Updates can occur for many reasons: new features being added, fixing bugs, or, most importantly, patching security flaws.

It paid to keep an eye on updates and install them promptly — Flash and Reader weren’t going to update themselves, after all. Chrome updates itself in the background, so you don’t have to worry about having the latest version.
