close #1436 BREAKING CHANGE: When building a js/ts entry file with --target lib, the library now exposes a Module with both default and named exports. This means in the UMD build, the default export now needs to be accessed as `window.yourLib.default`, and in the CommonJS build as `const yourLib = require('yourLib').default`. If you don't have named exports and want to retain the previous behavior, you can configure webpack to use `output.libraryExport: 'default'` in `vue.config.js`.
