Ok, I just looked at my bookshelf, and a bunch of (but not all) my TBRs are on it!  The ones that belong there have a green checkmark beside them, and the TBSs have the circle/slash over the checkmark.  But why are they there at all???  Did I miss another change?

Actually it is your bookshelf and books to repost list that is combined.  You can seperate them by the books on hold or not.    There is a long thread in CMT about this.

And the reason that not all your TBR book are there is because only the ones that you received through PBS are added there for repost...those that you have posted to your TBR from another source (Garage Sale, etc) are not listed there.  You can check mark (on the far right)  those books on the Bookshelf that are actually your TBR books and click to delete them...it will only delete them from your bookshelf but, will leave them on your TBR file.

Also, you will note you now have an option when you receive a book to put it there (on your repost/bookshelf list) or not....personally I don't.

Excellent, thank you Christy, I was wondering if I could safely delete them! 

I was wondering the same thing. Some of these books I just got and haven't read yet.
