-#### Deprecated scoped blocks imports
-
-In 6.3, we changed doc block imports from `@storybook/addon-docs/blocks` to `@storybook/addon-docs`. This makes it possible for bundlers to automatically choose the ESM or CJS version of the library depending on the context.
-
-To update your code, you should be able to global replace `@storybook/addon-docs/blocks` with `@storybook/addon-docs`. Example:
-
-```js
-// before
-import { Meta, Story } from '@storybook/addon-docs/blocks';
-
-// after
-import { Meta, Story } from '@storybook/addon-docs';
-```

-If you were using `argType.defaultValue` to fix issues with the above inference, it should no longer be necessary, you can remove that code. If you were using it to set a default value for an arg, there is a simpler way; simply set a value for the arg at the component level:
