# The admin panel RBAC system has been updated

> Source: https://docs.strapi.io/cms/migration/v4-to-v5/breaking-changes/admin-panel-rbac-store-updated

Strapi 5 removes the `content-manager_rbacManager` redux store section and uses the regular permissions system with an updated `useRBAC` hook instead.

In Strapi 5, the `content-manager_rbacManager`, which is a section of Strapi's redux store for the admin panel, is removed and the regular permissions system is used instead. Additionally, the `useRBAC` hook is updated.

This page is part of the [breaking changes database](/cms/migration/v4-to-v5/breaking-changes) and provides information about the breaking change and additional instructions to migrate from Strapi v4 to Strapi 5.

## Breaking change description

**In Strapi v4**

Permissions are handled with the `content-manager_rbacManager` section of the redux store, like in the following generic example:

```tsx
const cmPermissions useSelector(state => state['content-manager_rbacManager'])
```

```tsx
const { allowedActions } = useRBAC({
	main: [{ action: 'admin::something.main', subject: null }]
})

const canMain = allowedActions.canMain
```

**In Strapi 5**

`content-manager_rbacManager` is removed and the regular permissions system is used instead, which implies the `useRBAC` hook is used differently, as in the following generic example:

```tsx
const { allowedActions } = useRBAC([
  { action: 'admin::something.main', subject: null }
])

const canMain = allowedActions.canMain
```

## Migration

This section regroups useful notes and procedures about the introduced breaking change.

### Notes

<!-- TODO v5: update links when v5.contributor.strapi.io is hosted at contributor.strapi.io -->
* A new RBAC API is available and users can utilise a middleware system to interact with calls (see [contributors documentation](https://contributor.strapi.io/exports/classes/StrapiApp#addrbacmiddleware)).
* Additional information can be found in the Contributors Documentation, in the [Fetching permissions](https://contributor.strapi.io/docs/core/admin/permissions/frontend/fetching-permissions) and [Authentication](https://contributor.strapi.io/docs/core/admin/features/authentication) sections.

### Manual migration

Plugin developers that are hooking into the redux store to tweak RBAC permissions in Strapi v4 need to update their code according to the described changes.
