If you are using tarball checksums to validate the tarball, github will
occasionally regenerate the tarball leading to a changed checksum. So if
you are validating tarballs before use, don't depend on stable checksums
from github automatically generated tarballs. Sadly, this makes github
auto created tarballs pretty useless.
