The first beta release of mod_pagespeed 1.11 is now available. This
release targets users on mobile devices and low-bandwidth networks by
adding Save-Data support. Save-Data is a new Client Hint that allows
site visitors to indicate that they would prefer lower-quality
resources in order to save data. [1] Sites are most likely to see
requests to save data today from visitors who have turned on Data
Saver mode in Chrome [2] or the equivalents in Opera and Yandex
Browser, often because they're on slow or expensive connections. Now,
with 1.11, when such a user comes to your site asking it to save data,
mod_pagespeed will compress images to a lower quality level [3] than
it would typically, decreasing their size further at the cost of
slightly more image distortion.
