Let me clarify my question. I bought this version of the book and
checked to see if the PDF version had been updated. It looks like a new
version was released last week and I downloaded the update.
What I’m wondering is, what arethe differences between the version
released in December and the one released last week?
Was my response to your original email most by the gateway?
If so, I said:
Just look at the errata page, and select the version of the PDF you currently have in the drop down. The stuff shown in less-saturated colors has been fixed between your edition and the current one.
(Basically, I fixed some errata while readying the book for the second printing)
