Torch has an auto-update function that keeps the browser updated to the latest version. Additionally, you can always download Torch's latest version directly from Torch's Homepage.
Why should you always update Torch?
The Torch features work with many different media sources. When those sources make changes to their media, Torch needs to adjust it's settings as well in order to insure compatibility. Not updating Torch may cause un-expected behavior, and in order to troubleshoot any issue successfully, the Torch helpdesk will need for you to first make sure that you are in fact working with a current version of Torch Browser.
