2.0.0.rc.1

We have done quite some changes and improvements since the last version.
Mainly we have changes in the UI, as we have now replaced @tailwindcss/ui with the new TailwindCSS 2.x
We have many more plans for the UI and UX improvements in future releases, but we are eager to get 2.0.0 out
Aside from UI, we have also updated the Django framework to the latest Django 3.2.x LTS
