Version 7.1.0
### 7.1.0
- Breaking Changes
- Remote Config: Changed `FirebaseRemoteConfig` to be an instanced class,
with new APIs to better manage fetching config data. The old static
methods are now deprecated, and can be accessed in the new class
`FirebaseRemoteConfigDeprecated`.
- Remote Config: `ConfigSettings.IsDeveloperMode` is now obsolete and does
nothing. `ConfigSettings.MinimumFetchInternalInMilliseconds` should be
adjusted instead.
- Changes
- General: Add GoogleServices-Info.plist to `Unity-iPhone` target in
Unity 2019.3+.
- Firestore: Fixed partial updates in `UpdateAsync()` with
`FieldValue.Delete`
([#882](https://github.com/firebase/quickstart-unity/issues/882)).
- Firestore: Fixed `DocumentSnapshot.ToDictionary()` on non-existent
documents when running on Android
([#887](https://github.com/firebase/quickstart-unity/issues/887)).
- Firestore: Fixed crash setting FirebaseFirestore.LogLevel on Android
before any instances have been created
([#888](https://github.com/firebase/quickstart-unity/issues/888)).
- Auth: Fixed a flaky crash when accessing the result from the task returned
by `FetchProvidersForEmailAsync`.
- Auth: You can now specify a language for emails and text messages sent
from your apps using UseAppLanguage() or setting the
FirebaseAuth.LanguageCode property.
- Messaging (Android): Using `enqueueWork` instead of `startService`.
Fixes bug where we lost messages with data payloads received when app
is in background.
([#877](https://github.com/firebase/quickstart-unity/issues/877)
- Remote Config: Fixed numeric value conversion `ConfigValue.DoubleValue`
and `ConfigValue.LongValue` to be locale independent.
- Installations: Fixed pod version to 7.5.0.
