Generally Available: Durable Functions PowerShell SDK as a standalone module

The Durable Functions PowerShell SDK is now available as a standalone module in the PowerShell Gallery: AzureFunctions.PowerShell.Durable.SDK. This SDK is now generally available and is the recommended approach for authoring Durable Functions apps with PowerShell. The SDK includes support for sub-orchestrations, as well as many highly requested improvements such as better exception and null-value handling, and serialization fixes.  

The previous Durable Functions PowerShell SDK was built into Azure Functions PowerShell language worker. This approach came with the benefit that Durable Functions apps could be authored out-of-the box for Azure Functions PowerShell users. However, it also came with various shortcomings, the biggest being that new features, bug fixes, and other changes were dependent on the PowerShell worker’s release cadence. This made it harder to quickly release improvements and changes requested by Durable Functions PowerShell users, thus motivating the building of the new standalone SDK.
