An update for the Android Market has just been released by Google. It doesn't bring any big visual changes, mostly under the hood stuff. It now gives you the ability to auto-update all apps rather than having to manually set this option for each of them. You can also set the market to update apps only via WiFi and not cellular network to cut costs. Another new feature is to setup a homescreen shortcut for any newly downloaded app; this is also present in Honeycomb. As for visual changes, the font is slightly smaller, you can now do voice search and the app drawer icon has changed somewhat.
