requires (Test-BuildAsset) uses ValidateNotNullOrEmpty , #238
Potentially but unlikely breaking, see the issue.
Removed undocumented alias Show-TaskHelp.
Use Invoke-Build -WhatIf or Show-TaskHelp.ps1.
Breaking if the undocumented alias was used.
Simplified Show-BuildTree.ps1, #236
Improved "Missing task" errors, #237
Added more details to about_InvokeBuild.help.txt.
