I have always tried to explain my collections of stories as tightly as possible, even by the title itself or by one sentence, literally. So, the sentence about "Tom 2.0" is:
On the occasion of my 30th birthday, I decided to gather together and put between the covers of "Tom 2.0" the optimized version of the stories in my first three books: "Footnotes" (2005), "Footnote Tales" (2008) and "Calendar of Short Stories" (2011); I hope you will love this version (the last part of the sentence is the most important).
