We have several pages with good Pageseed-values - even those with 100/100. Since a few days however, Pagespeed claims across all sites (technically different, different servers) that our images could be more optimized.Does anyone know what exactly has been changed by the algorithm? On the one with PS 100/100 (before), we use jpegoptim, so we really don't know how to optimize further.Images are uploaded by our application and then optimized.Any insight would be appreciated. Is there a changelog for PS anywhere?
