# Rx Release History v6.0

## v6.0.2

This release fixes:

* [Issue #2173: "RefCount with MinObservers > 1 Behaves Unexpectedly"](https://github.com/dotnet/reactive/issues/2173)
* [Issue #2214: "RefCount with disconnect delay and minObservers throws InvalidOperationException when resubscribing to synchronously completing source"](https://github.com/dotnet/reactive/issues/2214)
* [Issue #2215: "RefCount with disconnect delay and minObservers disconnects prematurely if observer count drops to zero and then goes back up"](https://github.com/dotnet/reactive/issues/2215)

Note: the test suite now tests on .NET 9.0. No changes were required as a result of this.

## v6.0.1
