The releases API uses pagination, which defaults to 30 per page. If you want to get the 100 most recent you can make the following small change:

def dump_stats(repo):
    url = 'https://api.github.com/repos/%s/releases?per_page=100' % repo
    try:
        f = urllib.urlopen(url)

@kingthorin Good idea; updated. 👍
