A month ago, I have reported a release-tools' issue regarding malformed
json for release files:

It did get attention by Rene (I think), but it has not been fixed yet.
If we are going for RC4, could you merge this too?
The fix is trivial (just deleting 1 character), so it won't be that hard.

I'm having problems with automated checksum validation for my CI server,
because I can't feed this file to a formal JSON parser.
