If you’re a Chrome user on macOS, then you’ll definitely want to update the browser ASAP. This is because according to a report from Google, the update contains a fix for a high-severity zero-day bug that had somehow made it into the stable release without anyone noticing, at least until now.
The details of the bug’s workings should eventually be revealed, but only after a majority of users have updated their browser and are protected from it. However, Google says that those details could still be restricted if it is later discovered that the same bug exists in third-party libraries that other projects rely on.
In any case, keeping your browser updated especially in terms of security and bug fixes is a good thing, so if you haven’t updated your browser yet, now might be a really good time to do so.
