Today I released the first public version of Scikit-Learn (release notes). It's a python module implementing some machine learning algorithms, and it's shaping quite good.
For this release I did not want to do any incompatible changes, so most of them are just bug fixes and updates. For the next release, however, some more radical changes are planned, and definitely something should be done about the (incredibly long) namespace, having to tape from scikits.learn.machine.manifold_learning.regression.neighbors import Neighbors each time you want to perform a nearest-neighbor algorithms is just not practical!
