This is one of the larger groups of bug fixes that Google has included in recent releases of Chrome. The company has been using a rolling update schedule for Chrome, and it often will release new stable versions of the browser with just a few bug fixes or security patches. But this release is a fairly major one.
The full list of fixes in version 16.0.912.63 of Chrome:

Also in this version of Chrome, Google added the ability for people to add new users to each installation of the browser. Each individual user can sign in to Chrome and sync their settings, extensions and other add-ons to the Web, giving each person a separate experience.
“Keep in mind that adding new users to Chrome isn’t intended to secure your data against other people using your computer, since it just takes a few clicks to switch between users. We’re providing this functionality as a quick and simple user interface convenience for people who are already sharing Chrome on the same computer today,” Google’s Tim Steele wrote in a blog post.
