Writing all these tests I sometimes felt that the changes between two days was not significant. And sometimes I felt there were versions that did not make it into this advent calendar. But I stuck with the versions you have seen since I think they represent a quite natural evolution of the initial test and hence I have not presented any side tracks that eventually turn into a dead end because I wanted to progress toward the final version which is the one I like most of all these versions. Also I had to be a little bit puristic and let even the smallest changes result in a version by it self rather than merging a number of small changes into a single version change in order get 24 different versions. There are however a few of the versions that I think are worth a special mentioning.
Please leave a comment and let me know what your favorite version in this series of test is!
For easier reference, here are the 2008 advent calendar links: Why and advent calendar? What problem?
December 11th is the right version
There is no "right version". Only a version you feel most comfortable with...
