 ### Zerto Virtual Manager
 
 * Refactored `Copy-ZertoVpg` functionality to leverage identifier and name maps and eliminate `where-object` searches.
 * Updated `Get-ZertoEvent` parameter to fall in line with the filter parameter name in the API documentation. Moved the old parameter name to an alias to ensure that existing functionality continues to work.

 * A function has been added; `Copy-ZertoVpg`. This function will allow users to copy the settings of a single VPG and add new VMs to it. There is currently no customization beyond specifying the VMs to be placed in the newly created VPG. Should additional edits \ updates be required, they should be done post creation. [Issue 54](https://github.com/ZertoPublic/ZertoApiWrapper/issues/54)
 * Fixed [issue 57](https://github.com/ZertoPublic/ZertoApiWrapper/issues/57) where a `Start-ZertoFailoverTest` would throw an error complaining about validating the body parameter. This has been fixed and tested against Zerto Virtual Manager 7.5 Update 1 with Windows PowerShell 5.1 and PowerShell Core 6.2.

 * Updated the way that tests are invoked and parsed to ensure that both source and built module files are tested. This will ensure that what is being shipped passes all tests along with testing of the source files.
 * Added additional parameter validation tests to several of the functions. On-going effort to complete stand alone unit testing of each function.
