By now Goi.bin reached a HUUUGE size, more than 500 MB!! Even Goi.ctg has becomed larger than the actual DON.
But don't be confused: changes are not only in size - there have been alot of changes on subvariants, adding new preferred lines especially in A28 (English Opening) both in the BIN and the CTG formats. Hurnavich's tournament was enlightening, I've discovered some cool new move to set as favorite in early/middle/late opening thanks to it. The merit goes to the books of janus and Scorpio who discovered better variants.

Goi opens 1.c4 (English opening - A10), 1.e4 (King's pawn opening - B00) and 1.d4 (Queen's pawn opening or Queen's pawn game - A40) as White, 1 ...e5 to 1.c4 (English opening - A20), 1 ...e5 to 1.e4 (King's pawn game - C20), 1 ...Nf6 to 1.d4 (Queen's pawn game - A45), 1 ...Nf6 to 1.Nf3 (Reti opening - A05), 1 ...e5 to 1.g3 (Benko's Opening - A00), 1 ...e5 to 1.b3 (Nimzovich-Larsen attack, modern variation - A01) and 1 ...d5 to 1.f4 (Bird's opening - A03) as Black.
I've considered the Sicilian defense not enough productive as Black because the book received too many losses and the positional evaluation score was too high for the White right from the start.
By now the lines for any opening up to the 10th move are so accurate that I can tell this book is not anymore only adviced for blitz games but for correspondence chess too, if you strictly follow the green moves (CTG version). In facts I have checked them and fixed them for years versus the strongest opponents books and players using a serie of always more powerful tools; the last one in this list is the stabels monster machine with the newest Stockfish and 126 threads.
I feel pretty confident to tell that the BIN version is slightly stronger because of a Fritz crazyness in which the interface makes move the engine unaccordingly to the book, while its Polyglot counterpart is directly connected to the UCI engine, therefore it forces to move with its variants. The BIN book in Droidfish is also slightly better on the first move for White as it shows the correct percentage, unlike the CTG one (this issue is present only in the White first move anyway, just set Book Randomization to 50% if you have the CTG version and you are good to go).
