 **Note:** This is a cumulative changelog that outlines all of the Apollo Client project child package changes that were bundled into a specific `apollo-client` release.
 
-## Apollo Client (vNext)
+## Apollo Client vNEXT
+
+- In production, `invariant(condition, message)` failures will now include
+  a unique error code that can be used to trace the error back to the
+  point of failure. <br/>
+  [@benjamn](https://github.com/benjamn) in [#4521](https://github.com/apollographql/apollo-client/pull/4521)
+
+### Apollo Client
+
+- Update the React Native docs to remove the request for external example
+  apps that we can link to. We're no longer going to manage a list of
+  external example apps.  <br />
+  [@hwillson](https://github.com/hwillson) in [#4531](https://github.com/apollographql/apollo-client/pull/4531)
+
+- If you can be sure your application code does not modify cache result objects (see `freezeResults` note below), you can unlock substantial performance improvements by communicating this assumption via
+  ```ts
+  new ApolloClient({ assumeImmutableResults: true })
+  ```
+  which allows the client to avoid taking defensive snapshots of past results using `cloneDeep`, as explained by [@benjamn](https://github.com/benjamn) in [#4543](https://github.com/apollographql/apollo-client/pull/4543).
+
+- Avoid updating (and later invalidating) cache watches when `fetchPolicy` is `'no-cache'`. <br/>
+  [@bradleyayers](https://github.com/bradleyayers) in [PR #4573](https://github.com/apollographql/apollo-client/pull/4573), part of [issue #3452](https://github.com/apollographql/apollo-client/issues/3452)
+
+### Apollo Cache In-Memory
+
+- Support `new InMemoryCache({ freezeResults: true })` to help enforce immutability. <br/>
+  [@benjamn](https://github.com/benjamn) in [#4514](https://github.com/apollographql/apollo-client/pull/4514)
+
+- Allow `IntrospectionFragmentMatcher` to match fragments against the root `Query`, as `HeuristicFragmentMatcher` does. <br/>
+  [@rynobax](https://github.com/rynobax) in [#4620](https://github.com/apollographql/apollo-client/pull/4620)
+
+## Apollo Client 2.5.1
+
+### apollo-client 2.5.1
+
+- Fixes `A tuple type element list cannot be empty` issue.  <br/>
+  [@benjamn](https://github.com/benjamn) in [#4502](https://github.com/apollographql/apollo-client/pull/4502)
+
+### graphql-anywhere 4.2.1
+
+- Adds back the missing `graphql-anywhere/lib/async` entry point.  <br/>
+  [@benjamn](https://github.com/benjamn) in [#4503](https://github.com/apollographql/apollo-client/pull/4503)
+
+
+## Apollo Client (2.5.0)
+
+### Apollo Client (2.5.0)
+
+- Introduces new local state management features (client-side schema
+  and local resolver / `@client` support) and many overall code improvements,
+  to help reduce the Apollo Client bundle size.  <br/>
+  [#4361](https://github.com/apollographql/apollo-client/pull/4361)
+- Revamped CJS and ESM bundling approach with Rollup.  <br/>
+  [@rosskevin](https://github.com/rosskevin) in [#4261](https://github.com/apollographql/apollo-client/pull/4261)
+- Fixes an issue where the `QueryManager` was accidentally returning cached
+  data for `network-only` queries.  <br/>
+  [@danilobuerger](https://github.com/danilobuerger) in [#4352](https://github.com/apollographql/apollo-client/pull/4352)
+- Fixed an issue in the repo `.gitattributes` that was causing binary files
+  to have their line endings adjusted, and cleaned up corrupted documentation
+  images (ref: https://github.com/apollographql/apollo-client/pull/4232).  <br/>
+  [@rajington](https://github.com/rajington) in [#4438](https://github.com/apollographql/apollo-client/pull/4438)
+- Improve (and shorten) query polling implementation.  <br/>
+  [PR #4337](https://github.com/apollographql/apollo-client/pull/4337)
+
