Using the Automatic Updater
To perform the automatic upgrade through webJobs, click on Upgrade Now in the NOTICE box.
The software will then bring up a list of files that have been modified. Make sure to review this list carefully, and back up any files that you've modified on this list. The update will overwrite them.
Scroll down to the bottom of the page, and click Yes to overwrite all of the files. Wait for the software to tell you that the update is completed. Do not close or reload the browser during this upgrade period!
