Hi
We originally wrote the books Creating & Using A Bug Free Mind back in 2010 and we will continually update these as we move on and learn more, after all the ideas that come out of reading the books will obviously mean things will change.
In July 2012 we set the wheels in motion and printed the second edition of these books, although the bulk of the content is the same, Andy has made changes to a lot of parts, adding in some more explanations and examples and hopefully making the reading experience better for all.
We finally took delivery of these second edition books on the 17th August 2012 and any books ordered after 15th July will be the second edition versions.
Obviously we have kept a few first edition copies back, mainly for our own use, but a few might be available to purchase if you submit a ticket, but these may not last long so I cannot offer any guarantees.
Best wishes,
Phil
