It's been five years since a printed book for Csla was made, and with 4.X it seemed that the new model was "framework is free, but ebooks on how to use it must be purchased." That model is fine for me, but I'm wondering if there are new ebooks coming for 4.5.
I ask because I'm trying to get Csla adopted here, especially on my team, because I think it would help us out quite a bit. Format training isn't an option for the team (some of the team is across the globe), and while I can say "here are the ebooks we'll need" that gets us to 4.0, and I'm not sure how to get the last bit to 4.5. I assume there are new features, and while I know about the issue tracker, the descriptions there don't always go into why there is a change or what it means for users.
Is there newer documentation coming, or are things not as different as I'm expecting, or is there a "quick guide to new features of 4.5" somewhere that goes into some depth about the features.
