The changes are:
Changed default API URL to use HTTPS (Joseph Hui).
PEP 8 compliance (Luar Roji).
Replaced Distribute with Setuptools.
In the mean time, we have made more progress on the upcoming version 2.0. We can always use more bug testers, bug fixers and documentation writers; check out https://bitbucket.org/sybren/flickrapi/ to get involved!
