Mastodon due to the decentralized nature can result in a significant extra load on your site if someone posts a link to it. Every Mastodon instance where the post is seen (which can be 1 but also 100 or 1000 or …) will request not only the page and sub-sequentially the oEmbed json object to be able to show a preview in Mastodon. The page requests should not an issue as you surely have page caching, but the oEmbed object lives behind /wp-json/ and as such is not cached by page caches. The solution; the WP Rest Cache plugin and one small code snippet (for now). A lot more info can be found in Donncha’s excellent post on the subject.

2020: the year Flash was finally buried
10 years after it became irrelevant (one of the first blogposts I wrote that generated discussions & traffic), Flash is now officially buried;

Fixed: WordPress 5.6 required Autoptimize settings change
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 🙂
Question for you: what are Open Source’s values?
So open so(u)rcerers; what in your opinion are the core values you think are essential for the success of the open source ecosystem (be it WordPress or other)?
Autoptimize 2.7.7 fixes 2 security issues, please upgrade.
Autoptimize 2.7.7, which was release earlier today, has misc. improvements, but more importantly comes with 2 security fixes (one XSS, one malicious file upload, both for authenticated users), so please upgrade sooner rather then later.
Don’t take free & open source for granted; donate to Mozilla!
Do you ❤️ the free and open web and do you want to ensure a non-profit can continue to play an important role? Do you use Firefox or use MDN (Mozilla Developer Network) to check up on JS or CSS or HTML syntax?
We do too and as from today Optimizing Matters will donate $20 monthly. If you use Autoptimize or Async JavaScript or WP YouTube Lyte then please, pretty please, consider donating at https://donate.mozilla.org too.

Autoptimize code; blacklist/whitelist becoming blocklist/ allowlist
As of the soon-to-be-released Autoptimize 2.7.4, all occurrences of “blacklist” and “whitelist” in the code will be changed into “blocklist” and “allowlist”. There is no impact for users of Autoptimize, everything will work as before.
If however you are using Autoptimize’s API, there are two (to my knowledge rarely used) filters that are now deprecated and will be removed at a later stage. `autoptimize_filter_js_whitelist` and `autoptimize_filter_css_whitelist` still work in 2.7.4 but if you’re using them switch to `autoptimize_filter_js_allowlist` and `autoptimize_filter_css_allowlist` to avoid problems when they are removed in the release after 2.7.4.
Small post-publishing clarification dd. 22/07/2020: this post is just an announcement, I feel no urge to discuss the change and am not really interested in arguments pro or contra. Don’t fret over this change, fretting is useless, instead enjoy the summer, kiss your lover, read a good book, … 🙂
