For excerpts I've seen, the book still contains the same mistakes for the first chapter, which was not engaging. Too bad though because the book is promising and well thought especially supplements that address parts outside programs or openings for culture (notions of group actions that will be seen in L3, music lines, etc.).
It is said that the algebra portion was revised ... Without having looked in depth, I found that the content is at first sight (emphasizing the "at first sight") the same, but just arranged differently (can -be to make it clearer than before? I do not know).
I would advise rather the ISDM book from the same publisher for L1 and L2 of the same authors book is great!
