No information which code was nonfree, no information how it was spotted. Rereleasing tarballs with the same verison number, which means there are now two official versions of the same tarball with the same version but with another md5 hash. In my opinion not the best information politics.

p.s.: Do they have a so small overview about the own code that they need 3 versions to detect that there is non free code in the release?
