Release 3.7

April 7, 2021

When parent template is initialized with a PrintStream, any internal use of addPartial() should use implicitly that PrintStream regardless the output approach defined on the partial view instantiation.

This feature implies a couple of new internal methods including a newby() in HtmlVisitor that creates a new instance of same type and keeping indentation.
