Browsing through Chrome in the middle of the night on your iPhone will no longer burn your retinas. Version 78 of the browser now supports iOS 13's system-wide dark mode, which means if you have the feature enabled, Chrome will follow suit. However, Google's take on the dark theme isn't a real black background. Instead, it brings a grey background colour throughout the interface. Sites that support dark mode will change as well.
Another change this update brings is the new card-like interface for sections like Bookmarks, History, Recent Tabs, Reading Lists, and Settings. These sections will slide up from the bottom when you pull them up, and you can swipe them away when you're done with them. Chrome now also lets you add a new credit card directly from the Settings page. This update is now available on the App Store.
