+| WARNING: BETA RELEASE    |
+|--------------------------|
+
+Thank you for testing the beta release of org-gtd 3.0.0 .
+The API is stable unless big breakages are discovered for some reason.
+
+For a summary/dirty changelog, see a file called `changes-for-3.0.org' in the
+repository: `https://github.com/trevoke/org-gtd.el'.
+
+Important notices involve:
+- run `org-gtd-upgrade-v2-to-v3'
+- this moves all your habits to a new sub-heading in the default org-gtd file
+- it will create this file if you don't have it
+- as long you respect the Habits structure, move them where you want
+
+- some of the key commands have changed, e.g.
+- `org-gtd-choose' is now `org-gtd-organize'
+- `org-gtd-process-item-hooks' is now `org-gtd-organize-hooks'
+
+So do review this, and join the discord in the readme to discuss the changes!
