Dear Colleagues and Friends, The first 6 chapters of Agile Artificial Intelligence are now stable. Now is a good time for reviewing them. The chapters are available online from: https://agileartificialintelligence.github.io/ You can also see that the structure of the book has evolved. I believe that the part are stable. Maybe content of Part II and Part III can still evolve. You can contribute to the chapters by simply making a pull-request. People who do so, (i) will have their name listed on the book website, (ii) will have their name in the printed version of the book, and (iii) I will be very happy to invite you for a beer next time we meet. Thanks to all of you who have pushed the book and sent encouragements. The community deserves your effort. Kind regards, Alexandre
