Legacy browser support

Recent versions of Unpoly supports all modern browsers.

The last version with support for Internet Explorer 11 is 2.7.

ES6 build

unpoly.js uses ES2020 that may not supported by (very) old browsers or build tools. If you're not already working around this with a transpiler like Babel, you may also use the ES6 build of Unpoly:

Development	Production
`unpoly.es6.js`	`unpoly.es6.min.js`	60.1 KB gzipped

The ES6 build does not contain any polyfills.
