# Changelog

## Version 2.3.0-beta1
- Changed behavior for `TelemetryConfiguration.Active` and `TelemetryConfiguration` dependency injection singleton: with this version every WebHost has its own `TelemetryConfiguration` instance. Changes done for `TelemetryConfiguration.Active` do not affect telemetry reported by the SDK; use `TelemetryConfiguration` instance obtained through the dependency injection. [Fix NullReferenceException when sending http requests in scenario with multiple web hosts sharing the same process](https://github.com/Microsoft/ApplicationInsights-dotnet/issues/613)
- Updated Javascript Snippet with latest from [Github/ApplicationInsights-JS](https://github.com/Microsoft/ApplicationInsights-JS)

- [Enforced limits of values read from incoming http requests to prevent security vulnerability](https://github.com/Microsoft/ApplicationInsights-aspnetcore/pull/608)
- [ApplicationInsightsLogger adds EventId into telemetry properties. It is off by default for compatibility. It can be switched on by configuring ApplicationInsightsLoggerOptions.](https://github.com/Microsoft/ApplicationInsights-aspnetcore/issues/569)
- [ApplicationInsightsLogger logs exceptions as ExceptionTelemetry by default. This can now be configured with ApplicationInsightsLoggerOptions.TrackExceptionsAsExceptionTelemetry] (https://github.com/Microsoft/ApplicationInsights-aspnetcore/pull/574)
- [Add App Services and Azure Instance Metedata heartbeat provider modules by default, allow user to disable via configuration object.](https://github.com/Microsoft/ApplicationInsights-aspnetcore/pull/627)
