The new update brings two security upgrades that you can opt in to. First, the Enhanced Safe Browsing gives you protections from phishing, malware and other web-based threats. When enabled, Chrome checks whether pages and downloads are dangerous by sending information about them to Google Safe Browsing. If you are signed in to Chrome, then Chrome and other Google apps you use (Gmail, Drive, etc.) will further protect you based on a holistic view of threats you encounter on the web and attacks against your Google Account. Besides, there is a new Secure DNS, a feature designed to improve security and privacy while browsing the web. The Chrome's Secure DNS feature uses DNS-over-HTTPS, thereby helps prevent attackers from observing what sites you visit or sending you to phishing websites.
