WWDC26: What’s new in WebKit for Safari 27 | Apple
Safari 27 beta adds 60+ new WebKit features with a year focused on improving existing web platform quality.
“We put our focus there this year rather than on implementing a whole lot of brand new ones.”
Apple's WWDC26 WebKit session announced Safari 27 with 60+ new features (customizable select, CSS grid lanes, model element) and a focus on compatibility and quality over new feature volume. This is a web browser engineering update with no meaningful AI industry signal.
