- Render engine was switched from Webkit to Blink on February 2nd, 2017.
- Image optimization library was switched to use the one in mod_pagespeed on December 12th, 2016.

The initial version of the API. This release includes support for localization in 40 languages.
On October 29, 2013, the
ruleScore field, which has been deprecated in PageSpeed Insights for over a year, was removed from the API. We recommend that clients use the
ruleImpact field instead.
