I apologize for the delay in getting the Guidebook updated. I absolutely will and especially, though not exclusively, because it's such a great set of updates in 3.0 and 3.1. I hesitate to give a date but definitely this summer.
I have updated the workbooks to 3.0 and some 3.1 features. Not all features are included such as all the details about how to cross the Y axis at a certain point, but the procedures are included.
