Some people asked for documentation/ information on that new autoptimize_filter_imgopt_lazyload_from_nth filter which allows one to tell AO not to optimize the first X images found in the HTML, so here is an example code snippet that sees AO not lazyload the first 5 images:
PSA: WordPress 5.6 changes the filename of jQuery core. If you’re using Autoptimize and you have jQuery excluded (which is default) you will want to update your JS optimization exclusion list from js/jquery/jquery.js to js/jquery/jquery.min.js.
Update: Autoptimize 2.8 will automagically fix this, urgently looking for some testers to download https://github.com/futtta/autoptimize/archive/beta.zip (make sure 2.7.8 is disabled when enabling the beta). If all goes well and I get some confirmation the update (which has a lot more then just the fix) will go out today!
Update2: AO28 was released, all is (or should be) OK now :)
Obviously if you have page caching (which you should) this can have an impact as well, as a cached page will not result in LYTE “seeing” the request, so the cached YouTube data would not get refreshed even if older then 2 months. Then again having such aggressive page caching would likely cause other issues (nonces in forms becoming invalid and such), so I *think* the one month margin (results cached for 2 months whereas Google wants activity in 90 days) should suffice.
For those who don’t like the cache to expiry of if you want more or less then 2 months; I added 2 filters allowing you to tweak with a bit of code. Returning false to lyte_ytapi_check_cache will make LYTE function as before (no cache expiry) and the cache expiry threshold can be changed using the lyte_ytapi_cache_gracetime filter.
And like blogposts concerning LYTE, here’s a video to show it action: Yves Tumor with “Gospel for a New Century”. Weird stuff I admit (you have been warned), but good weird really …

You probably have heard about AVIF already, but if not; it is a new image format which is based on the AV1 video format and generally has superior compression than the better-known WebP, JPEG, PNG and GIF formats. Avif is currently supported by Chrome & Opera and can be enabled by setting the image.avif.enabled flag in Firefox.
So there you have it, AVIF is now available in WordPress!
So AVIF is a new(ish) image format that promises even better optimization then WebP and is supported in desktop Chrome & behind a preference in Firefox; go to about:config and set image.avif.enabled to true.
If you are using Autoptimize to optimize your images and you want to test AVIF images, you can use below code snippet to do so;
