 # @apollo/client
 
+## 4.3.0-alpha.0
+
+### Minor Changes
+
+- [#13250](https://github.com/apollographql/apollo-client/pull/13250) [`bad7035`](https://github.com/apollographql/apollo-client/commit/bad7035565e15c18800080d9e0abf1d89b3d82fa) Thanks [@jerelmiller](https://github.com/jerelmiller)! - Add the ability to define the cache type for the client. `client.cache` currently returns `ApolloCache` as the cache type regardless of what cache you've provided to `ApolloClient`.
+
+  Declare the cache type using the `cache` property in the `TypeOverrides` interface to set the cache implementation used for the client.
+
+  ```ts
+  // apollo.d.ts
+  import type { InMemoryCache } from "@apollo/client";
+
+  declare module "@apollo/client" {
+    export interface TypeOverrides {
+      cache: InMemoryCache;
+    }
+  }
+  ```
+
+  Now anywhere `cache` is accessible, the type is the declared cache type:
+
+  ```ts
+  client.cache;
+  //     ^? InMemoryCache
+
+  client.mutate({
+    update: (cache) => {
+      //     ^? InMemoryCache
+    },
+  });
+  ```
+
+  > [!NOTE]
+  > Setting a cache type enforces that cache type in the `cache` option for the `ApolloClient` constructor.
