+### 6.4 deprecations
+
+#### Deprecated --static-dir CLI flag
+
+In 6.4 we've replaced the `--static-dir` CLI flag with the the `staticDirs` field in `.storybook/main.js`. Note that the CLI directories are relative to the current working directory, whereas the `staticDirs` are relative to the location of `main.js`.
+
+Before:
+
+```sh
+start-storybook --static-dir ./public,./static,./foo/assets:/assets
+```
+
+After:
+
+```js
+// .storybook/main.js
+module.exports = {
+  staticDirs: ['../public', '../static', { from: '../foo/assets', to: '/assets' }],
+};
+```
+
+The `--static-dir` flag has been deprecated and will be removed in Storybook 7.0.
