There's a "Preface to the Second Edition" near the front, which has a summary of changes. Main points are: 1) notation was overhauled, 2) Chapters 2-8 were reworked to only use tabular methods, with function approximation introduced later; 3) the function approximation coverage is then greatly expanded in the second section of the book (Chs. 9-13); and 4) new chapters 14-15 on connections between RL and psychology and neuroscience.
The scope is generally about the same though, perhaps because it's intended to be used as a single-semester textbook, so there isn't a big expansion into areas of RL other than those covered in the first edition (e.g. POMDPs are only briefly mentioned).
