OFF-Anki Importing
You can directly upgrade to this version without extra operation.
However, several new Anki Note Types will be created, to name a few, DBasic DChoices GDBasic and so on.
They are created to avoid name collision with the previous types.
The key feature added in v2.0.0 is Genanki Integration, which allows you to create apkg files without opening Anki.
