 ### Core changes
 
+#### Dropping support for Node.js 16
+
+In Storybook 8, we have dropped Node.js 16 support since it reached end-of-life on 2023-09-11. Storybook 8 supports Node.js 18 and above.
+
 #### Autotitle breaking fixes
 
 In Storybook 7, the file name `path/to/foo.bar.stories.js` would result in the [autotitle](https://storybook.js.org/docs/react/configure/overview#configure-story-loading) `path/to/foo`. In 8.0, this has been changed to generate `path/to/foo.bar`. We consider this a bugfix but it is also a breaking change if you depended on the old behavior. To get the old titles, you can manually specify the desired title in the default export of your story file. For example:

+#### Removed postinstall
+
+We removed the `@storybook/postinstall` package, which provided some utilities for addons to programmatically modify user configuration files on install. This package was years out of date, so this should be a non-disruptive change. If your addon used the package, you can view the old source code [here](https://github.com/storybookjs/storybook/tree/release-7-5/code/lib/postinstall) and adapt it into your addon.
