Schema versioning

With this release of Crescendo, the JSON schema for the configuration is now versioned. While wedon’t expect there to be any changes, supporting a versioned schema makes is easier to supportchanges in future releases.

The URL for the current version of the schema is: https://aka.ms/PowerShell/Crescendo/Schemas/2021-11.

Support for empty string parameter values

Crescendo now supports parameters that accept empty strings as argument values. The proxy cmdletcreated by Crescendo now recognizes an empty string provided as parameter value and ensures that theempty string is passed as "" to the native executable.

For a more detailed example use case, seeIssue #100.

Displaying OriginalCommand in Help

The OriginalCommand property of a cmdlet definition is intended to contain the original nativecommand and parameters invoked by the proxy cmdlet. This information is display by Get-Help. Withthis release, if the OriginalCommand property is empty, no placeholder is written to thecomment-based help when the module is exported.
