Calling-DrawText-and-DrawHeaderText-from-a-code-library-since-WL8-Build-12

In the past I passed an instance of UserStrategyBase (usb.) into my DLL libraries to access DrawText and DrawHeaderText. Now the VS Object Browser is telling me these methods belong to WealthLab.Backtest instead. Is this really true? If I'm including a "using WealthLab.Backtest" statement in my DLL libraries, does that mean I can call DrawText and DrawHeaderText without prefixes now? (There's nothing about this in the release notes.) Or should I be using a different kind of prefix for these methods now?

CODE:
public void ShowCornerMsg(string cornerMsg, TimeSeries ts2frame, string messagePane, double hue = 0.5, int fontSize = 11)
{     ...
      WLFont cornerFont = new WLFont("Arial", fontSize, isBold: true);
      usb.DrawText(cornerMsg, ts2frame.Count-17, yPosition, msgColor, fontSize, messagePane, false, cornerFont);
}

When making breaking changes like this that require modifications of code libraries, it would be nice if WleathLab's "minor version" is incremented (8.0.10 -> 8.1.0) so we know libraries will be breaking and need recompilation.
