Apple has released Safari Technology Preview 235, continuing its tradition of providing developers and users with early access to experimental browser features. This latest update brings a collection of bug fixes and performance improvements across multiple web standards, maintaining Apple’s commitment to advancing Safari’s capabilities before features reach the stable release channel.
What Safari Technology Preview Offers
