IOS 27.3 AND MACOS 27.3 ADD VERTICAL TABS, ADAPTIVE DARK MODE, AND MORE TO SAFARI

Summary from the TLDR Design newsletter

Apple is introducing vertical tabs in Safari's developer betas across iPhone, iPad, and Mac, with tabs displayed as compact icons in a left sidebar that can expand to show website titles. A new Adaptive Dark Mode can automatically generate dark versions of websites that lack native support, either on demand or through a persistent preference. Siri AI can also organize, sort, move, and close tabs, with broader awareness of webpage content planned for a future update.
