### [`v1.21.0`](https://redirect.github.com/apollographql/apollo-ios/blob/HEAD/CHANGELOG.md#v1210)

[Compare Source](https://redirect.github.com/apollographql/apollo-ios/compare/1.20.0...1.21.0)

##### New

-   **Enhanced Client Awareness ([#&#8203;638](https://redirect.github.com/apollographql/apollo-ios-dev/pull/638)):** Apollo iOS now sends the library name and version as metadata in the `extensions` key of each request. This Enhanced Client Awareness metric is collected in GraphOS along with the existing Client Awareness and general operation metrics.

##### Improvement

-   **Removed SQLite.swift dependency ([#&#8203;635](https://redirect.github.com/apollographql/apollo-ios-dev/pull/635)):** Removed the dependency on `SQLite.swift` and replaced it with direct interaction with the SQLite C API.

##### Fixed

-   **Fix possible data races in the WebSocketTransport ([#&#8203;636](https://redirect.github.com/apollographql/apollo-ios-dev/pull/636)):** Fixes possible data race issues in the `subscriptions` property inside of `WebSocketTransport`. *Thank you to [@&#8203;tahirmt](https://redirect.github.com/tahirmt) for the contribution.*
-   **Fix cache reading of null list items ([#&#8203;3527](https://redirect.github.com/apollographql/apollo-ios/issues/3527)):** Null list items would previously generate a `wrongType` error if stored and read from the cache. This refactors the execution logic to correctly handle values from cache references in lists. See PR [#&#8203;637](https://redirect.github.com/apollographql/apollo-ios-dev/pull/637).
