WebKit Features for Safari 26.4

March has a way of bringing a lot of new things to WebKit — and this year is no exception.

WebKit
The heart of this release is focused on what web developers ask for most. We hear you loud and clear. Results from 2025 developer surveys made it clear you want time to catch up with new features, not be swamped with more. You want existing features to work consistently across every browser. You asked for browser engineers working on WebKit to help you by squashing bugs and closing gaps in spec coverage. That’s what this release aims to do.

Congratulations, it is a really, really good idea.

The thing we web developers need most nowadays is stability and total compatibility between browsers. Nothing else is nearly as important.

There is no chance I am going to use any not fully cross-browser feature, unless I have no other option. It would make my work harder with no real advantage.

Even worse, here in Europe the demand for Safari compatibility is small, so there is no sense in using Safari only features. Safari users will much better served by these changes.
