+
+::: info Why this change?
+The term `model` has been replaced with `collection` throughout the rstore codebase and API to better reflect its purpose and avoid confusion with Vue's own `defineModel` function and `v-model` API.
+:::
+
+```ts
+hook('fetchFirst', async ({ model, key, params }) => { // [!code --]
+hook('fetchFirst', async ({ collection, key, params }) => { // [!code ++]
+  // ...
+})
+```
