Google has released Chrome 73 for Windows, macOS, and Linux. The latest version of the popular browser introduces a number of new improvements, including the much-awaited Dark Mode, which is currently only available for macOS. The release notes promise that the “Windows support is on the way.”

While Chrome Dark Mode has been in the news for the past couple of months, the release of Chrome 73 makes things official. Now, when you are using the Dark theme on your operating system, the browser will match the theme automatically.
