## 11.4.0 (2023-08-16)

### Enhancements
* Added `IQueryable.SubscribeAsync` API as a shorthand for using `SubscriptionSet.Add`. It is a syntax sugar that roughly translates to:
 ```csharp
 realm.Subscriptions.Update(() =>
 {
   realm.Subscriptions.Add(query);
 });

 await realm.Subscriptions.WaitForSynchronization();

 // This can now be expressed as
 await query.SubscribeAsync();
 ```
 It offers a parameter to control whether to wait every time for synchronization or just the first time a subscription is added, as well as cancellation token support. (PR [#3403](https://github.com/realm/realm-dotnet/pull/3403))
* Added an optional `cancellationToken` argument to `Session.WaitForDownloadAsync/WaitForUploadAsync`. (PR [#3403](https://github.com/realm/realm-dotnet/pull/3403))
* Added an optional `cancellationToken` argument to `SubscriptionSet.WaitForSynchronization`. (PR [#3403](https://github.com/realm/realm-dotnet/pull/3403))
* Fixed a rare corruption of files on streaming format (often following compact, convert or copying to a new file). (Core 13.17.1)
* Trying to search a full-text indexes created as a result of an additive schema change (i.e. applying the differences between the local schema and a synchronized realm's schema) could have resulted in an IllegalOperation error with the error code `Column has no fulltext index`. (Core 13.17.1)
* Sync progress for DOWNLOAD messages from server state was updated wrongly. This may have resulted in an extra round-trip to the server. (Core 13.17.1)
* Added option to use managed WebSockets ([`System.Net.WebSockets.ClientWebSocket`](https://learn.microsoft.com/en-us/dotnet/api/system.net.websockets.clientwebsocket)) instead of Realm's built-in WebSocket client for Sync traffic. Managed WebSockets offer improved support for proxies and firewalls that require authentication. This feature is currently opt-in and can be enabled by setting `AppConfiguration.UseManagedWebSockets` to true. Managed WebSockets will become the default in a future version. ([PR #3412](https://github.com/realm/realm-dotnet/pull/3412)).
* Fixed an issue that would make `realm.SyncSession` garbage collected even when there are subscribers to `realm.SyncSession.PropertyChanged`.

### Fixed
* Fixed a race condition between canceling an async write transaction and closing the Realm file, which could result in an `ObjectDisposedException : Safe handle has been closed` being thrown. ([PR #3400](https://github.com/realm/realm-dotnet/pull/3400))
* Fixed an issue where in the extremely rare case that an exception is thrown by `Realm.RefreshAsync`, that exception would have been ignored and `false` would have been returned. ([PR #3400](https://github.com/realm/realm-dotnet/pull/3400))
* Fixed the nullability annotation of `SubscriptionSet.Find` to correctly indicate that `null` is returned if the subscription doesn't exist in the subscription set. (PR [#3403](https://github.com/realm/realm-dotnet/pull/3403))
* Fixed an issue where executing `Filter` queries using remapped properties would only work with the native name rather than the managed one. Now both will work - e.g.:
 ```csharp
 partial class MyModel : IRealmObject
 {
   [MapTo("Bar")]
   public int Foo { get; set; }
 }

 // Both of these are valid now
 realm.All<MyModel>().Filter("Foo > 5");
 realm.All<MyModel>().Filter("Bar > 5");
 ```
 (Issue [#3149](https://github.com/realm/realm-dotnet/issues/3149))
