List of things I had to fix after update to 2.0.2. Hope this helps.

1. Unpublish the Offcanvas Module otherwise off canvas menu will only display the menu root items.
2. To get the Offcanvas menu to display, I had to select a predefined offcanvas menu layout from the template options menu.
3. Many CSS elements have changed, I had to make quite a few changes to my custom.css files, particularly where I've used custom styling for the off canvas menu.
4. Re-enable font awesome in the template options menu.
5. Some, not all, FA icons have changed names.
6. Re-enable Google Fonts in the template options
7. When re-adding the Google Font API key in the template options, I needed to click the save button on the top RHS of the screen before clicking update, otherwise there was a error message.
