces. You and his team continued to work on the now released Vite.js 2.0. For this purpose, the Vite team revised the plug-in API so that it could remove or outsource some more specific functionalities. The configuration is also more clearly separated into build and development server, the performance is considered to be improved and various minor problems have been fixed.
