 Since early versions, Storybook shipped with a `setAddon` API, which allows you to extend `storiesOf` with arbitrary code. We've removed this from all core addons long ago and recommend writing stories in [Component Story Format](https://medium.com/storybookjs/component-story-format-66f4c32366df) rather than using the internal Storybook API.
 
+#### Deprecated disabled parameter
+
+Starting in 6.0.17, we've renamed the `disabled` parameter to `disable` to resolve an inconsistency where `disabled` had been used to hide the addon panel, whereas `disable` had been used to disable an addon's execution. Since `disable` was much more widespread in the code, we standardized on that.
+
+So, for example:
+
+```
+Story.parameters = { actions: { disabled: true } }
+```
+
+Should be rewritten as:
+
+```
+Story.parameters = { actions: { disable: true } }
+```
