Where it tells you that the release builds are unsupported while
the current builds are supported.
(That's at least what we tried to communicate, improvements

(Continuing a discussion I had with several people who archive.)
I wonder if this is all intentional (seriously!), you have a
specification that from all I know is unclear, multiple different
and incompatible implementations and several commercial
applications that tell you what's wrong in the files - but
nobody seems to be very interested in fixing these "issues".

Several tickets exist (including very old ones), I may be
closing them because they can't be reproduced.
