# Rx Release History v6.0

## v6.0.1-preview

This release fixes [Issue #1942: "AOT compilation produces single trim analysis warning"](https://github.com/dotnet/reactive/issues/1942)

## v6.0.0

### Breaking changes

* Out-of-support target frameworks (.NET Core 3.1, .NET 5) removed
* Minimum target platform for UWP apps raised from 10.0.16299.0 to 10.0.18362.0

### New features

* Tested against .NET 6, and .NET 7
* When unhandled exceptions from `Task` used to cause `TaskScheduler.UnobservedExceptions`, applications can opt into swallowing failures silently (to be consistent with how Rx has always handled unhandled exceptions in the equivalent non-Task-oriented scenarios; this only applies to cases in which Rx has no way of reporting the exception, typically because the relevant observable no longer has any subscribers on which we could call `OnError`)
* `SingleAssignmentDisposableValue` type is now public
* Trimming annotations now present
* debug symbols now available as separate `snupkg` instead of being built in, reducing assembly size
