## What is Mithril?
A modern client-side Javascript framework for building Single Page Applications. It's small (<!-- size -->8.62 KB<!-- /size --> gzipped), fast and provides routing and XHR utilities out of the box.
A modern client-side Javascript framework for building Single Page Applications. It's small (<!-- size -->8.63 KB<!-- /size --> gzipped), fast and provides routing and XHR utilities out of the box.
Mithril is used by companies like Vimeo and Nike, and open source platforms like Lichess 👍.

### v1.1.7
- Promise polyfill implementation separated from polyfilling logic.
- `PromisePolyfill` is now available on the exported/global `m`.
---
### v1.1.6
- core: render() function can no longer prevent from changing `document.activeElement` in lifecycle hooks ([#1988](https://github.com/MithrilJS/mithril.js/pull/1988), [@purplecode](https://github.com/purplecode))
