Maintenance Release for Akka.NET 1.4**
Akka.NET v1.4.21 is a significant release that includes major performance improvements, bug fixes, and a major update to the [Akka.DependencyInjection NuGet package](https://getakka.net/articles/actors/dependency-injection.html).
Performance Improvements**
Akka.NET v1.4.21 includes some major performance fixes and improvements:
[`Ask` is now ~10% faster](https://github.com/akkadotnet/akka.net/pull/5051)
[`MurmurHash` is 33% faster and allocates 0 memory](https://github.com/akkadotnet/akka.net/pull/5028) - used _heavily_ in DData, Cluster Sharding, and Consistent Hash Routers
`ActorPath.Parse` went from 1672 ns/op to 527 ns/op - a 68% improvement in throughput and a 50% reduction in memory. See [#5039](https://github.com/akkadotnet/akka.net/pull/5039) and [#5068](https://github.com/akkadotnet/akka.net/pull/5068).
[Akka.Remote: remove `ActorPath.ToString` call from `ResolveActorRefWithLocalAddress`](https://github.com/akkadotnet/akka.net/pull/5034)
Important**: [Revert `ThreadPool.SetMinThreads(0,0)`](https://github.com/akkadotnet/akka.net/pull/5059) - based on the input from users on "[Akka.NET v1.4.19: ChannelExecutor performance data](https://github.com/akkadotnet/akka.net/discussions/4983)"
Our observed performance numbers for Akka.Remote show a significant increase in performance for v1.4.21 over v1.4.20:

Akka.DependencyInjection Updates**
We had one major issue we implemented in v1.4.21 for Akka.DependencyInjection: [Abstraction of `ServiceProvider`, Improving Akka.DependencyInjection ](https://github.com/akkadotnet/akka.net/pull/4814)
What this change did was:
Deprecate the `Akka.DependencyInjection.ServiceProvider` class in favor of the `Akka.DependencyInjection.DependencyResolver` class - to avoid namespace collision with Microsoft.Extensions.DependencyInjection.ServiceProvider;
Deprecates the `Akka.DependencyInjection.ServiceProviderSetup` class in favor of the `Akka.DependencyInjection.DependencyResolverSetup` class for consistency reasons;
`Akka.DependencyInjection.DependencyResolver` now takes an input of type [`IDependencyResolver`](https://getakka.net/api/Akka.DependencyInjection.IDependencyResolver.html), which allows users to abstract away the `IServiceProvider` and mock / replace it during unit testing; and
Added some non-generic `Props` methods for dynamically spawning actors via DI.
All of these changes are backwards-compatible with v1.4.20 and earlier - and the deprecation warnings will appear in your code when you upgrade. If you run into any [issues upgrading to Akka.DependencyInjection v1.4.21 please reply on this thread](https://github.com/akkadotnet/akka.net/discussions/5070)!
