  • There are improvements in the NuGet install scripts (thanks to Caio Proiete for the encouragement and help with this).

  • There are some minor fixes, including the XlCall fix for the error: "Cannot Inherit from sealed class XlCall"

  • Installing the new (pre-release) ExcelDna.AddIn package version 0.33.8-rc2
