2018 is end of life and 2019 will be released soon. Autoptimize 2.5 is not at that point yet, but I just pushed a version to GitHub which adds image lazy loading to Autoptimize;
The actual lazy-loading is implemented by the integrated lazysizes JS lazy loader which has a lot of options some of which I will experiment with and bring to Autoptimize to the default improve user experience.
If you want you can download the beta (2.5.0-beta2) now from Github (disable 2.4.4 before activating the beta) and start using the new functionality immediately. And if you have feedback; shoot, I’ll be happy to take your remarks with me to bring AO 2.5 ready for release (I’m targeting March, but we’ll see).
We’re finalizing work on Autoptimize 2.4 with beta-3, which was just released. There are misc. changes under the hood, but the main functional change is the inclusion of image optimization!
This feature uses Shortpixel’s smart image optimization proxy, where requests for images are routed through their URL and automagically optimized. As the image proxy is hosted on one of the best preforming CDN’s with truly global presence obviously using HTTP/2 for parallelized requests, as the parameters are not in a query-string but are part of the URL and as behind the scenes the same superb image optimization logic is used that can also be found in the existing Shortpixel plugin, you can expect great results from just ticking that “optimize image” checkbox on the “Extra” tab :-)
Image optimization will be completely free during the 2.4 Beta-period. After the official 2.4 release this will remain free up until a still to be defined threshold per domain, after which additional service can be purchased at Shortpixel’s.
If you’re already running AO 2.4 beta-2, you’ll be prompted to upgrade. And if you’d like to join the beta to test image optimization, you can download the zip-file here. The only thing I ask in return is feedback (bugs, praise, yay’s, meh’s, …) ;-)
new: Autoptimize “listens” to page caches being cleared, upon which it purges it’s own cache as well. Support depends on known action hooks firing by the page cache, supported by Hyper Cache, WP Rocket, W3 Total Cache, KeyCDN Cache Enabler, support confirmed coming in WP Fastest Cache and Comet Cache.
new: Google Fonts can now be “aggregated & preloaded”, this uses CSS which is loaded non render-blocking
improvement: “remove all Google Fonts” is now more careful (avoiding removing entire CSS
We’re still looking for beta-testers and some of these new features might convince you to jump on board? You can download the zip-file here, installing it a simple one-time process:
Deactivate Autoptimize 2.3.x
Go to Plugins -> New -> Upload
Select the downloaded zipfile and upload
Go to Settings -> Autoptimize to review some of the new settings
TL;DR Autoptimize 2.4 will be a major change. Tomaš Trkulja (aka zytzagoo) has cleaned up and modernized the code significantly, making it easier to read and maintain, switched to the latest and greatest minifiers and added automated testing. And as if that isn’t enough we’re also adding new optimization options! The downside: we will be dropping support for PHP < 5.3 and for the “legacy minifiers”. AO 2.4 will first be made available as a separate “Autoptimize Beta” plugin on wordpress.org via GitHub and will see more releases/ iterations with new options/ optimizations there before being promoted to the official “Autoptimize”.
dropping support for PHP below 5.3 (you really should be on PHP 7.x, it is way faster)
dropping support for the legacy minifiers
These improvements will be released in a separate “Autoptimize Beta” plugin soon (albeit not on wordpress.org as “beta”-plugins are not allowed). You can already download from GitHub here. We will start adding additional optimization options there, releasing at a higher pace. The goal is to create a healthy Beta-user pool allowing us to move code from AO Beta to AO proper with more confidence. So what new optimization options would you like to see added to Autoptimize 2.4 and beyond? :-)
[corrected 19/02; wordpress.org does not allow beta-plugins]
So work on Autoptimize 2.2 is almost finished and I need your help testing this version before releasing (targeting May, but that depends on you!). The more people I have testing, the faster I might be able to push this thing out and there’s a lot to look forward to;
New option: enable/ disable AO for logged in users for all you pagebuilders out there
New option: enable/ disable AO for cart/ checkout pages of WooCommerce, Easy Digital Downloads & WP eCommerce
New minification/ caching system, significantly speeding up your site for non-cached pages (previously part of a power-up)
Additional support for HTTP/2 setups (no GUI, you might need to have a look at the API to see/ use all possibilities)
Important improvements to the logic of which JS/ CSS can be optimized (getPath function) increasing reliability of the aggregation process
Updated to a newer version of the CSS Minification component (albeit not the 3.x one, which seems a tad too fresh and which would require me to drop support for PHP 5.2 which will come but just not yet)
API: Lots of extra filters, making AO (even) more flexible.
