+#### 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 This package was years out of date, so this should be a non-disruptive change.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.
