Autoptimize 2.7 is in the final stages and the beta version can as of now be downloaded from https://downloads.wordpress.org/plugin/autoptimize.zip
Main new features:
- the “critical CSS power-up” is now fully integrated. If you have the power-up installed and active already that takes priority, disable the power-up to use the integrated version.
- an experimental option to provide “fallback autoptimized CSS and JS”; in some cases a cached version of the HTML links to autoptimized CSS/ JS that was already removed. if you enable that option, Autoptimize will try to intercept those requests and redirect them to fallback versions to limit the breakage. the option is default off for now, but might become default on at a later stage.
- misc. bugfixes and improvements, see the github commit log for more info.
So who want to test? Feedback in the comments please! :-)
