Quick public service announcement; Autoptimize 2.9 is almost ready to be released but given the planned release of WordPress 5.8 (July 20th) and the risk of support requests mixing up WordPress core update related issues with the Autoptimize update related issues, Autoptimize 2.9 will probably be released one week after WordPress 5.8, so on or around Tuesday 27th.
If you’re eager to use 2.9 (with better image optimization, improved JS optimization and per page/ post Autoptimize settings) you can off course download the beta here immediately.
