Missing AddPdfPages() methods - version 1.5.0.6

[Pughgramming]

Overview

We've installed the latest version, 1.5.0.6, and were hoping to take advantage of a particular public static method that is found in the PdfGenerator.cs class in this library. Its signature is:
public static void AddPdfPages(PdfDocument document, string html, PdfGenerateConfig config, CssData cssData = null, EventHandler<HtmlStylesheetLoadEventArgs> stylesheetLoad = null, EventHandler<HtmlImageLoadEventArgs> imageLoad = null)

However, it seems this method actually doesn't exist in this latest version of the package installed through Nuget? Am I missing something? We have this package, the core package, and the PdfSharp package installed. HtmlRenderer.Core version is 1.5.0.6 as well. PdfSharp version is 6.2.2.
