iOS 27.3 Adds Vertical Tabs, Adaptive Dark Mode to Safari

Apple is adding vertical tabs and an Adaptive Dark Mode to Safari with iOS 27.3, iPadOS 27.3 and macOS Golden Gate 27.3.

[...] Apple is adding Adaptive Dark Mode for websites that don't have a dark mode design option by default. If you use Dark Mode and then browse to a website with a bright background color, Safari will offer an option to "Try" Adaptive Dark Mode. After tapping Try, Safari renders a Dark Mode version of the page that makes the background darker, changes text contrast, inverts logos and graphics, recolors vector artwork, lifts raised surfaces, and rebalances layered shadows. Each website will be adapted based on what's needed to make it readable, so not every tweak is applied to every site. You can opt to turn Adaptive Dark Mode on for all sites or on a site-by-site basis after using it. If a site has a native dark mode or has a dark design already, Adaptive Dark Mode won't activate. Developers can also add a tag that causes Safari to ignore Adaptive Dark Mode and show the website as the developer intended.
