 # @apollo/client
 
+## 4.0.0-alpha.10
+
+### Major Changes
+
+- [#12559](https://github.com/apollographql/apollo-client/pull/12559) [`49ace0e`](https://github.com/apollographql/apollo-client/commit/49ace0e2119b7fd5997dcf051002ebd4ba2e0bc4) Thanks [@jerelmiller](https://github.com/jerelmiller)! - `ObservableQuery.variables` can now be reset back to empty when calling `reobserve` with `variables: undefined`. Previously the `variables` key would be ignored so `variables` would remain unchanged.
+
+- [#12559](https://github.com/apollographql/apollo-client/pull/12559) [`49ace0e`](https://github.com/apollographql/apollo-client/commit/49ace0e2119b7fd5997dcf051002ebd4ba2e0bc4) Thanks [@jerelmiller](https://github.com/jerelmiller)! - `never` is no longer supported as a valid `TVariables` generic argument for APIs that require `variables` as part of its type. Use `Record<string, never>` instead.
+
+- [#12559](https://github.com/apollographql/apollo-client/pull/12559) [`49ace0e`](https://github.com/apollographql/apollo-client/commit/49ace0e2119b7fd5997dcf051002ebd4ba2e0bc4) Thanks [@jerelmiller](https://github.com/jerelmiller)! - When passing a `variables` key with the value `undefined`, the value will be replaced by the default value in the query, if it is provided, rather than leave it as `undefined`.
+
+  ```ts
+  // given this query
+  const query = gql`
+    query PaginatedQuery($limit: Int! = 10, $offset: Int) {
+      list(limit: $limit, offset: $offset) {
+        id
+      }
+    }
+  `;
+
+  const observable = client.query({
+    query,
+    variables: { limit: 5, offset: 0 },
+  });
+  console.log(observable.variables); // => { limit: 5, offset: 0 }
+
+  observable.reobserve({ variables: { limit: undefined, offset: 10 } });
+  // limit is now `10`. This would previously be `undefined`
+  console.log(observable.variables); // => { limit: 10, offset: 10 }
+  ```
+
+- [#12562](https://github.com/apollographql/apollo-client/pull/12562) [`90bf0e6`](https://github.com/apollographql/apollo-client/commit/90bf0e61516a382182f212ac8ab891099e2eb009) Thanks [@jerelmiller](https://github.com/jerelmiller)! - `client.query` no longer supports a `fetchPolicy` of `standby`. `standby` does not fetch and did not return `data`. `standby` is meant for watched queries where fetching should be on hold.
+
+### 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));
+  }
+  ```

+- [#12559](https://github.com/apollographql/apollo-client/pull/12559) [`49ace0e`](https://github.com/apollographql/apollo-client/commit/49ace0e2119b7fd5997dcf051002ebd4ba2e0bc4) Thanks [@jerelmiller](https://github.com/jerelmiller)! - The `variables` option used with various APIs are now enforced more consistently across the client when `TVariables` contains required variables. If required `variables` are not provided, TypeScript will now complain that it requires a `variables` option.
+
+  This change affects the following APIs:
+
+  - `client.query`
+  - `client.mutate`
+  - `client.subscribe`
+  - `client.watchQuery`
+  - `useBackgroundQuery`
+  - `useQuery`
+  - `useSubscription`
+  - `useSuspenseQuery`
+
+- [#12559](https://github.com/apollographql/apollo-client/pull/12559) [`49ace0e`](https://github.com/apollographql/apollo-client/commit/49ace0e2119b7fd5997dcf051002ebd4ba2e0bc4) Thanks [@jerelmiller](https://github.com/jerelmiller)! - Fix type of `variables` returned from `useLazyQuery`. When `called` is `false`, `variables` is now `Partial<TVariables>` instead of `TVariables`.
+
+- [#12562](https://github.com/apollographql/apollo-client/pull/12562) [`90bf0e6`](https://github.com/apollographql/apollo-client/commit/90bf0e61516a382182f212ac8ab891099e2eb009) Thanks [@jerelmiller](https://github.com/jerelmiller)! - `client.query` no longer supports `notifyOnNetworkStatusChange` in options. An error will be thrown if this option is set. The effects of this option were not observable by `client.query` since `client.query` emits a single result.
+
+- [#12557](https://github.com/apollographql/apollo-client/pull/12557) [`51d26ae`](https://github.com/apollographql/apollo-client/commit/51d26ae631c6631a189c98ea9357b18e77a9a876) Thanks [@jerelmiller](https://github.com/jerelmiller)! - Update format of the error message for `CombinedGraphQLErrors` and `CombinedProtocolErrors` to be more like v3.x.
+
+  ```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`
+  ```

This is more consistent with the runtime value where an empty object (`{}`) will be returned when the `variables` option is not provided.
