Did you know that AVIF (the AV1 Image File Format) was supported in all the major browsers (Firefox, Safari, Chrome/Edge)?
This has been the case for almost 2 years at this point.

A few years ago I started writing about evolving web standards and @rbyers.net suggested I should cover WPT: the web platform tests project that most people working with the web have a vague idea about that has evolved into an engine of interoperability. since then, I've been tracking people down
How a Shared Test Suite Fixed the Web’s Biggest Problems
The story of Web Platform Tests (WPT), the collaborative test suite that transformed the web from an inconsistent platform into a stable one.

Before, you needed a plugin to use Baseline semantics in your Browserslist queries. Now you don't!
Just give it a target like `baseline widely available` and it'll work out of the box

I know some people in the web community are concerned that Baseline will discourage devs from using new features—or anything not "Widely Available".
Personally, I'm not worried about that at all. If anything, I think Baseline will speed up new feature adoption!

🎉 Happy 30-month anniversary to Container Queries – in every browser since Feb, 2023. It was supposed to be impossible, but here we are!
Why 2.5 years? Nothing will change tomorrow, but Baseline uses this milestone to signal confidence a feature has gained "wide" support.

🚀 The #StateOfHTML 2025 survey is now open!
➡️ Take it now: survey.devographics.com/en-US/survey...
💡 Spending time to fill these out is an investment into your craft, as browsers are using the results to make prioritization decisions.
You don't have to do it in one sitting (or even one device).

I LOVE this …Chart of Shame on webstatus.dev/stats “Features missing in only one browser”.
Even lets you click on individual data points and see which features each browser is holding the Web back from!
Hopefully it will motivate implementations of these features!
