The book has been selling very well–remaining in Amazon’s top 2000 titles–and the first printing has apparently sold out much more quickly than expected. If they had known how soon a second printing would be necessary, they would have printed more. In any case, O’Reilly has worked with us to go well above and beyond the norm for a second printing: not only have we fixed errata, we even went as far as rearranging page breaks and moving figures to improve readability. The second printing is on Monday August 4th.
To clarify, this is a second printing of the second edition, not an entirely new edition. As each print run sells out there will be more printings to meet demand.
The book is also going to be translated into Spanish, Polish, and Portuguese. Further translations may be announced in the future.
