 - Fix [#2412](https://github.com/StackExchange/StackExchange.Redis/issues/2412): Critical (but rare) GC bug that can lead to async tasks never completing if the multiplexer is not held by the consumer ([#2408 by mgravell](https://github.com/StackExchange/StackExchange.Redis/pull/2408))
 - Add: Better error messages (over generic timeout) when commands are backlogged and unable to write to any connection ([#2408 by NickCraver](https://github.com/StackExchange/StackExchange.Redis/pull/2408))
 - Fix [#2392](https://github.com/StackExchange/StackExchange.Redis/issues/2392): Dequeue *all* timed out messages from the backlog when not connected (including Fire+Forget) ([#2397 by kornelpal](https://github.com/StackExchange/StackExchange.Redis/pull/2397))
