@OurFreeSociety,
We announce every time the browser updates here on Community, Reddit and our brave.com/latest page. Be on the lookout for Release notes posts.
Apologies for the frustration but this is generally not a regular occurrence (browser not updating properly) but does happen and can sometimes be hard to diagnose the exact cause of as many times it’s something on the user end that may be specific to them/their setup. This is why we advise re-running the installer because it almost always works and the issue tends to fix itself by the time the next update releases.
