In addition to fixing a number of bugs, it also contains some new features, such as Type Ahead Find:
"Type Ahead Find is a new feature that allows quick navigation when you type a succession of characters in the browser, matching the text in one or more links on the page. To give it a spin just go to a web page, start typing, watch the typed characters highlight as they find a match in a link and hit enter to load the selected link. You can also use it to search for any text on the page by typing / before your search text."
