Maintenance Release for Akka.NET 1.4
Akka.NET v1.4.23 is designed to patch an issue that occurs on Linux machines using Akka.Cluster.Sharding with akka.cluster.sharding.state-store-mode=ddata and akka.cluster.sharding.remember-entities=on: "System.DllNotFoundException: Unable to load shared library 'lmdb' or one of its dependencies"
In Akka.NET v1.4.21 we added built-in support for Akka.DistributedData.LightningDb for use with the remember-entities setting, but we never received any reports about this issue until shortly after v1.4.22 was released. Fundamentally, the problem was that our downstream dependency, Lightning.NET, doesn't include any of the necessary Linux native binaries in their distributions currently. So in the meantime, we've published our own "vendored" distribution of Lightning.NET to NuGet until a new official one is released that includes these binaries.
There are some other small fixes included in Akka.NET v1.4.23 and you can read about them here.

Akka.Cluster.Sharding.RepairTool
In addition to the work done on Akka.NET itself, we've also created a separate tool for cleaning up any left-over data in the event of an Akka.Cluster.Sharding cluster running with akka.cluster.sharding.state-store-mode=persistence was terminated abruptly before it had a chance to cleanup.
We've added documentation to the Akka.NET website that explains how to use this tool here: https://getakka.net/articles/clustering/cluster-sharding.html#cleaning-up-akkapersistence-shard-state
And the tool itself has documentation here: https://github.com/petabridge/Akka.Cluster.Sharding.RepairTool
