Thanks!

@bdukes I just want to make sure - this only impacts the comments correct? Not the actual binding.

[bdukes]

Good question. I've confirmed that the only usage of the Version property set by that constructor argument is in the comment header

Dnn.Platform/DNN Platform/Library/Services/Installer/XmlMerge.cs

Lines 643 to 648 in 045097a

	string commentHeaderText = string.Format(
	Localization.GetString("XMLMERGE_Upgrade", Localization.SharedResourceFile),
	Environment.NewLine,
	this.Sender,
	this.Version,
	DateTime.Now);
