* Android from `2.3.0` to [2.4.1](https://github.com/Microsoft/AppCenter-SDK-Android/releases/tag/2.4.1)
* iOS from `2.4.0` to [2.5.0](https://github.com/Microsoft/AppCenter-SDK-Apple/releases/tag/2.5.0)
* UWP from `2.1.0` to [2.5.0](https://github.com/Microsoft/AppCenter-SDK-DotNet/releases/tag/2.5.0)
### App Center
* **[Fix]** Fix `AppCenterStarter.m` was not included in the first build.
### App Center Crashes
#### Android
* **[Behavior change]** Fix a security issue with the `Exception` field on `ErrorReport` objects. As a result, the `Exception.StackTrace` now holds the raw stack trace, and the `Exception.Message` field is `null`.
### App Center Push
#### UWP
* **[Feature]** Allow developers to push notifications to a specific userId.
### App Center Distribute
#### Android
* **[Feature]** Downloading in-app update APK file has been failing on Android 4.x since TLS 1.2 has been enforced early September. The file is now downloaded using HTTPS direct connection when running on Android 4 instead of relying on system's download manager.
* **[Feature]** Fix a crash and improve logging when downloading an update fails on Android 5+.
* **[Behavior change]** If your minSdkVersion is lower than 19, Android requires the WRITE_EXTERNAL_STORAGE permission to store new downloaded updates. Please refer to the updated documentation site for detailed instructions. This is related to the download fix.
App Center Auth is a cloud-based identity management service that enables developers to authenticate application users and manage user identities. The service integrates with other parts of App Center, enabling developers to leverage the user identity to view user data in other services and even send push notifications to users instead of individual devices.

* Method `Crashes.HasCrashedInLastSession` renamed to `Crashes.HasCrashedInLastSessionAsync`
* Method `Crashes.LastSessionCrashReport` renamed to `Crashes.GetLastSessionCrashReportAsync` and now returns an instance of class `AppCenterTask<ErrorReport>`
* Handler for an event `Crashes.FailedToSendErrorReport` must now contain additional parameter with type `Microsoft.AppCenter.Unity.Crashes.Models.Exception`
