I actually tried to bump up the Cython requirement to 0.16 (see https://groups.google.com/forum/?fromgroups=#!topic/scikit-image/Fzdtoo8AUZ0) about a month ago, but that turned out to be **way** too soon.

For example, the current Ubuntu, 12.04, ships with Cython 0.15. I guess Ubuntu 12.10 will be released soon, and that release includes Cython 0.16. That said, I'm not sure if targeting the most recent Ubuntu is what we want to do (since it will be too fast for some people).

Andreas or Mathieu: Does scikit-learn have a policy for upgrading dependencies (in particular Cython)?

In scikit-learn, we've decided to use Cython 0.17 but we include generated .c files in the git repository so the dependency is only for developers who want to regenerate a particular .c file from the corresponding .pyx file... A downside is that this generates large and hard to read diffs but we recently merged a .gitattributes file that should alleviate this problem: https://github.com/scikit-learn/scikit-learn/blob/master/.gitattributes Mathieu
