VDL Demystified was written for Finale 2011. Finale 2012 has several improvements that will make working with VDL more productive. Template updates for VDL 2.5.5 should be available soon. They will be compatible with Finale 2012 only. Updates for previous versions of Finale (2010 and 2011) may be developed but there is no timeline for completion at this time. Know also that there will be no Finale 2013 released. So installing 2012 and getting comfortable would be a good idea. Hope that answers some of your questions.
