 # @apollo/client
 
+## 4.0.0-alpha.10
+
+### Minor Changes
+
+- [#12557](https://github.com/apollographql/apollo-client/pull/12557) [`51d26ae`](https://github.com/apollographql/apollo-client/commit/51d26ae631c6631a189c98ea9357b18e77a9a876) Thanks [@jerelmiller](https://github.com/jerelmiller)! - Add ability to specify message formatter for `CombinedGraphQLErrors` and `CombinedProtocolErrors`. To provide your own message formatter, override the static `formatMessage` property on these classes.
+
+  ```ts
+  CombinedGraphQLErrors.formatMessage = (
+    errors,
+    { result, defaultFormatMessage }
+  ) => {
+    return "Some formatted message";
+  };
+
+  CombinedProtocolErrors.formatMessage = (errors, { defaultFormatMessage }) => {
+    return "Some formatted message";
+  };
+  ```
+
+- [#12546](https://github.com/apollographql/apollo-client/pull/12546) [`5dffbbe`](https://github.com/apollographql/apollo-client/commit/5dffbbe407eb1d9adbcb0fff89f2d3a75dc1ad2b) Thanks [@jerelmiller](https://github.com/jerelmiller)! - Add a static `is` method to error types defined by Apollo Client. `is` makes it simpler to determine whether an error is a specific type, which can be helpful in cases where you'd like to narrow the error type in order to use specific properties from that error.
+
+  This change applies to the following error types:
+
+  - `CombinedGraphQLErrors`
+  - `CombinedProtocolErrors`
+  - `ServerError`
+  - `ServerParseError`
+  - `UnconventionalError`
+
+  **Example**
+
+  ```ts
+  import { CombinedGraphQLErrors } from "@apollo/client";
+
+  if (CombinedGraphQLErrors.is(error)) {
+    console.log(error.message);
+    error.errors.forEach((graphQLError) => console.log(graphQLError.message));
+  }
+  ```

+
+  ```diff
+  console.log(error.message);
+  - `The GraphQL server returned with errors:
+  - - Email not found
+  - - Username already in use`
+  + `Email not found
+  + Username already in use`
