## 2.2.0 (2021-06-18)

This release includes support for a new `threshold` option [PR](https://github.com/GoogleChromeLabs/quicklink/pull/214) to allow users select the % of link areas that entered the viewport before prefetching. This can reduce the number of links to prefetch at a time, and ultimately reduce the impact on CDNs and servers. 

Thanks to [@verlock](https://github.com/verlok) from YNAP for this contribution.
