pip install decocare installs version 0.0.30 of decocare, but the latest release is 0.0.31. pip install decocare --upgrade does not upgrade to 0.0.31 either.
On the other hand, easy_install decocare and easy_install -U decocare correctly install/upgrade to 0.0.31.
pypi shows 0.0.31 as the latest release:
