-Provide a codemod that applies `@unmask` to all named fragments for all operations and fragments. To use the codemod, run the following command:
-
-```
-npx jscodeshift -t node_modules/@apollo/client/scripts/codemods/data-masking/unmask.ts --extensions tsx --parser tsx path/to/app/
-```
-
-To customize the tag used to search for GraphQL operations, use the `--tag` option. By default the codemod looks for `gql` and `graphql` tags.
-
-To apply the directive in migrate mode in order to receive runtime warnings on potentially masked fields, use the `--mode migrate` option.
-
-For more information on the options that can be used with `jscodeshift`, check out the [`jscodeshift` documentation](https://github.com/facebook/jscodeshift).

-Introduces data masking into Apollo Client. Data masking allows components to access only the data they asked for through GraphQL fragments. This prevents coupling between components that might otherwise implicitly rely on fields not requested by the component. Data masking also provides the benefit that masked fields only rerender components that ask for the field.
-
-To enable data masking in Apollo Client, set the `dataMasking` option to `true`.
-
-```ts
-new ApolloClient({
-  dataMasking: true,
-  // ... other options
-})
-```
-
-You can selectively disable data masking using the `@unmask` directive. Apply this to any named fragment to receive all fields requested by the fragment.
-
-```graphql
-query {
-  user {
-    id
-    ...UserFields @unmask
-  }
-}
-```
-
-To help with migration, use the `@unmask` migrate mode which will add warnings when accessing fields that would otherwise be masked.
-
-```graphql
-query {
-  user {
-    id
-    ...UserFields @unmask(mode: "migrate")
-  }
-}
-```

+#### Data masking 🎭
+
+- [#12042](https://github.com/apollographql/apollo-client/pull/12042) [`1c0ecbf`](https://github.com/apollographql/apollo-client/commit/1c0ecbf3c0454056853dd3dcb493dfd5fa1a96b1) Thanks [@jerelmiller](https://github.com/jerelmiller)! - Introduces data masking in Apollo Client.
+
+  Data masking enforces that only the fields requested by the query or fragment is available to that component. Data masking is best paired with [colocated fragments](https://www.apollographql.com/docs/react/data/fragments#colocating-fragments).
+
+  To enable data masking in Apollo Client, set the `dataMasking` option to `true`.
+
+  ```ts
+  new ApolloClient({
+    dataMasking: true,
+    // ... other options
+  });
+  ```
+
+  For detailed information on data masking, including how to incrementally adopt it in an existing applications, see the [data masking documentation](https://www.apollographql.com/docs/react/data/fragments#data-masking).
+
