Starting from Chrome 101, the information available in the User-Agent string will be reduced. Sites that haven’t had time to migrate away from using the reduced User-Agent string can take part in a deprecation trial to continue receiving the full User-Agent string.
Chrome version number will soon go from two digits to three, which might affect any code that's parsing the User-Agent (UA) string. A feature flag available from Chrome 96 to 99 enables early testing by forcing the major version number in the UA string to 100.
Starting in Chrome 95 Beta, an origin trial allows sites to opt into receiving the reduced user agent string, which will contain only the browser's brand and significant version, its desktop or mobile distinction, and the platform it's running on.
