Using zest.releaser or manually uploading packages to plone.org by using...
python2.6 setup.py register -r plone.org sdist upload -r plone.org
...now seems broken. I get:
Upload failed (301): Moved Permanently
Before opening an issue to dev.plone.org I want to be sure that we didn't disabled this, I know there are some plans about replacing the products section with something different.
