A new version of Google’s Chrome web browser includes fixes for at least twenty-one security issues.

According to the announcement, Chrome 54 “contains a number of fixes and improvements”, but it doesn’t mention any specifics. If you want to know exactly what’s different, you’ll have to risk crashing your web browser and look at the full change log, which lists at least 10,000 changes.

For most users, Chrome will update itself over the next few days. You can usually trigger an update by running Chrome and navigating to the Help > About page (click the ‘three dots’ icon at the top right).
