Was there incompatible upgrade from "ReSharper.CLT.2018.2.3" to "CLT 2018.3.4"?

I have a plugin which worked in "ReSharper.CLT.2018.2.3" to detect "XAML" file issue.

Now it can't work in "ReSharper.CLT.2018.3.4". 

(But it still works in "ReSharper 2018.3.4")

The below code is used by my plugin:

    [DaemonStage(StagesAfter = new[] { typeof(LanguageSpecificDaemonStage) })]

    public class XamlFileDaeMonStage : DaemonStageBase<IXamlFile>

    {

    }
