If you are using Nokia Sports Tracker you may notice some changes in the web part of the service. Now it is possible to login to the page with your Nokia Account, common for services like Nokia Friend View, or Ovi. There are some changes in workout presentation. It is possible now to display separately graphs or speed vs. time and altitude vs. time. Using groups and community is now easier as well. Check the service and see what else new you can find in there.
Example workout is available here.
