Hello,
You can update your software using MyStandard portal (button "MyStandard" in the top right corner of this page).
You can login to MyStandard with your StandardID (your email address that you use for logging in to your software).
After logging in you should see your company in the left side pane. When the company is selected, you can select the button "Update Version".
In the bottom you will see Release Version and Test Version (if there is a test version at the time). I would always suggest to update to Release Version.
Best regards,
