Werner, Why is it so hard to understand that a release, even for data files, needs to follow a process? Why do we always need to have a never-ending list of messages (10 from you alone on this thread) for simple things? Why do we always need to point fingers at other projects when the release process is the same for every ASF project?
Instead of writing 10 messages you could have spent that time more productively by just preparing the signed release archive... Just a FYI: the Sling example you're pointing at with a not-working URL is actually the expansion of a *signed release archive* - http://apache.org/dist/sling/org.apache.sling.ide.p2update-1.1.0.zip - and is there for convenience.
